TA18管材三辊冷轧三维有限元模拟

3D Finite Element Simulation of Three-Roller Cold Rolling Process

应用有限元软件Msc.Marc对TA18管坯三辊冷轧过程进行了三维有限元模拟,获得了三辊冷轧管过程中瞬时变形区接触规律、坯料质点在轧制过程中的运动轨迹、摩擦力和剪应力的周向分布以及金属管坯从进入变形区到出变形区各阶段的变形规律。

The instantaneous contact rules at the deformation zone during three-roller cold rolling process, the motion trace of blank particles during rolling, the circumferential distribution of friction force and shear stress and deformation rules of metal tube at the each stage from going into to out of the deformation zone are obtained by analysis.
