Thermal Stressed State of a Disk in the Process of Multiple Braking

Abstract

On the basis of the finite-element method, we propose a mathematical model of frictional heating of a disk in the process of multiple braking. We obtain the numerical solution of the axisymmetric initial boundary-value problem of heat conduction and the boundary-value problem of quasistatic thermoelasticity for a disk periodically heated on the friction surface by a heat flow whose intensity is proportional to the specific power of friction. The numerical analyses of temperature and temperature stresses in the process of multiple braking are performed for a disk made of cast iron and a cermet pad.
