针对对轮旋压新工艺进行了刚塑性有限元分析。得出了在不同减薄率、不同进给速度时金属变形的速度场、应变速率场、应变场和应力场。计算所得旋压力与实验结果吻合较好。
A new rigid plastic finite element analysis of the wheel spinning technology was carried out. The velocity field, strain rate field, strain field and stress field of metal deformation at different thinning rates and different feed rates are obtained. The calculated spinning pressure agrees well with the experimental results.
