Introduced to will solder finite yuan of new thinking that the method introduces fictitious production environment. Will solder of the process finite yuan of analysis is compositive to fictitious decrease in creating an environment, supportive product arrives from machining solder shape the design of whole process, the product that processes to needing to undertake soldering realizes process of fictitious design plant, before soldering actually, the design solders method, the program solders ordinal, forecast welding stress field, temperature field effectively, of weldment be out of shape circumstance, perfect fictitious production connotation, directive and actual production. 1 research purpose and meaning are fictitious production technology is a burgeoning advanced production technology, it is prop up with emulating IT and technology, virtual reality technology to be, to the design, make wait for manufacturing process to undertake building a model, have a product on the computer " make " , examine thereby the function of the product, performance characteristics and producibility. VM cent is fictitious production technology to be central VM in order to produce, mix in order to control for central VM it is central VM in order to design. The work plan that with producing the VM that is a center fictitious production system basically uses at the factory is made and workshop layout is emulated; Study those who be centered at producing a course in order to control to optimize for VM system of the center reach control model; It is products plan personnel in order to design to offer product information to optimize product and technology design in design phase for central VM. Its core idea is: Will make news fetching design process, use emulate optimize products plan, can be opposite in design phase thereby the spare parts is overall even undertake producibility is analysed, the craft analysis that includes to machine a process, thermodynamic analysis that casts a process, kinematic analysis of athletic component and dynamical credit analyse, including a small bay in a river such as analysis of precision of charge of handling time, treatment, treatment even basically is to solve " is the product that the design comes out what kind of " problem. Fictitious production technology is belonged to in home just started level, the VM that is a center in order to design for the most part at present studies concentration processes a product at the machine tool, if the semifinished product cutting of crucial part, cutting tool is interfered,wait for a problem. Tsinghua university automation ties the product development that began the rapier loom that is based on fictitious production technology, finish by CAD of three-dimensional model software above all camshaft and all spare parts modelling in bringing the abb, orgnaization that hit abb, make a part three-dimensional and hypostatic model; Read a person by ADAMS models of these spare parts substance, use much system of AD month Wu kinetic emulation function, define corresponding kinematic pair tie and drive tie, build fictitious prototype, consider a system kinematic to mix by ADAMS kernel solution again kinetic equation, to handing over abb orgnaization cooperate a relation to undertake emulation designing, get rapier loom is brought abb and those who hit abb orgnaization is kinematic with kinetic character, emulation output and design target undertake comparative, return CAD to adjust university of industry of Nanjing of parameter of relevant component structure to use research and development of fictitious production technology VE allocate pump, this orgnaization undertakes the fictitious design of the product above all, the kinematic analysis that undertakes athletic orgnaization ever since, kinetic analysis, will obtain a result to be defeated by a person to arrive finite yuan of analysis and structure are optimized, what had a product next is fictitious assemble, and had a key treatment of fictitious machine tool analyses In; Liu Jianhua, ning Ruxin, the person such as Zhang Xu puts forward to be aimed at the program that craft assembles inside fictitious production domain, this program method is face the spot be enmeshed partly type assembles program In; Institute of Dalian light industry is used will fictitious the research and development that production technology uses at graduation cam, module of the module of semifinished product preparation that basically studied in the link of fictitious treatment NC code translates module, spare parts, configuration of treatment machine tool, material excises emulation module to wait. · and in producing a course actually, a lot of component need to solder figuration, solder treatment also is a product in machining a process important segment, the geometrical dimension of welding line, mechanical function is the main index of product quality assess. As solder of the technology rise ceaselessly, solder automation rate is higher and higher also, this also solders to come true on the computer the imitate of the process raised new requirement, to soldering below fictitious production environment so the process undertakes the analysis is very necessary. Train of thought of 2 systems analysis solders below whole and fictitious production environment the structure is limited the system of yuan of analysis is shown 1 times like the graph. What study content according to its considering fictitious production system is different and OK cent is: It is a center in order to produce, mix in order to make for the center it is a center in order to design. Be united in wedlock to study a characteristic originally, side overweight solders structural design, the stress that studies so is to be put in the fictitious production direction that is a center with the design. Specific research train of thought is as follows: The graph solders below 1 fictitious production environment the structure is limited production of yuan of Nextpage (1) of analytic train of thought in a product in the process, want to pass a lot of treatment courses, include machine tool treatment, material to shape (namely v is machined) , plasticity treatment, solder treatment. Fictitious make those who emphasize is the development cycle with a complete product, and solder treatment is one of product treatment important segment, be necessary to consider to solder so how does the product undertake designing in VM environment, optimize, production. Include to determine geometrical size in the design that the process solders in fictitious environment, solder methodological choice, solder of parameter make, solder the operating mode condition of the process, determined these conditions only, ability undertakes the process is analysed soldering. (Before 2) was not soldering, according to experience really surely formulary perhaps estimation comes out all conditions, and what need in actual production is reasonable and effective parameter. Solder to rise quality, shorten the development time of the product, improve the beneficial result of the enterprise, be necessary ration analyses each parameter to be able to arise to solder what kind ofly quality, and finite yuan analytic method is a kind of very good numeric computation method, can undertake effective and accurate nonlinear analysis, forecast what different parameter condition falls to solder quality. (3) is trade those who have a lot of success application is finite yuan of analysis software, can have the aid of to soldering at these software the process undertakes numeric imitate. Be united in wedlock to research the fictitious production technology of heat at present, want to consider the impact of other treatment process in successive treatment already, want give attention to two or morethings to solder again process oneself characteristic, put forward finite to soldering below fictitious production environment yuan of analytic system. Distinguish at general finite yuan of analysis process, this system should consider a product in whole production cycle besides solder all treatment process of treatment, and traditional analytic procedure just is aimed at alone solder process, be defeated by a person to solder relevant parameter can. (4) studies to the development of this system the respect that needs a consideration has: How with fictitious production interface, solder user interface of the development of diagnostic library, graph and finite yuan of analysis processor. A.

