摘要
为解决在作用电压和机械力的耦合载荷作用下具有压电元件圆薄板传感器的非线性弯曲问题,基于VonKarman薄板非线性理论和压电本构方程,导出具有压电元件圆薄板传感器非线性弯曲控制方程.利用修正迭代法得到在机、电载荷共同作用下轴对称圆薄板的载荷、挠度和电压的关系式.通过算例分别讨论机械载荷和作用电压的变化对圆薄板弯曲变形的影响,结果表明:通过改变压电元件作用电压的大小和方向,可以有效地控制圆板的曲变形.该成果对具有压电元件圆薄板传感器弯曲变形控制具有一定的理论指导意义.
In order to investigate the problem associated with nolinear bending of pressure sensor of circular thin plate with piezoelectric patches under the action of coupling load of mechanical pressure and applied voltage,based on Von Karman plate theory and basic piezoelectricity equation,the nonlinear bending governing equation is derived and solved using modified iterative method in this study.The nonlinear relation of load,deflection and applied voltage is obtained.Numerical example shows that the bending deflection of the circular plate can be effectively controlled by regulating the magnitude and direction of voltage applied.The study results provide some useful value.
