复合行星齿轮传动系统虚拟样机仿真研究
Research on Virtual Prototype Simulation of Compound Planetary Gear Train Sets
摘要
Abstract
Based on the typical structure of Ravigneaux compound planetary gear train sets, the transmission ratio and meshing frequency of the system were analyzed. In order to obtain the changing patterns of contact force of Ravigneaux compound planetary gear train sets, a 3-D solid model of the sets was established by SolidWorks software and the virtual prototype of the system was built based on ADAMS software. The computation method for contact force of gear meshing was introduced based on Hertz theory. The transmission ratio of the system was verified. The changing pattern and the spectrum characteristics of the synthetic contact force between small sun gear and short planet gear, that of x direction and y direction were simulated. The simulation results show that the ampltude of contact force fluctuated obviously, which had notable periodic property. The contact force of x direction and y direction has the same frequency spectrum and phase difference of 90°. The rotational frequency and frequency multiplication of 1 to 7 of meshing frequency are in the frequency spectrum of contact force,which have explict modulating characteristics. The virtual prototype researches of Ravigneaux compound planetary gear train sets can provide some references to improve the system dynamic characteristics and achieve dynamic design.关键词
