Modeling and Computer Simulation Analysis of Bearing-Gear System

As the vibration form of bearing gear system is very complex, it is the coupling of different vibration. In particular, the stiffness of the system changes with time, contact impact, manufacturing and installation errors, which has a great impact on the structure. It is difficult to get accurate analysis results only through theoretical analysis. The computer simulation analysis can not only be used as the preparation of the actual test, but also can replace the traditional test to a certain extent. In this paper, the bearing gear system model is established, the static analysis and modal analysis of the system are carried out by using the finite element method and on the basis of the analysis of the bearing gear system, suggestions for structural improvement are put forward.
