Study on friction characteristics between two bodies under vibration working case

Abstract

This paper mainly focuses on vibration friction and discusses the dynamic characteristics of the friction under vibration working case. Many practical projects have already proved that under vibration working case, the friction coefficient and the friction force among work pieces and materials can be reduced obviously, and the wear and tear of the parts of machine can be obviously lightened, and the work efficiency can be improved greatly. In this paper, the influence on sliding friction of vibration both parallel and perpendicular to the sliding direction has been studied. Models for friction characteristics between two bodies under longitudinal and transverse vibration working case are set up. On the basis of these models, longitudinal vibration produces greater reduction in friction than transverse vibration at the same amplitude and frequency. © 2011 Springer-Verlag.
