Cutouts are inevitable in structures due to practical consideration. In order to investigate the free vibration of functionally graded plates with multiple circular and non-circular cutouts, finite el...
多维隔振装置自由振动方程及其解（Free Vibration Equation of a Multidimensional Vibration Isolation Device and Its Root）
隔振 动力学方程 机构
2009/8/11
通过多方位多层次结构组合实现多维隔振时，其结构复杂、难度大，因此提出以反向对称布置双直角Stewart机构及上、下平台组成多维隔振装置，利用一层结构实现多维隔振，建立了自由振动方程并进行求解。由解看出，该装置固有频率在5?Hz以下，振动衰减较快。使用该装置，仿真可实现沿坐标轴的3个移动和绕坐标轴的3个转动，加速度传递系数均小于1。依据所推导的公式，确定该装置的刚度系数、阻尼系数和结构尺寸，可将该装...
