摘要
首先根据摆线钢球行星传动的受力状态,计入各啮合副之间的载荷分布及其变化规律,建立了摆线钢球行星传动系统的平移—扭转耦合动力学模型;然后通过分析各构件间的相对位移关系,推导出了系统动力学方程,进而通过求解其特征值得到相应派生系统的各阶固有频率和主振型,从而揭示了系统的固有特性;最后分析了摆线钢球行星传动的主要结构参数对固有频率的影响。
Firstly,according to the loads distribution and variation, a translational--torsional cou- pling dynamics model of a cycloid ball planetary transmission system was established. Secondly, by analyzing the relative displacement relationships of each component, the dynamics equations of system were derived. And then, the natural frequencies and principal modes of the derivative system were present by solving the associated eigenvalue problem. Finally;the main structure parameters were se- lected to analyze the influences on the natural frequencies.
