摘要
利用压电介质的二维本构关系 ,推导出带有上、下压电激励器的弹性梁在电场作用下的位移、应力分布的解析表达式 ,得到了压电激励器对弹性梁的等效作用力 ,最后给出了带有上。
Based on the two_dimensional constitutive relationships of the piezoelectric material, an analytical solution for an intelligent beam excited by a pair of piezoelectric actuators is derived. With the solution the force and moment generated by two piezoelectric actuators and a pair of piezoelectric actuator/sensor are obtained. Examples of a cantilever piezoelectric laminated beam or a simply supported piezoelectric laminated beam, applied with voltages, are given.
