【Abstract】 This paper applies virtual instrument technique to mine mechanical fault diagnosis, and exploits a hoister gearbox-testing system based on Labview. Making use of precise diagnosis of the measuring point of the hoist with the higher vibrational intensity on the basis of simple diagnosis, through the Amp. Spectrum analysis of the vibrational acceleration signal, the location and cause of the mine hoister gearbox fault are diagnosed accurately, and deterioration factor shows quantitatively the development of abrasion after five months.更多还原
