Аннотация:In the paper, the initiation of thermoelastic instability under unsteady friction of anisotropic disc samples is considered. This process takes place during the operation of high-load braking systems in aviation and railway transport, special-purpose clutches for vehicles, and in other mechanisms. The instability leads to overheating of the friction surfaces, increased wear, and instability of the friction torque. The mutual influence of wear, friction-induced heating, and elastic deformations of the friction surface is modeled by a finite difference method. The process of friction and wear of discs is studied, taking into account the history of a series of braking actions. The annular pattern of the surface pressure and temperature distribution is considered and the influence of the emerging instability on the wear of the disc surface is determined.
