摘　　要：本文提出汽车波形套成形的复合缩径—胀形工艺 ,设计了成形模具 ;给出了胀形用弹性介质体积及几何形状的确定原则 ;建立了波形套复合缩径—胀形力学模型 ,推导出各变形区的应力平衡方程 。In this paper,combined necking—bulging automobile corrugated sleeve technology is proposed. The deformation die is designed. The designed principle is given for determining the bulging elastic meson. The mechanical model for combined necking—bulging corrugated sleeve is founded. The stress equilibrium equations for deformation zones are deduced. The strain field and stress field are calculated on the basis of physical research.
