摘要
分析高精度FA传动的运动原理及结构特点,建立高精度FA传动的系统动力学模型。根据拉格朗日方程推导出系统的运动微分方程。推导各主要部件的当量质量及啮合刚度,将求得的当量质量、刚度组成质量矩阵和刚度矩阵,进而求解振动方程得到系统的固有频率,同时探讨了各主要部件的参数对系统固有频率的影响。
System dynamics model of high-precision FA-transmission was built based on analysis of the motion principle and structure characteristics. The differential equation of the system motion was derived according to the Lagrange equation. The equivalent mass and meshing stiffness of the main components were developed which formed the mass and stiffness matrices, and then the vibration equation was solved to get the natural-frequency of the system which was influenced by the parameters of the main components.
