Russian Engineering Research Aims and scope

Abstract

A quasi-three-dimensional thermal mathematical model is proposed for a slip bearing made of polymer composite, in which with the shaft’s cross section varies over its length. The algorithm proposed for solving the inverse boundary problem permits the derivation of the frictional torque from temperature data. Numerical calculations demonstrate the efficiency of the algorithm and its robustness with respect to errors in the temperature measurements. The practical applicability of this method is confirmed experimentally.
