摘要
对于均质挠性梁附着于中心刚体上 ,且挠性梁具有尖端质量和尖端转动惯量的结构 ,该文分析了其运动方程的约束模态和非约束模态解 ,分别得到了相应的振型函数和普遍的频率方程 ;在此基础上定量分析了约束模态和非约束模态的频率随不同挠性梁 /中心刚体惯量比的不同近似程度 。
Considering a kind of flexible structure, which has uniform flexible beam,attached to the center rigid body and there are point mass and point moment of inertia.The solution of constrained and unconstrained mode for the equations of motion is analyzed and the general equations of frequency are obtained.Based on these analyses, quantitative comparison between constrained and unconstrained mode frequency with different flexible/rigid body inertia is made.The theoretical basis for modeling and design of controller of such flexible system is provided.
