智能材料结构是飞机中的一项重要技术，而减振降噪自适应智能结构是其中的一个重要分支。本文针对飞机、直升机和空间结构的一些典型结构的减振降噪方法进行了研究。对以上结构分别制作了实验模型，在其上布置压电传感器和驱动器，借助测控系统平台，通过一定的自适应控制算法对振动进行隔离和抑制，取得良好效果。 Intelligent material structure is an important technology in the aircraft, and adaptive intelligent structure of vibration and noise reduction is one of the important branches. In this paper, some typical structures of aircraft, helicopters and space structures are studied. Experiments were made on the above structures respectively. Piezoelectric sensors and actuators were arranged on them. With the help of the platform of the measurement and control system, some adaptive control algorithms were adopted to isolate and suppress the vibration and achieved good results.
