CAE Process Automation Systems Development For The Automotive Design And Study On Structure Optimization

As automobile design is pursuit for rapid response now, CAE analysis is alsofacing the urgent need to improve the efficiency, for many methods of CAE analysishave been standardized, develop CAE process automation systems is possible. Themain research of this content are:(1) Analysis of existing automotive design of finite element analysis process,from the finite element model, components, materials, and the definition of theattribute to the determination of the final analysis model, during a parse operationcumbersome and miscellaneous research using a scripting language improve theefficiency of modeling and finite element software secondary development tools.(2) For CAE analysis of automotive design which is relatively mature, such asstatic analysis, normal moods analysis, transient analysis, and frequency responseanalysis, the study of existing methods of operation, the development of processautomation systems, on the one hand, the existing engineering experience cured inworkflow system, on the other hand will analyze the workflow, and minimizeunnecessary cumbersome operations, improve the efficiency of the work of the CAE.(3)Use the door subsystem for example, apply the process automation system,checking a mini front side door sagging stiffness, free modal typical operatingconditions. Door outer panel dent resistance analysis and door strength of nationallaws and regulations, develop a dedicated process automation module, greatlyreducing the modeling time and improve the efficiency of the analysis, check resultsimprovement program to enhance the performance of the door.(4) On the basis of the process automation systems, carry out the automotivestructural optimization work to the body panel dent resistance optimization process,establish the position of the support plate, the installation in the form of variables, theuse of rapid prototyping script in the new structurally weak position variableconditions applied dent loaded optimization model, optimal performance optimizationanalysis structure, body panel anti-female member analysis and optimization toautomate the whole process.
