摘　　要：本文介绍了体积成形整体物理模拟技术的实施方案和主要技术要点 ,以及将该项技术用于模拟研究曲轴等典型锻件的成形过程 ,测定了变形力、错移力和关键部位的应变分布 ,提出了优化工艺设计。In this paper,the technique and scheme of entire physical simulation for bulk forming are introduced and discussed.This technique has been applied to simulate the forming process of crankshaft and another complex forging. The deformation force, offset force and strain field in the key position have been determined and analyzed systematically. Several methods which can effectively make process better, improve forging quality and reduce the wear of forging dies and equipment are proposed.
