电梯振动与噪声典型故障的分析及处理

Analysis and Overcoming of the Typical Faults of Elevator Vibration and Noise

结合实际工程中的一些振动与噪声典型故障案例，根据系统动力学理论，利用PMT和B＆K测试工具，分别采用时域振动分析法、频域振动分析法、时域噪声分析法、频域噪声分析法进行了具体分析。

According to system dynamics theory, using the PMT and B＆K test tools, taking the time domain vibration analysis method, the frequency domain vibration analysis method, the time domain noise analysis method and the frequency domain noise analysis method, the vibration and noise of elevator are analyzed respectively with the practical engineering cases,
