摘　　要：针对轴承内圈综合力学性能及疲劳特性要求较高等问题,以深沟球轴承内圈为研究对象,对其辗压成形原理进行分析;运用专业有限元软件Simufact建立其连辗压成形有限元模拟仿真模型,对其在不成形率下的等效应力、等效应变变化规律及不同辗压成形工艺参数下的等效应力、等效应变变化规律进行仿真分析。有限元模拟仿真结果表明:随着辗压成形率增加,等效应力及应变呈现逐渐增加的趋势,且在不同的成形率下,等效应力、应变大小及分布位置不同;随着辗压温度及进给速度的增加,等效应力及应变呈现逐渐减小的趋势;随着摩擦因数的增加,等效应力及等效应变都呈现先减小后增加的趋势;该研究为轴承内圈辗压成形模具设计和工艺参数优化提供了理论依据。For the problems of the high requirements for the comprehensive mechanical properties and fatigue characteristics of bearing inner ring,the deep groove ball bearing inner ring has been taken as the research object,and the principle of rolling forming has been analyzed,and the finite element simulation of continuous rolling forming have been established by using the special finite element software Simufact.The models have been simulated and analyzed under the equivalent stress, equivalent strain variation law and the equivalent stress and equivalent strain variation under different rolling forming process parameters.The finite element simulation results show that the equivalent stress and strain show a trend of increasing with the increase of the rolling forming rate,and the equivalent stress,strain and distribution position are different at different forming rates;With the increase of feed rates,the equivalent stress and strain show a decreasing trend.With the increase of friction coefficient, the equivalent stress and equivalent strain first decrease and then increase.The research provide the theoretical basis for the design of the bearing inner ring and the optimization of the process parameters.
