| 摘 要： | 根据Ravigneaux式复合行星齿轮传动系统的典型结构,分析了系统的传动比与啮合频率。为获得Ravigneaux式复合行星齿轮传动系统轮齿接触力的变化规律,运用三维CAD软件SolidWorks建立了系统的三维实体模型,以ADAMS软件为平台建立了系统的虚拟样机模型。给出基于Hertz接触理论的齿轮啮合传动时轮齿接触力的计算方法,验证了系统传动比，对小太阳轮与短行星轮啮合的综合接触力、x方向接触力和y方向接触力的变化规律及其频谱特性进行仿真研究。仿真结果表明,接触力的幅值波动显著,具有明显的周期性。x方向接触力和y方向接触力具有相同的频谱特征,相位相差约90°。频谱中出现小太阳轮的旋转频率和系统啮合频率的1至7倍频率成分,存在明显的调制特性。通过对Ravigneaux式复合行星齿轮传动系统虚拟样机仿真的研究,为改善系统动力学特性以及实现系统的动态设计提供了指导依据。

| 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. |
