摘要
Rolling bearings are applied in most machinery, and their health status has an impact on the accuracy, stability, and reliability of mechanical equipment. The existing fault diagnosis methods are carried out damage experiments on physical equipment. However, the data acquisition is insufficient, the cost is high. A basic framework of bearing fault simulation modeling strategy is proposed. First, a three-dimensional mode is established according to the geometric size of the physical entity. Then, a virtual simulation model of equipment is constructed using the finite element analysis method. Finally, a virtual fault is injected into the virtual simulation model to generate fault characteristics through model simulation. In the case study, the generation method of bearing fault feature is established. The results show that the model is reliable in generating bearing fault characteristics.
