钛合金材料作为武器工程的主要材料,有着广泛的应用。本文利用刚黏塑性有限元方法,对钛合金深孔薄壁梭心套壳零件挤压成形过程进行了三维热力耦合数值模拟分析,获得了钛合金挤压成形时载荷与时间(或行程)的关系以及工件上的应力、应变、应变率和温度的分布信息。所得结果对产品加工工艺的制定和模具设计都具有指导意义。

Titanium alloy is widely used in the weapon industry.By using rigid visco-plastic method,a 3D thermo-mechanical coupled numerical simulation of the special long and thin-walled part for Titanium alloy during extrusion is carried out in this paper.The relations between the load and time(or stroke),the distribution rules of stress,strain,strain rate and temperature,which can be very useful,are obtained.This is helpful to the technology planning and the design of the dies.
