利用有限单元法建立了钢管等径拔制仿真模型,对整个拔制过程进行仿真,得到了各种场变量的分布规律及特点,就模角和摩擦系数对拔制力的影响进行了研究,为实际生产提供参考。
The finite element method was used to establish the equal-diameter pipe drawing simulation model of steel pipe. The whole drawing process was simulated and the distribution law and characteristics of various field variables were obtained. The influence of die angle and friction coefficient on drawing force was studied. For the actual production of reference.
