摘要：
We propose a three-layer model of the process of braking. To determine the contact temperature and wear, we use an exponential dependence of the friction factor on temperature. By using the Laplace integral transformation with respect to time, we reduce the problem under consideration to a system of nonlinear Volterra-type equations. The results of numerical evaluation of the braking time, time of attainment of the maximum temperature, maximum contact temperature, and wear are presented in the graphic form.
