摘　　要：以大翼子板作为研究对象,通过CAE仿真软件分析,针对大翼子板成形过程中出现的起皱叠料、开裂、滑移线等问题,基于设备限制和零件成形质量要求,结合冲压和焊接要求,从冲压工艺和零件结构2个方面提出优化方案。经CAE分析验证,大翼子板成形缺陷均得到解决,为后续类似零件的造型分析及设计提供参考。Taking a large fender as the research object,through the analysis of CAE simulation soft-ware,aiming at the problems such as wrinkling and folding material,cracking and slip line in the forming process,based on the device limitations and parts forming quality requirements,combined with stamping and welding requirements,the optimization scheme was put forward from the two aspects of process and part structure.Through CAE analysis and verification,the forming defects were solved,which provided references for the subsequent modeling analysis and design of similar parts.
