系统而完整地提出了处理变速机械弱时变响应信号的离散频谱多点平均幅值修正法的理论和方法 ,严格证明了该方法能精确地计算出平稳信号和频率微弱波动信号的幅值 ,能近似地计算出幅值和频率均微弱波动的信号的平均幅值 ,并应用这套理论成功地解释了频率微弱波动信号的幅值谱表现出较严重的“功率泄露”效应的原因
The theory and method of discrete multi-point average amplitude correction method for weakly varying time-varying response signals of variable speed machines are systematically and completely presented. It is proved that this method can precisely calculate the amplitude of stationary signals and weakly fluctuating signals, The average amplitudes of signals with weakly fluctuating amplitudes and frequencies can be approximated and the application of this theory successfully explains why the amplitude spectrum of weakly fluctuating signals of signals exhibits a more serious “power leak” effect
