摘要
基于部件模态建立多柔体系统的线性化动力学方程,通过特征分析及与ANSYS有限元分析软件计算结果相比较,表明结果是可行的。在此基础上,研究了中心刚体和柔性附件的相对质量特性对多柔体系统非约束固有频率的影响。
Based on the component modes, the linear equations of the flexible multibody system are established. The unconstrained frequencies are calculated through eigenvalue analyzing of the derived linear equations. The comparison between the results of the equation and ANSYS shows the results are acceptable. And then, the influence of the relative inertia of the central body and the appendage on the frequency of the system is analyzed.