How to come true namely with the interface of fictitious production environment with VM compositive, how be like with the other analysis of the product namely: Communicate kinetic analysis, kinematic analysis each other; How to realize data to share; How does analytic result feedback ceaselessly in each processes. B.

Traditional analytic software accepts simple geometrical message only, and as the bitter fleabane of the relevant technology such as the CAD suddenly develops, the diagnostic modelling that contains diagnostic information begins to appear, it is OK to use this kind of method will machine a process with more the angle that faces handlers appears come out. To soldering for the process, the feature is changed solder the geometrical model translate into that contact is a tradition is OK and convenient the contact model library of the choice, can decrease greatly solder the processing time before building a model, improve the efficiency that joint design works, use Marc better seek solution implement function. C.

Finite yuan of model reseau requirement that software needs to place is strict, and solder the process is to be out of shape greatly, the heating power disaster with nonlinear height combines a course, so the stand or fall of reseau quality is affected directly finite yuan seek solution implement operation circumstance, when the problem is serious, seek solution implement cannot work even. Be aimed at these problems, research is aimed at solder the reseau method of the problem, in order to discuss more of high quality finite yuan of analysis, use better finite yuan seek solution implement. D.

The stand or fall of graphical user interface matters to software directly the friendly degree to the client. Current finite yuan analytic software was to cover all sorts of application fields, the function is powerful, what this also brings about an interface directly is complex and trival, and finite yuan software basically is English interface, together with is right finite the plaque lack of yuan of knowledge, can affect the non-professional application to software, solder simply numeric imitate also has difficulty. Be aimed at this kind of circumstance, combine task characteristic, revise afresh finite the menu file of yuan of software, make general staff can be operated, can raise software utilization rate effectively, gain ground solder numerical value forecasts the application in factory workshop. The structure solders below 3 VM finite of yuan of analysis system put forward those who be based on fictitious production environment to solder finite if yuan of analysis system pursues 2 are shown. By the graph knowable, the system includes to solder parameter is defeated by person module 1, finite yuan before buy handles module 2, finite yuan of postposition processing module 3, auxiliary analysis module 4, finite yuan of analyzer 5, solder contact library 6, solder quality is evaluated 7, assemble sexual analysis 8, kinetic cent. The structure solders below graph 2 VM finite basis of yuan of analytic architecture Nextpage is factual the component of the product, be in fictitious the three-dimensional model plan that product part establishs in be being assembled beforehand. Adopt this three-dimensional model plan the * of format converter translate into in software.

