摘要：

Resonance-demodulation　technology　has　been　studied　to　detect　the　micro　shock　pulses　induced　by　the　early　fault　of　rolling　bearings.　The　spectrum　analysis,　and　the　software　and　hardware　resonance　demodulation　technology　have　been　adopted　separately　to　analyze　the　pitting　fault　on　the　outer　ring　of　rolling　bearing.　The　results　have　indicated　that,　the　resonance　demodulation　technology　can　detect　the　fault　features　of　early　micro　shock　pulses,　and　the　fault　features　detected　by　the　hardware　resonance　demodulation　technology　are　more　accurate　than　the　software　resonance　demodulation,　and　the　hardware　resonance　demodulation　technology　is　a　effective　method　to　detect　the　early　cracking　and　pitting　fault　features　of　rolling　bearings.
