摘要
Abstract
The study based on the frequency spectrum analysis shows that the main reason of vibration fault for gearbox is the excitation source generated in the process of gear mesh. In order to research the vibration characteristics of gearbox bolts, a finite element model was established under the simulate conditions. The results show that the third order natural frequency of bolt and the master vibration frequency of gear box were similar,and vibration resonance is the main reason of bolt fracture. The rate of bolt fracture is reduced effectively through the analysis method.关键词
