【Abstract】 Considering the basic specific mechanisms,the rolling bearings fatigue life models are classified into three different types: statistical lifetime model,fracture mechanics based lifetime model and empirical lifetime model.The main life models of the rolling bearings are discussed and analyzed qualitatively,and the trend of the rolling bearing’s life theory is discussed in the end.更多还原
