摘　　要：本文通过建立有限元模型,选择韧性断裂准则和断裂因子,研究冲裁速度对电机定转子铁芯冲裁断面质量影响的规律。通过实验获得电机定转子铁芯所用材料——硅钢片的真实应力应变曲线,并把此应力应变曲线运用于模拟中,通过设置不同的冲裁速度,得到不同的光亮带长度,从而可优化出最佳冲裁速度。分析对比模拟结果和实验结果,两者非常接近,可证明本研究对提高产品质量和生产效率有很好的借鉴作用。The finite element model has been have been selected in order to research the established. Theductile fracture criterion and fracture threshold influence of blanking speed on the blanked surface quality of motor stator and rotor core. The actual stress-strain curves of silicon which is the material of motor stator and rotor core has been obtained through test. The curve has been adopted into the simulation to set differ- ent blanking speed in order to get different bright band length. Thus in this way, the optimum blanking speed has been obtained. By analyzing and comparing the simulation result with the test result, it is found out that the two are very close. It is proved that this study provides reference for improving the product quality and productivity.
