Finite Element Analysis and Experimental Study on Failure Rolling Bearing

Abstract

As the most important component of moving parts in the wheel set system, the rolling bearings’ performance is the key to the safety of locomotive running. In this paper, the finite element model of rolling bearing with fault of inner ring stripping was established in ABAQUS, the first twenty orders of natural frequency and mode characteristic was analyzed. The highest frequency was used as the center frequency of the band pass filtering in the process of resonance demodulation and this technique was validated with simulation. Then fault vibration signal of rolling bearing was collected using wheel set running-in test bench and was analyzed with this method, the comparison proved that the simulation and test results basically tallied.
