Frictional heat accumulation at cyclically rolling-sliding contacts with consideration to time-dependent contact pressure

Abstract

A finite element model is proposed for analyzing the frictional heat accumulation at high-speed rolling-sliding contacts. The moving frictional heat flux as a function of the time-dependent contact pressure is applied cyclically on the contact surface. The convectional heat boundary is considered in non-contact region. The transient temperature changes on the contact surface are calculated, which is validated against analytical calculation results by employing the Fourier transform method. The frictional heat accumulation effect and equilibrium-state temperature are obtained during cyclically rolling-sliding contacts.
