Vibration of Sliding Contacts

Introduction

The rubbing of two solid bodies often results in vibration and acoustic emission. The exact nature of this behaviour can be strongly influenced by the frictional characteristics of the contact pair. Although this phenomenon is commonplace and has some important consequences, it generally remains poorly understood; either because of a lack of detailed information concerning the friction itself or how this affects the dynamic response of mechanical systems.

As examples of the disparate fields of physics where sliding contact vibrational phenomena are important, our tactile perception of objects is influenced by any sound, vibration or intermittent motion that occurs when they are touched. The quality of the sound produced by a bowed musical instrument depends crucially on the nature of the friction between the bow and the strings. In dynamic mechanisms such as brakes, gears, bearings and turbines, frictionally-excited vibration is usually undesirable since it can generate excessive noise. Vibration can also lead to the accelerated wear of particular components through, for example, fretting fatigue and can also result in premature machine failure. In this context, the monitoring of a machine’s acoustic emission provides a diagnostic tool that can be used to reduce the likelihood of such events occurring. Finally, by way of contrast, it is noted that the deliberate imposition of vibration can, in certain circumstances, be used to reduce friction.

The intention of this one day meeting is to be of general interest to those working in the fundamentals or applications of tribology or vibration research. Common themes are the desire to control vibration by informed modification of the friction (or the system dynamics), or to use measurements of the vibration or acoustic emission to give information about the frictional properties or condition of the contact pair. The meeting will consist of a number of invited talks and will concentrate on areas where particular progress has been made.
