【摘要】 基于一阶剪切效应Mindlin板理论,建立了在热载下含分布式压电作动器的复合材料层合板有限元分析模型和控制方程,给出了考虑层合板与压电作动器间粘结层的有限元方法和相应的有限元列式。对悬臂层合板,研究了热载荷作用下压电作用器修复前后的板中面变形,并采用最小二乘法进行了电压优化。更多还原

【Abstract】 Based on the first order shear deformation plate theory,a numerical analysis model of composite laminated plates with distributed PZT actuators under thermal load was established,and the corresponding formulae of finite element method were present considering the effect of adhesive layer between PZT actuator and plate.Considering an one end clamped plate,the thermal deformation of the plates induced by different temperatures on the upper and lower surfaces and the thermal deformation compensation for the plates using PZT actuators were studied respectively,then the optimization of voltages applied to each actuator was discussed.更多还原
