Failure Analysis of the Bolt on the Compressor Cylinder Cover

Jingru Wang

Abstract

The fracturing reason of bolt for the compressor cover was analyzed.With OM and SEM,the fracture surface and metallographical microstructure were investigated and the factors related to material and mechanics were analyzed.We think that the method of estimating maximal pre-applied stress of the working bolt can provide a reference for preventing further fatigue fracture of boxter bolts.
