| 摘 要： | 为研究舰船结构振动主动控制有效方法,采用线性二次型独立模态空间控制法设计控制器,对舰船振动信号激励下压电智能梁的振动进行主动控制。基于Hamilton原理建立压电智能结构的有限元模型,并利用精细积分法计算前3阶模态的位移响应。编制了相应的计算机程序,对舰船振动信号激励下梁结构的振动进行主动控制数值仿真。由仿真结果可见,控制可以有效地实现,为舰船结构振动主动控制提供理论基础。

| Abstract: | To research the effective method for active vibration control of vessel structure,an Independent Modal Space Control(IMSC) technique based on Linear Quadratic Regulator(LQR) method was adopted to design the controller,taking an active vibration control of a piezoelectric smart beam,which is under the vessel's vibration signal excitation.The finite element model of the piezoelectric composite structure was developed based on the Hamilton's principle.Furthermore the high precise direct integration method was ... |
