| Abstract: |
| In this paper, deep grove ball bearing GB6206 has been chosen as research object, and the explicit dynamics analysis method in ANSYS/LS-DYNA has been used to study features of fault bearing which with a tiny pit in the inner ring raceway. In the process of building this bearing FEM, the following parameters have been well considered, such as boundary conditions, friction, contaction, loads and so on. Through simulation, the corresponding equivalent stress nephograms and acceleration of nodes on the inner ring raceway has been obtained. According to features of acceleration which occurs neighbor to fault pit, bearing's fault diagnosis has been realized. This paper provides a new way in monitoring bearing status and diagnosing fault of bearing. |
