The active vibration control of structures using the piezoelectric material has been extensively investigated. Previous researches handled the thermal effect as important role for the uniform temperature distribution. Thermal stress effects on the composite sandwich plate structure have been reported in Ref.[1]. Further, Xiang and Yang [2] investigated the free and forced vibration of three-layered beam considering the thermal gradient with steady heat conduction. K Lam et al.[3] developed a model based on the classical laminated plate theory for the active vibration control with distributed piezoelectric sensors and actuators. Choi et al.[4] studied the active vibration control of the pre-twisted rotating composite thin-walled beam integrated MFC actuators and PVDF sensors.
In this work, active vibration control of smart skin structure integrated piezoelectric PVDF sensor and MFC actuators under heat transfer is to studied. The model is based on the First-order Shear Deformation Theory of Plate and von Karman strain-displacement relationships. The thermal condition is obtained by steady state heat diffusion equation using finite difference method. The active damping effect of piezoelectric layers for the vibration suppression of structures under the thermal loading is considered in detail.
