摘要
当前,有限元分析技术在汽车产品开发过程中发挥着不可替代的作用,在车身覆盖件、汽车结构及零部件及整车概念设计的同时,通过产品模拟分析、运动学、动力学仿真,在设计阶段发现设计中存在的缺陷、错误,及时改进优化。如车身的模具设计,通过对拉延工序进行冲压成形模拟分析,优化工艺参数,消除了拉裂、减薄、环状滑移线、起皱与回弹引起的成形缺陷。整车结构件通过CAE结构优化分析,从而大大缩短了产品的研制周期、减少了产品开发费用,全面提高了汽车整车性能和核心开发能力。
At present, finite element analysis technology plays an irreplaceable role in automobile product development process. At the same time of designing automobile body covering parts, automobile structure and components and vehicle concept, the defects and errors in the design are found in design stage through simulation analysis, kinematics and dynamics simulation for timely improvement and optimization. Such as body mold design, through analyzing stamping simulation of drawing process, process parameters are optimized to eliminate the forming defects caused by cracking, thinning, circular slip line, wrinkle and springback. The whole vehicle structure is optimized by CAE structure analysis, which greatly shortens the development cycle of the product, reduces product development costs, improves the vehicle performance and core development capability.
