摘要

本文的目的是给出在静、动态轴向压缩力作用下压层薄钢板支撑失稳控制的精确解。采用Tiersten导出的机电压电本构律。根据考虑几何非线性的缺陷法的基本原理，推导了驱动和控制的求解方法。给出了压电层合支撑结构静、动态控制的封闭解。采用PVDF智能材料层压在薄钢板上，演示了驱动和主动控制。

Smart Steel Plate Structures

The objective of this paper is to present the exact solutions for instability control of piezolaminated thin steel sheet struts subjected to static and dynamic axial compressive forces. The electromechanical piezoelectric constitutive law derived by Tiersten is adopted. Solution for the actuation and control is derived from the basic principle of the imperfection approach considering geometric nonlinearity. Closed form solutions for static and dynamic control of piezolaminated struts are prescribed. The actuation and active control is demonstrated using PVDF smart materials laminated on thin steel sheet.
