Vibration Power Flow Analysis of the Cylindrical Shell Structure based on the Active Control

    摘要
  • 摘要: 研究基于主动力方式的圆柱壳结构输入振动功率流控制，分析了圆柱壳受激振动的响应，利用导纳函数求解结构响应。将构造结构总的输入功率流为二次型函数作为控制目标函数，利用哈密尔顿二次型最小值理论给出最优控制力前馈控制表达式。分析了几个重要参数对壳体结构振动功率流控制效果的影响。

     

    Abstract: The active control method of input power flow of the hollow cylindrical shells is investigated in this paper. By using mobility function,the vibration response of the cylindrical shell stimulated by the primary and secondary forces is studied. The total input power flow is expressed in an equation of Hermitian quadratic form as the objective function. The optimum set of secondary force is obtained and several important parameters which influence the control effect are analyzed.
