| 摘 要： | 针对一种空间铰接柔性板结构的振动特性进行了分析,采用有限元分析方法给出通过柔性铰链连接的柔性板结构建模思路.利用有限元软件ANSYS对几种不同的铰链扭转刚度条件下铰接柔性板结构进行了模态分析,获得了模型结构的前五阶模态曲面及其模态频率.并比较了不同铰链刚度对铰接柔性板结构的模态振型和模态频率的影响.该分析有助于研究铰接柔性板结构的动力学和控制方案的设计、建模和分析.

| Abstract: | Vibration characteristic analysis of a kind of space flexible plates connected by flexible hinges are carried out,and the modeling idea of the hinge joint flexible plate is provided by employing finite element analysis method.Modal analysis is performed by using finite element software ANSYS under conditions of several different hinge's torsional stiffnesses.The first five modal shapes and natural frequencies are obtained,respectively.The effect of different hinge stiffnesses on modal shapes and frequencies... |
