摘　　要：借助FASTAMP软件对中等深度锥形件在拉深过程中的应力应变进行分析,并从坯料直径、毛坯材料、压料面积和拉深工艺这4个因素分析其对径向拉应力的影响,以及径向拉应力对切向压应力的影响。研究表明:增大压料面积,并采用压力稳定的液压或气压的压边装置,可有效提高锥形件的径向拉应力,降低切向压缩所需的切向压应力,成功解决中等深度锥形件侧壁起皱的问题。In this paper,FASTAMP software is used to analyze the stress and strain of medium-depth conical parts in the process of deep drawing.The influences of blank diameter,blank material,pressing area and deep drawing process on radial tensile stress and radial tensile stress on tangential compressive stress are analyzed.The results show that the radial tensile stress of conical part can be effectively increased and the tangential compressive stress required by tangential compression can be reduced by increasing the pressing area and using hydraulic or pneumatic holder with stable pressure,and finally the problem of side-wall wrinkling of medium-depth conical parts can be successfully solved.
