Thermal diagnostics of friction in the system of sliding bearings at low rotation speeds of a common shaft

Abstract

The problem of the thermal diagnostics of friction in the system of sliding bearings with a low rotational speed of the common shaft has been considered in which it is necessary to take into account its motion in the mathematical model of the thermal process in the system. It has been proposed to numerically solve the inverse problem of defining the functions of frictional heat generation by the temperature data in stationary bushings by the method of iterative regularization with a fairly small time step. Computational experiments have shown that the error of restoring the functions of frictional heat generation is commensurable with the accuracy of initial data setting.
