| Abstract: | This paper discusses the model of gear and the relation of vibration and noise according to the simplified vibration model of final drive in automobile,presents a monitoring system based on virtual instrument.The system has three functions: acquiring acceleration signals of vibration,analyzing power spectrum and diagnosing final drive fault.It can be used to assembly line to detect the early fault of final drive so as to repair in time and avoid the subsequent fatal damage.Furthermore it can not only denoise but also improve the quality and the transmission performance of final drive. |
