Analytical Model for Sliding Behavior of Teflon‐Stainless Steel Interfaces
Publication: Journal of Engineering Mechanics
Volume 116, Issue 12
Abstract
An analytical model is proposed to describe the interfacial sliding characteristics of Teflon and stainless steel based on experimentally observed quasi‐static and dynamic sliding characteristics. The effects of normal pressure, sliding distance, normal pressure history, sliding velocity, sliding velocity history, normal pressure rate, sliding work, etc., are included. The dependence of the dynamic friction force on both the normal pressure and the sliding velocity is uncoupled in this formulation. The dynamic friction force is determined by multiplying the quasi‐static friction force by an amplification factor. The amplification factor is a pure function of sliding velocity. The proposed model is validated by a quasi‐static test and a dynamic sliding test. In the quasi‐static verification test, the applied normal contact pressures are changing during sliding. For the dynamic validation test, the Teflon‐stainless‐steel interfaces are subjected to varied normal pressures and sliding velocities. Very good agreement between the predicted and the experimental results is obtained.
