| 摘 要： | 以输入结构的总功率流和所需主动力幅值为控制目标函数,对输入圆柱壳结构振动功率流的主动控制进行了研究,并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.利用导纳函数求解结构响应,构造目标函数为二次型函数形式,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.

| Abstract: | Studing the vibration control of cylindrical shell structure is important for engineering.In this pa-per,the active control of cylindrical shells based on structure power flow and control inputs is analysed.The total input power flow and the amplitude of control force are selected to be the objective function and several important parameters which influence the control effect are discussed.The vibration response of the cylindrical shell stimulated by the primary and secondary forces is studied by using mobi... |
