Algorithm for restoration of friction power in drum brake device with a layer from the compositional material on temperature data

A quasilinear two-dimensional mathematical model of the thermal process in a drum braking device is considered, taking into account the rotational motion of the brake cylinder. The basic heat conduction equations and the algorithm for solving by method of conjugate gradients of the boundary inverse heat conduction problem to restore the friction power between the brake pad and the cylinder on temperature data are given.
