摘　　要：分析了保险杠的结构及性能要求,并研究了保险杠的气辅注射成型技术及工艺过程。运用CAE技术模拟保险杠充填过程,预测其成型质量,并结合实际生产条件优化出合理的气辅注射成型工艺参数。经实验研究,在优化的工艺条件下气体能较理想地穿透熔体,所生产的保险杠质量能满足用户的需求。The structure and capability requirement of auto-bumper were analyzed, and the gas assisted injection molding （GAIM） technology and its process were studied. The filling process of bumper was simulated by using CAE software, and the molding quality was predicted. The GAIM processing parameters of bumper were optimized combining with the practice. According to experimental research, the gas penetrated through the melt polymer commendably, and the product quality could satisfy the client＇s requirements.
