摘要
简要介绍了新兴的智能复合材料结构及其应用发展前景。对双压电元件复合材料层合板的振动衰减主动控制给出了有限元计算公式,导出了压电激振器、传感器的输入、输出方程,建立了结构振动主动控制的数学模型。
Smart composite structure technology will undoubtedlly yield a wide range of new material plus and material sensing/actuation for advanced technology in aviation, space flight, satelite, etc. . It is of great application background and developing value. In the paper the dynamic Finite Element Method for composite laminated plate with PZT Sensors/Actuators, which may be used as active control of vibration attenuation for flexible structures is presented, and the Input/Output equations of PZT S/A are derived. This may provide the theorical bases for advanced study of different active control algorithms.
