摘要
针对在某些特殊情况下飞机座舱振动、噪声过大的实际情况 ,本文对其进行了振动、噪声抑制研究。以某飞机座舱模型为研究对象 ,利用压电智能结构 ,并结合振动主动控制方法和 L MS自适应滤波算法 ,实现了一套完整的飞机座舱模型振动、噪声主动控制系统。最后本文给出实验结果 ,证明了此方法对飞机座舱模型振动。
Some researches have been done on the active vibration and noise control of a fighter cockpit model,because it may generate larger vibration and noise under certain circumstances harmful to pilots and precise instruments.We used piezoelectric smart structures;active vibration control technology and LMS adaptive filter algorithm to control the vibration and noise of the cockpit model and had realized a control system.The experiments on the control of the cockpit model vibration and noise were performed.The experimental results show that the control system is effective.
