This paper studies on an engineering adapter model of satellite emission. 4-node Mindlin plate element is used for the finite element method (FEM) modeling. The electromechanical influence of distribute piezoelectric actuator is regarded as the boundary conditions. The results of mode calculate with FEM is accurate enough for engineering application by compared with experiment results. Independent modal space control(IMSC)method and negative velocity feedback control are used in investigation of active vibration control. Results of simulations suggested that the control method is efficiency by using a few piezoelectric actuators.%针对某卫星发射过程中所应用的适配器模型,利用4节点Mindlin板单元对其进行了有限元建模,将分布式压电作动器的影响作为动力学边界条件加入模型当中;试验数据与理论计算结果对比证明该方法能够满足精度要求,此外与通常的层合理论建模方法相比,该方法更加简洁,大大降低了计算量;利用基于独立模态空间控制的方法对锥壳结构进行了振动主动控制研究,仿真结果可以看出利用少数作动器即可达到理想的控制效果.由于控制器本身比较简单,具有很好的鲁棒性,因此对于实际工程应用具有非常重要的指导意义.
