飞机某复合材料弯管的振动主动控制

Vibration Active Control of Composite Material Tube Used in Plane

针对某飞机上典型的复合材料弯管结构的振动 ,采用压电元件作为传感器和作动器 ,通过有限元分析其振动模态以确定压电元件的施加位置 ,进一步利用自适应前馈控制策略 ,对其振动进行了主动控制 。

The aim of this article is to suppress the vibration of composite material tube used in plane through active control. Piezoelectric actuators and sensors are used. In order to determine the position and numbers of sensors and actuators, the modes of tube are analyzed by finite element method. Self adaptive feed forward control strategy is adapted to suppress the vibration. The vibration of tube is controlled effectively.
