Abstract：

According to the characteristics of tapered roller in the helical rolling process and the analysis of stress state, a traditional Lemaitre damage model was improved by considering the difference of damage growth under positive and negative hydrostatic pressure stress state and the influences of strain rate and deformation temperature on damage growth. Then, the modified model was implemented in the FE model of helical rolling for tapered roller by the secondary development technology of SIMUFACT, and the damage prediction model of helical rolling for tapered roller was established. At the same time, the damage prediction model of helical rolling for bearing steel ball was also set up by the above technology, and the experimental results were compared with literatures to verify the reliability of modified Lemaitre damage model. The simulation results show that the large damage zones are located in the axial centre of connecting neck and near the axial centre of connecting neck in the helical rolling process of tapered roller, and the central damage in small end of tapered roller is larger than that in big end.
