Abstract
The calculation scheme of a maximum temperature in a braking system composed of three discs with the same dimensions and thermophysical properties of materials was developed. Both a thermal sensitivity of the material of the discs and the roughness of the friction surfaces were taken into account. Based on the Chichinadze's hypothesis, the maximum temperature attained on each of two contacting friction surfaces of the discs, was found from the sum of the mean temperature on these surfaces and the flash temperature. The comparison of the maximum temperature calculated using the finite element method (FEM) at the solution of nonlinear axisymmetric thermal problem of friction with temperature determined from the analytical solution of the one-dimensional problem at the constant thermophysical properties of material of the discs was carried out.
