Abstract

This paper shows a thermal and tension analysis of a brake disc for railway vehicles. The FEM (Finite Element Method) was used to carry out the analysis. The analysis deals with one cycle of braking – braking from maximum velocity to a standstill, cooling off faze and then accelerating to maximum velocity and again braking to a standstill. This case of braking represents a part of a railway working conditions. The main boundary condition in this case was the entered heat flux on the braking surface, the centrifugal load and the force of the brake clamps. One type of disc was used - with permitted wearing.
