【 摘 要 】

In this paper, the dynamic and vibration control effect of macro-fiber composite (MFC) were studied on the plate and shell structure, proposing a new calculation method of MFC coupled-plate structure actuating equation. Based on the first kind of piezoelectric equation, this paper deduces the equation of P1-type MFC composite plate structure, considering the influence of the Poisson's ratio of the controlled structure and the effect of the MFC plane strain on MFC's actuating force and actuating moment. In this paper, the vibration control experiment of the MFC coupled-plate structure is completed. The deviation between the experimental results and the simulation results is less than 7.5%, indicating that the P1-type MFC actuating equation is correct and can be used in the simulation calculation of vibration control for the MFC coupled-plate structure.
