【摘要】 利用热压电介质的动态控制方程讨论各耦合场对智能结构控制和传感性能的影响。提出用有限元分析法对热压电基体结构的热应力和热变形进行计算 ,以确定智能结构中致动器 /传感器的最优配置。
【Abstract】 The dynamic governing equations for piezothermoelasticity continua are presented to discuss the effects of coupling fields on the control/sensing performance in an intelligent structure. According to those analyses, a finite element analysis method is developed to calculate the thermal stress and thermal deformation of piezothermoelectric basal structure in order to determine the piezoelectric actuator/sensor optimal placement in the intelligent structure.
