Then an orbic lar method of ALT for rolling element bearing was proposed based on the existent standardizations of ALT for rolling element bearings and experience acc m lated in the process of act al design and implementation. The method has complemented s ch omissions as proexperiment checking, niformity 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 sed as a g ide for the design and application of ALT for rolling element bearings. Key words: rolling element bearing; accelerated life test; niformity verification; accelerated model; accelerated coefficient , , , [ 1] 1967 , , , :
