首先给出了谐波小波时频剖面图检测含噪声信号的微弱奇异成分的方法 然后运用谐波小波时频剖面图方 法分析了碰摩故障仿真信号 最后利用该方法对多个实际汽轮机组动静碰摩故障的真实振动信号进行了分析研 究。结果表明, 谐波小波能够得到其它信号分析方法无法得到的特征, 有效识别机组的碰摩故障。(Harmonic wavelet time􀀁 frequency profile plot is introduced firstly in practice to identify weak singularity in a signal with noise clearly. With this method, emulational signal and vibration data of the rubbing of the large practical turbo-generator units are analyzed successfully, which prove that the method is effectively extract the rubb ing signal feature.)

级联积分－梳状(Cascaded Integrator–Comb，CIC)滤波器，是种高 效滤波器。它是一种线形相位FIR滤波器，由工作在高抽样率的级联理 想积分器和低抽样率的级联微分器组成,根据抗混叠和抗镜像的指标 确定所需的级联数目。 (Cascaded integrator- comb (Cascaded Integrator-Comb, CIC) filter, is the kind of high efficiency filter. It is a linear phase FIR filter, high sampling rate by the work in the cascade of an ideal integrator and a low sampling rate of the cascade differentiator formed, according to anti-aliasing and anti-mirror of the indicators to determine the number of required cascade.)
