Research Abstract

In one degree of freedom vibration systems with frictional surfaces, average amplitude of vibration increases and average frictional coefficients and specific wear rates decrease as a sliding velocity increases. During the frictional surfaces contact each other for long time, the average frictional coefficients and the specific wear rates decrease and the average amplitude of vibration increases. This trend is the same as that of the sliding speed fluctuating.
