摘要：

The nonlinear problem of thermoelastic contact of a rotating shaft with a rigid bush fixed to the base elastically (springs) is investigated using both Laplace transform and perturbation methods. A friction coefficient is assumed to be a nonlinear function of a relative velocity, The solution to the problem is reduced to the system of nonlinear differential and integral equations. Zones of steady-state solution stability and friction self-excited oscillations existence are established, The numerical analysis is carried out and some important conclusions are given.
