英文摘要：

Based on a torsional-transverse coupling model of a 2K-H spur planetary gear, the equation formula of vibration energy of planetary gear transmission system was derived. The relationship between the parameter sensitivity of the planetary gear and vibration energy was analyzed. Potential energy and kinetic energy of the planetary gear that contains four planet gears were calculated under the operation conditions, in which the ring gear is fixed. The analysis results showed that the vibration energy of the planetary gear is mainly dominated by strain energy. It may safely draw the conclusion that the influence law of the planetary gear parameters on eigenvalues can be obtained from the variety of vibration energy of each component with the different order of vibration.
