摘　　要：为了有效地获取滚动轴承具有可比性的加速寿命试验数据,利用已有加速寿命试验相关标准,结合实际滚动轴承加速寿命试验设计和实施中积累的经验,深入分析滚动轴承加速寿命试验过程中遇到的各种问题,提出一套完整的滚动轴承加速寿命试验方法。该方法对相关标准没有涉及的试验前检查、试验条件一致性分析和试验数据的处理方法进行了补充并对加速寿命试验进行深入分析,形成完整的滚动轴承加速寿命试验解决方案,可以有效地指导滚动轴承加速寿命试验的设计和实施。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.
