摘要
为研究扭转刚度对面齿轮四分支传动系统固有特性的影响,建立考虑扭转刚度和时变啮合刚度的集中参数系统动态力学模型,采用数值求解法,对动态力学模型的微分动力学方程进行求解,分析了扭转刚度对面齿轮四分支传动系统固有特性影响。结果表明:面齿轮四分支传动系统的固有频率具有明显的四重频现象;刚度在0. 4×109～0. 8×109N·mm-1变化时,固有频率的变化幅度较大,扭转刚度大于0. 8×109N·mm-1时对系统前10阶的固有特性的影响较小。可以为进一步进行面齿轮四分支传动系统的结构优化设计提供理论依据。
In order to investigate the influences of torsional stiffness inherent characteristics of face gear transmission system of four branches,the establishment of torsional stiffness and dynamic mechanics lumped parameter system model considering the meshing stiffness,the numerical solution method,dynamic differential equations of dynamic mechanics model for analysis of torsional stiffness inherent characteristics of face gear transmission system of four branch effect.The results show that the natural frequencies of the face gear four branch drive system have obvious four coincidence frequency phenomena;Stiffness in 0.4×10^9 to 0.8×10^9N·mm^-1 changes,the natural frequency changes greatly,the torsional stiffness in the 0.8×10^9N·mm^-1 value on the inherent characteristics of the first 10 order of the impact of small.It can provide a theoretical basis for further optimizing the structure design of the face gear four branch drive system.
