  • The experimental results of dynamic response for the shell with different damping-ring/sleeves verified the validity of the proposed simplified model and the numerical simulation results in this paper.The influences of variable parameters on the dynamic response,such as the width,thickness,gap size and installed position of damping-ring/sleeves were also discussed.The region of installation of damping-ring has great influence on its effect of vibration control.With the effect of "frequency-transfering" and friction damping,the damping-sleeves reduce the peak of the vibration notably.When the shell vibrates in different circumferential waves,even for the same damping-ring/sleeve,its effect of vibration control is different.
