An Experimental Investigation on Active Vibration Control of Y-7 Aircraft Fuselage Using Piezoelectric Sensors and Actuators

由于实验规模与复杂性的限制 ,将压电材料用于实际飞机振动主动控制的实验研究极少 ,因而缺少对其实用潜力的探讨。为评估压电陶瓷在实际飞机结构上用于减振的可行性和效果 ,以运七飞机座舱壁板为试件 ,实地进行了基于准独立模态控制策略的主动振动控制实验 ,取得理想的控制效果 ;表明了建模和控制方法的正确性与有效性 。

There are few active vibration control experimental investigation on actual aircraft structure using piezoelectric sensors and actuators owing to large scale and complexity of the experiment. Therefore there is a lack of discussion about practicability of piezoelectric structure. In order to evaluate feasibility and effect of suppressing vibration of actual aircraft structure using piezoelectric sensors and actuators, a test for damping control on the panel of an Y7 aircraft fuselage was carried out in the field on site, based on independence modal control approach. The results show that the model and the control strategy of this paper are effective and practicable, and indicated that it is feasible and potential to use piezoceramics to realize the active vibration control for aircraft structures.
