摘要: 提出一种主动振动控制平台的模块式设计概念,采用有限元建模方法对自行设计的模块式隔振单元台体进行结构动力学方程建模,并利用动力学方程对该隔振单元进行简单开环主动振动控制的模拟,得出适当调整主动元件作动器的输出力可以有效控制隔振平台两个自由度方向振动的结论.通过对隔振单元振幅放大因子的研究,发现在隔振单元工作频带范围内没有出现其固有振动,因而对于大部分低于其固有频率的振动将采取主、被动隔振技术来完成.综合上述隔振单元动力特性的进一步分析,可知所建动力学模型能够较好地描述隔振单元的动力特性.

Abstract: A modular design concept for an active vibration control platform was put forward, which adopted finite element method to establish the structure dynamic model of a modular vibration isolation module. And the dynamic equation was applied to simulate simple open active vibration control of this vibration isolation module, and then the conclusion that the vibration in two degree-of-freedom directions of this vibration isolation platform could be effectively controlled by appropriately adjusting the output force of driving part actuator was gained. Through the research on vibration amplitude factor, the natural oscillation of this module was not found within its working frequency band. Therefore, active vibration isolation technology was utilized for vibration whose frequency was lower than its natural frequency. Finally further analysis was carried out on dynamic characteristics of the above vibration isolation module, which demonstrated that the established dynamic model could well describe the dynamic characteristics of the vibration isolation module.
