Fault diagnosis of fracture problems has always been a difficult point in fatigue analysis, and there is no good solution at present. Aiming at the nonlinear problem of fracture problems, this paper studies the pre-critical technology. According to the compressor cover local cracking problem, respectively by finite element analysis software MSC. Patran and Nastran to cover components were nonlinear analysis, through the comparison and fault diagnosis method of the fatigue damage final cover cracking reasons, the improving measures are put forward in this paper, the solution is verified the effectiveness of the improved reliability calculation..
