摘要
对金属往复滑动摩擦噪声进行了声学和动力学测量 ,通过对声压级和加速度进行时间历程波形分析、功率谱分析 ,确认摩擦噪声是由参加相对滑动的摩擦副的 1个或 2个部件的振动辐射所产生 。
Measurements of noise and vibration induced by friction were performed. The time history records of sound pressure level and vibrational acceleration and their power spectral densities were analyzed. The results show that the friction-induced noise was associated with the vibration of mechanical parts of the friction system. 45 and GCr15 are used in the test.
