【摘要】 本文采用刚粘塑性有限元方法对影响轿车等速万向节球形壳缩口成形的各种因素加以模拟分析，得到了预锻件几何参数、摩擦因子与缩口成形性间的关系，并给出了成形不同阶段的速度矢量图。有限元模拟分析为球形壳模具设计以及缩口成形实验等工作的进行起到了指导作用。更多还原

【Abstract】 In this paper,influencing factors for necking deformation of limousine constant velocityjoint(CVJ) outerrace are analyzed by rigidviscous FEM method.The relation among deformation of necking preforge piece sizes and friction factor is obtained.Meantime,velocity vector drawings are presented.Die designing and experiment can be guided by this FEM numerical analysis.更多还原
