TC2钛合金管材等温挤压过程的有限元模拟

摘要

The isothermal-extrusion process of TC2 alloy pipe was simulated, and the field variables of the pipe at different extrusion stages were analyzed simultaneously by using DEFORM-3D FEM. Then the friction coefficient was determined by fitting the calculated load to the actual one. and the effect of friction coefficient and half cone angle of die on the extrusion load was also discussed.%采用DEFORM-3D有限元法模拟了TC2合金管材的等温挤压成形过程,并对挤压过程中不同阶段的各种场量进行了分析,通过与实际生产对比确定了挤压摩擦因数,同时分析了不同的摩擦因数和凹模半锥角对挤压载荷的影响.
