Abstract

Automotive brake and clutch systems experience temperature and contact pressure variation due to frictional heat generation. Due to geometrical complexity and the coupled thermo-mechanical nature of this class of problems, direct finite element simulation is found to be computer-intensive. This paper explores a more time-efficient method that can be used to obtain the transient solution for the unperturbed clutch and brake system based on an eigenfunction expansion and a particular solution. An approximate solution can also be sought based on the same method in which only a subset of the eigenfunctions are used.
