Abstract:

An  automobile panel virtual display technology based on CATIA platform was proposed herein, CATIA CAA(component application architecture) dynamic response technology, triangle area coordinates method and spatial grid searching algorithm were  adopted aiming to settle the response speed  problem for searching large scale FE simulation results. Therefore, an  automobile panel stamping simulation post-processing system was designed and developed totally based on CATIA platform. The system was endowed with the ability to display and dynamic query comprehensive  information  such as stress, strain, thickness, shrink lines, skid lines and springback rapidly in large automobile panel stamping simulation. Thus the difficulties in the application of large scale CAE data post-processing on CATIA platform was successfully solved.

Key words: automobile panel, CATIA development, post-processing system, virtual display, dynamic query

摘要：

基于CATIA平台提出了汽车覆盖件大规模后处理结果虚拟显示技术,采用CATIA  CAA(component  application architecture)动态响应技术、三角形面积坐标法和空间格搜索算法解决了大规模有限元模拟结果的查询响应难题,设计开发了完全集成于CATIA平台的汽车覆盖件冲压成形模拟后处理系统。该系统可以快速显示和动态查询大型汽车覆盖件冲压成形模拟中的应力、应变、厚度、收缩线、滑移线、回弹量等信息,解决了在CATIA平台上难以实现大规模CAE数据后处理的问题。
