摘要
大型曲轴的全纤维成形工艺是保证曲轴能够在复杂的应力状态下正常工作的一种有效的工艺方案。由于其成形过程复杂，变形过程中的应力场和应变场很难用实验方法确定。本文基于ＡＮ－ＳＹＳ工作平台，利用开发的三维有限变形弹塑性有限元程序，并利用开发的三维网格重划功能模块，模拟了曲轴的ＴＲ法成形过程，得到了曲轴在成形全过程中的应力场、应变场以及载荷位移曲线，为制定合理的成形工艺方案，优化模具设计，提高成形质量。
TR upsetting process,an effective technology which ensure the continuous fibers in the forming process of heavier crankshaft,is important for the crankshaft to work well under complicated stress state.But it is very difficult to obtain the distribution of stress and strain of its complex forming process with the common experiment method.Based on the ANSYS software,with the developed 3D finite deformation elasto-plastic FEM software and the remeshing system,the TR upsetting process of crankshaft is simulated,and the distribution of stress and strain,the forcedisplacement curves are given.Those provide the possibility to design the optimum forming technology and die geometry dimension,improve the forging quality and extend the die life.
