摘要
本文利用有实验根据的变形流动模式建立动可容速度场 ,利用上限法模拟用实心坯料精锻直齿圆柱齿轮时坯料的外形尺寸变化和力—行程曲线 ,所得结果与实验测定值很一致 ,可供冲挤精锻工艺设计参考。
In this paper,the kinematically admissible velocity fields are established by using the metal flow patterns based on the experiments,and the configuration dimensions of billet and the curves of Load stroke in precision forging process for spur gear from solid billet are simulated on computer by Upper Bound Method.The results acquired in the simulation are in good agreement with those obtained in the experiments.
