PS37 セラミック軸受軌道の転がり接触によるき裂進展解析

Abstract

Crack propagation analysis for ceramic bearing orbit under rolling contact was performed using finite element analysis and fracture mechanics. A fracture-mechanical approach was proposed for evaluating stress intensity factor, and its appropriateness was examined by the results of the analysis and the experiment. It was found that the analysis results nearly agreed with the experimental results, which verified the fracture-mechanical approach.