Wrl format file, this file is the file type with geometrical acquiescent modelling. Right now, the spare parts model before the product did not solder can be viewed in virtual reality environment, and amid revises a model, through adding a few necessary node, define what what need to solder to assemble method beforehand for the model, include to solder method and parameter of direction of welding. Solder parameter is defeated by person module to solder mediumly method and direction of welding should be defeated by a person to arrive solder in analyzer, and with fictitious assemble an environment to have communication beforehand. Communication process is shown 3 times like the graph, include to contact interpolation of node of sensor, time sensor, script, azimuth among them implement or positional interpolation implement, pre-treatment module and solder structural model. Be in fictitious in assembling an environment beforehand, node of fetching contact sensor, time sensor node, osculatory sensor node includes to contact time parameter, perceptive user is clicked solder the time of the model, deliver this incident time sensor, time of change of value of the region in time sensor delivers azimuth interpolation implement or positional interpolation implement, azimuth interpolation implement or positional interpolation implement node is OK set waits for the travel of weldment to take route, after set is good, deliver displacement node, right now, open assemble a browser beforehand, through clicking an operation simply, can observe solder to rig a process beforehand. Osculatory sensor will engage time this one incident is delivered person incident parameter is defeated in script, script carries the Java script code of predefine, handle incident, handle namely solder the method that the model assembles beforehand, later, output incident delivers Mentat of Mare pre-treatment module, keep person Proc file, finish with finite the communication process of yuan of processor. Graph 3 VRML and finite the communication of yuan of pre-treatment realizes block diagram to make common welder in quality evaluation module art standard, consult according to actual condition relevant experience, solder certainly needs technology is normative, walk like voltage parameter, electric current parameter, welding torch speed, these parameter are passed finite the interface of pre-treatment user graph of yuan of software loses a person. Finite place needs yuan of processor solder contact model from solder call directly in contact library. So far, finite yuan of place in processor need parameter to decide respectively, begin finite yuan of analysis. Buy is handled before geometrical model, initiative condition, attrib border condition, load condition and data performance data include in module. Referenced and fictitious the geometrical modelling in be being assembled beforehand, in finite undertake be modificationed appropriately to the model in the pre-treatment interface of yuan of analyzer, decide the geometrical modelling of the problem; Place solders to undertake an analysis to the key in kinetic analysis, kinematic analysis, the border that obtains the buy before the result serves as to handle module or load condition input; What the input requires the performance of material. Finite yuan analyzer is finished solder finite yuan of analysis, its the result is deposited in result database. In finite yuan of aftertreatment module is medium open result data, can understand those who solder to be out of shape circumstance, the change of field of the temperature when soldering, stress field, the content of the database can analyse the basis of the evaluation as sequel. Will solder be out of shape data application is analysed at assembling a gender, get weldment and other part assemble a gender to evaluate a result, if solder,be out of shape big, the meeting when assembling causes interference, below this kind of circumstance, other analysis module is affected in auxiliary analysis module, need revises parameter, concrete step is as follows: In fictitious welding line position is adjusted in be being assembled beforehand, call the contact of other form in contact model library, adjust kinematic, kinetic in the active force of crucial part. Guidance of in order to of the temperature field in result data, stress field solders quality evaluation, like temperature or stress appears unusual, perhaps go against solder of the process undertake, make an assessment, the basis solders the effect, modification pre-treatment and solder the partial parameter in parameter module, wait like voltage parameter, electric current parameter, so far, finite yuan of analyzer recount, realize each parameter to revise the ceaseless feedback of the process, rise solder quality. 4 conclusion consider this to provide a compositive environment, combine fictitious production technology, the analysis that undertakes concerned soldering machining. Use fictitious the virtual reality technology that in making, make the user is felt and is enmeshed at the environment, make traditional finite yuan analytic process becomes intuitionistic, understand easily, what can let a non-professional undertake abstraction conveniently is finite yuan of analysis; Use fictitious the concept that data of the product in making manages, make solder analytic result and union of other analysis result rise, obtain a product result of switch of whole process data, analysis is interactive fictitious production effect, before undertaking product physics is produced namely, get emulation in the computer to including the treatment course that solders inside with the analysis, feedback evaluates the design in time to give a design the engineer in conception phase, design more reasonable process thereby; Use development language, union solders the characteristic of the process, development goes commonly used contact library model, geometry model, material function model to wait, make traditional parameter set operation turns into intuitionistic user chooses to operate, convenient with simplified finite yuan of analysis process.
