【摘要】 从静力学和动力学两方面介绍行星齿轮传动均载研究现状。静力学研究主要采用等效弹簧模型法和有限元与面积分技术相结合的接触力学法,研究制造误差和弹性变形等对均载性能的影响。动力学研究主要采用集中参数法、有限元与集中参数混合建模法、有限元与面积分技术相结合的多体接触动力学建模法,研究时变啮合刚度、齿侧间隙、齿轮误差等所引起的动载荷对均载性能的影响。更多还原

【Abstract】 The state of the planetary gear transmission load share behavior research is introduced in terms of statics and dynamics. The influence of manufacturing error and elastic deformation on the static load sharing behavior is studied by the equivalent spring model and the combined surface integral and finite element solution for contact problem. The influence of dynamic load induced by the timevarying meshing stiffness, the backlash in tooth and the gear error on the load sharing behavior is studied by the lumped parameter model, the hybrid finite element/lumped parameter model and the combined surface integral and finite element solution for multi-body contact dynamics更多还原
