摘要
基于动力学拉格朗日法推导了齿轮系统的特征方程,并对其固有频率和模态进行了分析计算。随后就行星齿轮的各阶固有频率对行星齿轮转动惯量和啮合刚度的灵敏度进行了具体计算分析,得到各阶固有频率随转动惯量和啮合刚度变化的变化规律,为下一步行星齿轮的动态设计提供理论指导。
On the basis of dynamics Lagrangian method the characteristics equation of gear system has been deduced, and an analytical computation was progressed upon its inherent frequency and modality. Soon after that by taking the each ordered inherent frequency of the planetary gear to carrying through the concrete computational analysis on the moment of inertia of planetary gear and the sensibility of the engagement rigidity. The variation law of each ordered inherent frequency that changes along with the variation of moment of inertia and engagement rigidity was obtained, thus provided theoretical guidance for the next stepped dynamic design of planetary gear.
