Effect of convective cooling on temperature and thermal stresses in disk during repeated intermittent braking

Resumo

A numerical solution of the heat-friction problem for a brake pad–brake disk system during repeated intermittent braking has been obtained using the finite-element method. The obtained temperature field has been used to study the thermal stress state of the disk. A numerical analysis has been carried out for a metal-ceramic pad–cast iron disk friction pair during ten intermittent brakings. The effect of the coefficient of the coefficient of heat transfer on the temperature, the stress tensor components, and the Huber–Mises–Henky stresses on the working surface of the disk has been investigated.
