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.
