Quantitative Fault Analysis of Bearings Based on ADAMS

Bearings have high transfer efficiency, versatility, good starting performance advantages make it become one of the most critical parts in rotating machinery, its main function is to support the mechanical rotator. Rolling bearing’s quality related to the operating status of machinery and equipment directly. In order to solve the problem of quantitative bearing fault diagnosis, a dynamic model of rolling bearings is established with ADAMS. Three kinds of fault vibration signal response of different sizes of the bearing outer ring were obtained. According to the time interval of bearing failure bearing double fault response can achieve quantitative analysis of bearing fault.
