The Dynamic Properties of Planetary Transmission of Wind Power Growth Gearbox Considering Installation Constraints

Abstract

Abstract. The natural mode shape of planetary gear train is closely related to vibration and noise. It is valuable to study installation constraints of the planetary transmission, which is very important in the theoretical and engineering. A new method was proposed to study the influence of the planet carrier's different constraints on the planetary gear train's inherent vibration mode. The supporting stiffness of the planetary gear and the center member were considered respectively in the dynamic model of planetary gear train. The planet carrier constraint way simulation was realized through the support stiffness of different combination. A dynamic model with considering the planet carrier constraints was built to study the influence of different installation methods of the carrier on the natural vibration mode. The research indicates that the different installation way has a significant effect on the inherent vibration mode of planetary gear train.
