摘　　要：阐述Hilbert变换的定义及解调原理。工程应用的结果表明,利用Hilbert技术从复杂的振动信号中解调故障的调制信息,进而判断出故障齿轮的部位,是一种可靠的故障诊断方法。The definition and demodulation principle of Hilbert transform are described. The result of engineering application shows that Hilbert technique can pick up the demodulated information of fault gear from complicated vibration signal, judge the position of fault gear, and it is an effective fault diagnosis method.
