Empirical Mode Decomposition (EMD) is introduced to replace time synchronous averaging of gearbox vibration signal.
探讨了应用经验模态分解代替时域同步平均分析减速器振动信号的方法。
The influencing rules on Time Synchronous averaging signal are achieved by Phase Error Accumulation Factor, component order and averaging number.
研究了相位误差累积因子、信号分量阶次和平均段数等参数对时域同步平均信号幅值的影响规律。
Time domain synchronous averaging can reduce the signal not coherent to rotation frequency effectively, and extract the repetitive signals directly related to machine operation condition.
而时域同步平均可以有效衰减与回转频率无关的干扰，提取与工作状态直接相关的周期信号。
