Abstract

The dynamic simulation of infrared signature of the deep groove ball bearing (DGBB) was carried out based on ANSYS/LS-DYNA. A finite element model of the ball-raceway contact of the was established, and the slide friction between the ball and the raceway was considered as the main reason of heat generation, and the impacts of radial load, rotation speed and the coefficient of friction to the heat generation and the infrared characteristics of distribution were discussed in detail. The relative errors between the simulation results and the theoretical calculation value are less than 10%, which proves this simulation model is accurate and reliable.
