Analyzing Cavitation Caused by Metal Particles in the Transaxle: Application of High Quality Assurance CAE Analysis Model

This paper focuses on a strategic improving quality of “high quality assurance CAE (computer aided engineering) analysis model” to be used in development design. The authors present a case of transaxle oil seal leakage in automotive drive trains, a technical reliability problem that generates bottlenecks for auto manufacturers around the world. The application of this model is used to analyze cavitation caused by the metal particles (foreign matter) generated through transaxle wear. This analyzing method primarily uses numerical simulation (CAE) to clarify the technological mechanism generating oil leaks as a result of foreign metallic substances entering oil seals in the drive train. Quality improvement using this CAE analyzing method was verified by successfully applying it to the technological problem of development design bottlenecks at auto manufacturers.
