Abstract:
During a minibus's practical road driving and engine test rig test for vehicle and engine reliability, the phenomenon of generator compressor bracket fracture appears and leads the generator compressor crankshaft belt rupture. It seriously affects the vehicle's operation performance. The article carries through engine test rig test and analysis, using frequency and spectrum technology to identify the bad vibration source combining FEA. It also researches vibration's occurrence, formation, propaganda and fracture mechanism. Based on this, the authors put forward countermeasure, which improves the dynamic characteristic of the system, decreases the vibration intensity and avoides the fracture of bracket and belt.
