Research on accelerated life test for rolling element bearings

In order to obtain valid and comparable data from ALT for rolling element bearings, almost all problems which may appear in the process of ALT for rolling element bearings were investigated comprehensively. Then an orbicular method of ALT for rolling element bearing was proposed based on the existent standardizations of ALT for rolling element bearings and experience accumulated in the process of actual design and implementation. The method has complemented such omissions as pro-experiment checking, uniformity verification and signal processing which the existent standardizations and traditional life test schemes have not considered, and then formed an integral solving scheme of ALT for rolling element bearings. This scheme can be used as a guide for the design and application of ALT for rolling element bearings.
