Abstract

Investigation of thermal effects and the role of local abrasion in rubber friction processes K. Hofstetter, J. Eberhardsteiner and H.A. Mang Institute for Strength of Materials, Vienna University of Technology, Austria Abstract In this paper a contact model for thermo-mechanically coupled simulations of rubber friction processes is presented. Formulations are proposed for the friction coefficient, depending on pressure, velocity and temperature, and for thermal parameters for determination of the frictional heat generation and the heat conduction across the contact interface. All formulations are based entirely on macroscopic characteristics of the contacting solids. An experimental setup for the determination of contact parameters and for the validation of the presented contact model is described. Data measured at this setup are compared to numerically obtained results stemming from the application of the contact model in finite element simulations. Generally, good agreement is observed. 1 In
