MECHANICAL FAILURE DIAGNOSIS IN UNSTEADY OPERATING CONDITIONS

Abstract

Abstract: To solve the problem difficult to diagnose which the traditional failure diagnosis method can’t solve in unsteady operating conditions, treating vibration signals of machinery in unsteady operating conditions are proposed by using instantaneous power spectrum (IPS) and genetic programming (GP), generating excellent symptom parameters GP-SP for failure diagnosis, and failure of machinery in unsteady operating conditions is diagnosed. The method has been applied to the failure diagnosis of rolling bearing.

Key words: Failure diagnosis, Genetic factor, Operating conditions, Power spectrum, Programming
