含压电片层合板的静变形控制

借助阶梯函数，建立了含有任意分布的用作执行器的的压电片的层合板弯曲方程，然后利用该方程，进行了层合板静变形控制的研究，最后给实例，用“遗传＋配点”法对压电片的位置和尺寸进行了优化。结果表明，用压电片作执行器，用“遗传＋配点”法进行优化是对板进行静力变形控制的一条有效途径。

SHAPE CONTROL OF LAMINATE PLATE CONTAINING PIEZOELECTRIC PATCHES

By applying Heaviside function, the equations of governing the laminate plate which possesses spatially distributed piezoelectric patches are established. Based on these equations, some problems about the shape control are discussed. By using the collocation point method combined with genetic algorithm, the optimal locations and scales of these piezoelectric patches are selected. Numerical examples are presented to illustrate the efficacy of the algorithm.
