Abstract

To address thermal failure in wet friction pairs of mechanical transmissions, this paper develops a contact thermodynamic model for incorporating elastohydro-dynamic lubrication(EHL) theory and accounting for elastic deformation effects at rough interfaces. The validity of the model is verified by analyzing the temperature field and friction coefficient using the friction and wear tester. Furthermore, this paper investigates the temperature field characteristics in wet friction pairs by focusing on the laser-manufactured circular micro-textured interface of the friction element. Based on simulation results of local pressure distribution, local surface topography, and local temperature distribution, the study specifically discusses the influence of average surface pressure, sliding speed, oil temperature, micro-texture radius and depth on pressure and temperature. The results indicate that the model has high accuracy, with an average error is around 4 %. The maximum interface temperature increases by only 9.44 % and 0.30 % with the increase in micro-texture radius and depth, respectively, demonstrating that the micro-texture depth and radius contribute to enhanced heat dissipation at the interface.

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
