压电材料与智能结构在振动控制中的研究与前景展望

Application and Development Trend of Vibration Control Based on Piezoelectric Materials and Intelligent Structures

智能结构具有自诊断、自适应特性,越来越多地应用于航天结构、机器人、高精度光学系统等方面。压电材料具有正、逆压电效应,既可以作为作动器又可做传感器,因而常被应用于智能结构。基于压电材料的特点介绍了振动控制方法,对目前智能结构在振动控制领域的应用现状进行了回顾,最后指出了今后需要解决的主要问题。

Intelligent structure has the characters of self-diagnosis, self-adaptation. So it is widely used in the fields of large-scale aerospace structure, robot, the high-accuracy optical system and other areas. Sensor and actuator based on the intrinsic direct and converse piezoelectric effects of piezoelectric materials have been widely used in intelligent structures. The methods of vibration control based on the characters of piezoelectric materials were introduced. Application of piezoelectric materials in vibration control now have been reviewed and the main problems still need to solve were raised.
