| Abstract: | Gearbox is the necessary general components in mechanical equipment,which is also the component with frequently failures.Gear failure is an important factor which would lead to the faults of the gearbox.Therefore,it is of great significance to develop new technology for the fault diagnosis of gearbox.The optical measurement system based on Polytec laser Doppler vibrometer is built up to pick vibration signals and second generation wavelet is used to extract the fault features.The goal of fault diagnosis is realized,which can be applied to the foreknowledge and intelligent service of the gearbox faults. |
