在具有摩擦表面的单自由度振动系统中,随着滑动速度的增加,平均振动幅值增大,平均摩擦系数和比磨损率减小。摩擦表面长时间接触后,平均摩擦系数和比磨损率减小,平均振动幅值增大。这种趋势与滑动速度波动的趋势相同。
英文摘要
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.
