摘要：
In order to investigate the influence of the bolt constraint parameters on the dynamic characteristic of the planetary gear transmission(PGT) system with fuselage excitation, a dynamic model of the PGT system with flexible ring gear is established with the consideration of time-varying meshing stiffness with meshing phase, manufacturing error, installation error, fuselage excitation and bolt constraint. The Newmark-beta method is used to solve the dynamic model, then the dynamic load coefficient and load sharing coefficient is obtained. The results indicate that the parameters of the bolt have effects on the dynamic performance of the PGT system. Reducing the bolt number can can help to improve the dynamic load performance and load sharing performance of the system when bolt stiffness is small. Moreover, reducing bolt stiffness can also improve the dynamic load performance and load sharing performance of the system effectively.
