Abstract

The engagement of clutch system is a typical dynamic coupled temperature-displacement process which contains two or more sliding surfaces involved in frictional contact. This process influences evidently the thermal fatigue, noise and vibration of the clutch system. This effect can be more remarkable if the temperature distribution over the clutch disk is not uniform.

This thesis is organized into five chapters:

The first chapter is an introduction which reviews the background and previous work of thermoelastic instability and finite element analysis of clutch system and disk brake.

A parametric analysis of TEI (thermoelastic instability) is elaborated in the second chapter. A software package named "hotspotter" is used as a numerical tool. The objective of this chapter is to find the effect of geometrical dimension and the properties of material on TEI.

In the third and fourth chapters, several FEA (finite element analysis) models are developed by using ABAQUS to evaluate the thermomechanical processes in the frictional interface.

The fifth chapter is the summarization of the entire thesis.
