摘　　要：根据曲轴圆角滚压加工过程,采用ANSYS/Workbench仿真软件建立相应的有限元模型,通过改变滚压力和滚压圈数对比分析曲轴滚压后的应力和应变分布状况,为曲轴圆角滚压参数的设置提供参考.仿真结果表明,合理的滚压力可以有效地提高滚压后产生的残余压缩应力和应变,合理的滚压圈数可以在保证有效压缩应力和应变的情况下减少滚压圈数,提高加工效率.Based on the motion of the crankshaft and roller in the period of fillet rolling ,a finite element model for crankshaft fillet rolling processing was built with ANSYS/Workbench .Researchers investigated the stress and strain distributions of crankshaft with variable force and number of turns . The results provided references for technological parameters of fillet rolling .The simulations reveal that appropriate control of force could increase residual stress and strain of crankshaft effectively .In addition ,on the premise of effective stress and strain ,appropriate number of turns reduced cylinder number and increased the manufacture efficiency .
