时域同步平均在振动信号分析中的应用

Average time domain synchronous method in gearbox fault diagnosis

时域同步平均可以有效过滤与旋转频率无关的噪声干扰。文中根据时域同步平均的原理,将旋转机械振动信号分为两组,进行时域平均处理对比研究,验证了时域同步平均方法的可行性。

Average time domain synchronous technique is commonly used to filter the noises in rotating machinery .Based on the time domain synchronization ,the vibration signals of a rotating machinery are divided into two groups for time domain average processing study to verify the feasibility of the time domain synchronous average method .
