Abstract
Considering the radial load and rotational speed of bearing, the finite element (FE) model for dynamic contact of deep-groove ball bearing was established by the software — ANSYS. Based on explicit dynamic finite element method, the nodal displacement, velocity of rolling bearing and stress of rolling element were obtained. Through calculating, it could be seen that the maximum velocity was shown at the contact point between the rolling element and the inner ring, while the minimum velocity was shown at the contact point with outer ring. The maximum equivalent stress and shear stress of the bearing were also occurred at the contact point of raceway, and the inner ring was bigger than the outer ring. The finite element simulation of the motion process for deep-groove ball bearing had a guiding significance to the research of dynamic load between the rolling bearing components as well as the dynamic characteristics of rolling bearing.
