Single Pass Rub Phenomena—Analysis and Experiment

Abstract

This paper describes an experimental and analytical investigation of the temperatures and deformations which occur during a single traverse of a steel blade tip over a flat, smooth, fully-dense copper surface. Experimental work was carried out on a pendulum-type test device, with forces, rub energy, surface temperature, and residual deformation being determined for each single-pass rub test. An analytical model was developed for studying the thermal and mechanical factors influencing surface temperature in these single-pass rubs. The analytical surface temperature predictions were verified by the experimental results.
