Abstract：In order to obtain the ruler of thermal-mechanical coupling to residual stress on spline surface during the high speed cold roll-beating,the forming process of residual stress in the cold roll-beating surface layer under the action of thermal-mechanical coupling was analyzed.The action mechanism of thermal-mechanical coupling to residual stress was studied.Based on the constitutive model of 20 steel,the simulation analysis was conducted on the residual stress of surface during high speed cold roll-beating under the effect of thermal-mechanical coupling.According to the changing curve of rolling force and residual stress under different simulation parameters,it revealed that peek residual stress can be increased due to either feed rate or roll-beating speed enlarged.The increase of feed rate led to the whole roll-beating force larger,in contrast,the increase of roll-beating speed contributed to the decrease of roll-beating force and also affected the curve tendency.The study provided the basis of how to solve the problem of control the surface layer of residual stress on the spline during the process of high-speed cold roll-beating,which had great theoretical significance and engineering application value.
