对表面粘贴压电元件的复合材料薄壳结构的应变驱动原理、振动控制方程进行了分析。建立了自适应控制系统，对粘贴了压电材料的玻纤／环氧圆柱壳的振动进行了主动控制实验。结果表明，压电自适应壳结构能对薄壳的振动进行有效抑制，同时使壳体噪声辐射得到显著衰减。
The strain-driven principle and the vibration control equation of the composite thin-shell structure with piezoelectric elements attached on the surface were analyzed. An adaptive control system was established to control the vibration of the glass fiber / epoxy cylindrical shell with the piezoelectric material attached. The results show that the piezoelectric self-adaptive shell structure can effectively suppress the vibration of the shell, while significantly attenuating the shell noise radiation.
