摘　　要：本文针对考虑各向异性的圆筒形件拉深工艺进行了仿真与实验研究.通过对比仿真与实验结果,验证了仿真模型与过程的正确性.通过有限元仿真分析,得到了拉深比及压边力对凸耳率的影响规律.The simulation and experiment researches have been carried on to the deep drawing of cylindrical parts considering anisotropy in the text.By comparing the simulation with the experiment result,the correctness of the simulation model and processes has been verified.The influence law of the drawing ratio and the blanking force on the earring rate has been obtained via the finite element simulation analysis.
