智能复合材料结构振动控制力学模型

THE MECHANICAL MODEL OF SMART COMPOSITE STRUCTURE FOR ACTIVE CONTROL OF VIBRATION

介绍了在航空、航天等高技术领域中柔性结构振动衰减控制90年代初期新兴的智能复合材料结构技术及应用发展前景．对一个具有应用背景的双压电片复合材料层合板帆板结构的振动衰减控制系统给出了数学模型，导出了压电传感器／激振器的输出／输入方程．进行了最优控制算法数值仿真，结果表明，其控制效果是显著的．

Smart composite structure technologies will undoubtedly yield the wide effets on materials engineering and sening and actuation technology of aviation, spacefligh, satelite. It pesses a wide application background and developping values. Ths paper gave the dynadric calculational forinations of composite laminated plate with PZT sensors-actuators, which may be used as the active control of vibration attenuation of flexble structure, and derived out the input/output equations of PZT S/A. This may provide the theoretical hase for the conequenced study of the different active control algorithm.
