|
摘要
采用安装在主减斜撑杆上的压电叠层作动器建立了直升机主动隔振系统。基于压电材料本构关系推导了压电叠层作动器的驱动方程,建立了压电叠层作动器驱动的主减主动隔振系统动力学模型。采用了自适应滤波控制方法,通过最小均方算法实现了自适应控制。直升机主动隔振仿真实验表明了该系统具有高效的隔振效果。
The active vibration isolation system of helicopter is established by using piezoelectric stack actuators installed on struts of main gearbox.Based on the constitutive relation of piezoelectric materials,the driving equation of the piezoelectric stack actuator is deduced,and the dynamic model of the main gearbox vibration isolation system driven by the piezoelectric stack actuators is established.The adaptive filtering process is realized by the least mean square(LMS)algorithm.The active vibration isolation simulation of helicopter is carried out,indicating that the system has an effective vibration isolation effect.
