振动分析广泛应用于机械诊断中，并且Wigner-Ville分布也已在机械状态监测的许多应用中实施。与以前的应用相比，本文研究了声信号是否可以有效地用于检测齿轮箱中的各种局部故障，使用平滑的伪维格纳-维尔分布。对断齿、裂纹和局部磨损三种局部故障进行了仿真。将声信号的结果与振动信号的结果进行了比较。结果表明，声信号是非常有效的早期检测故障，并可能提供一个强有力的工具，以指示齿轮箱的各种类型的进展性故障。(C)北京：科学出版社.
Vibration analysis is widely used in machinery diagnostics and the Wigner-Ville distribution has also been implemented in many applications in the condition monitoring of machinery. In contrast to previous applications, this paper examines whether acoustic signal can be used effectively to detect the various local faults in gearboxes using the smoothed pseudo-Wigner-Ville distribution. Three types of progressing local faults, broken tooth, gear crack and localised wear, were simulated. The results from acoustic signals were compared with vibration signals. The results suggest that acoustic signals are very affective for the early detection of faults and may provide a powerful tool to indicate the various types of progressing faults in gearboxes.
