摘要： 以含有太阳轮减重孔、齿圈固定孔、柔性系杆的行星轮系为研究对象，基于ANSYS软件，建立了考虑实际结构的修形行星轮系有限元模型.基于该模型，研究了齿顶修形以及减重孔、齿圈轮缘厚度、柔性系杆等齿轮结构对行星轮系时变啮合刚度的影响.研究结果表明:齿顶修形改变了啮合刚度曲线的形状和数值大小;减重孔增大将导致啮合刚度减小而齿圈支持率变大使啮合刚度增加;同时，系杆越柔，行星轮系啮合刚度波动越小.研究结果可为实际生产中考虑修形的行星轮系设计提供理论依据.

Abstract: Taking the planetary gear system as the research object， which contains lightening hole of sun gear， pin support of ring gear and the flexible carrier arm， a finite element model of planetary gear system with gear tip relief was established on the basis of ANSYS software. Based on the model， the influence of the gear tip relief and gear structure， such as lightening hole of sun gear， the rim thickness of ring gear and the flexible carrier arm， on the mesh stiffness was analyzed. The results show that the gear tip relief changes the shape and value of the mesh stiffness curve. Mesh stiffness decreases with the increase of lightening hole size. However， with the increase of the backup ratio of ring gear， the mesh stiffness increases gradually. Meanwhile， the more flexible the carrier arm is， the smaller the gear meshing stiffness fluctuates. The research results may provide a theoretical basis for the design of planetary gear system considering gear modification in actual production.

Key words: planetary gear system, mesh stiffness, gear tip relief, gear structure
