Considering the direct and converse piezoelectric effect, expressions of piezoelectric membrane internal forces in the piezoelectric constrained layer were given. The control equations of the piezoelectric constrained layer and host plate were obtained in according with the thin plate theory. Based on the layer wised principle, the integrated first order differential equation of an active constrained layer damping (ACLD) plate was derived for the simply supported boundary condition. Then, this method was expanded to the ACLD plate with cantilever boundary condition by virtue of geometric analogy method. Employing the extended homogeneous capacity precision integration approach, a high precision semi-analytical method was proposed to analyze the dynamic characteristics of the ACLD plate with various boundary conditions. The comparison with the literature results has verified the accuracy and effectiveness of the present method.

分析了磁流变阻尼器的力学特性,将其应用于多维减振系统中。采用经典的三平移并联机构作为多维减振平台的主体机构,推导出其位置逆解公式;建立了系统动力学状态方程模型,以运动学方程得到的支路加速度作为输入信号,控制器采用了基于线性二次型最优控制理论的半主动控制算法。考虑到动态过程中机构动力学方程的复杂性,采用稳态方法对并联机构处于某一运动姿态的支路移动副振动进行控制,从而控制了整个平台的振动。仿真结果表明,所采取的控制算法有较好的控制效果。

A neural-network (NN)-based active control system was proposed to reduce the low frequency noise radiation of the simply supported flexible plate. Feedback control system was built, in which neural network controller (NNC) and neural network identifier (NNI) were applied. Multi-frequency control in frequency domain was achieved by simulation through the NN-based control systems. A pre-testing experiment of the control system on a real simply supported plate was conducted. The NN-based control algorithm was shown to perform effectively. These works lay a solid foundation for the active vibration control of mechanical structures.
