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

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.
