以某AT变速器行星轮系为研究对象,利用有限元法分析了行星架、齿圈和壳体的动态特性。并结合模态实验,验证了壳体有限元模型的准确性。建立了AT行星轮系动力学分析模型并进行了接触斑点实验,通过仿真与实验接触斑点结果对比分析得出,小太阳轮-短行星轮、长行星轮-齿圈齿轮副的啮合斑点基本一致且存在明显的偏载现象。通过导入柔性行星架、齿圈和壳体有限元模型得到了完整的AT变速器动力学模型,重点分析了行星架、齿圈、壳体柔性对行星齿轮传递误差、啮合错位量等啮合特性参数的影响,结果表明,壳体柔性和齿圈柔性变形对齿轮啮合错位以及传递误差的影响最为显著,行星架柔性影响次之。通过提高支撑轴承刚度、轴承预紧力和齿轮参数优化的方法,改善了行星轮系齿轮啮合特性,优化了行星轮系齿轮强度以及AT变速器NVH性能。
Taking the planetary gear train of an AT transmission as the research object, the finite element method is used to analyze the dynamic characteristics of the planet carrier, ring gear and housing, and the accuracy of the finite element model of the housing is verified by combining with the modal experiment. The dynamics analysis model of the AT planetary gear system is established and the contact spot experiment is carried out. Through the comparative analysis of the simulation and experimental contact spot results, it is concluded that the meshing spots of the small sun gear-short planet gear and the long planet gear-ring gear pair are basically the same and there is a significant partial load phenomenon. The dynamics model of the AT transmission is obtained by importing the finite element model of the flexible planet carrier, ring gear and housing, and the transmission characteristics of the planet carrier, ring gear and housing flexibility to the planet gears, and the amount of meshing misalignment parameters are analyzed. The results show that the flexible deformation of the casing and the ring gear has the most significant effects on gear misalignment and transmission errors, followed by the planetary carrier flexibility. By improving the support bearing stiffness, bearing preload and gear parameter optimization methods, the planetary gear train gear meshing characteristics are improved, the planetary gear train gear strength and the AT transmission NVH performance are optimized.
