Thin-walled cylindrical shells are widely used in industries, such as the main parts of aircrafts, rockets, and submarines. Except for meeting the load-bearing capacities, such structures must also have good vibration and acoustic performances. However, it is still a challenge to control the multi-modal vibration of cylindrical shells at low frequencies. This study explores the cutting-edge local resonant piezoelectric metamaterials to control the low-frequency vibration of cylindrical shells. A novel cylindrical meta-shell with piezoelectric materials and digital circuits was proposed, and a multi-resonance transfer function is implemented in each digital circuit. A method to optimizing the parameters in the transfer function for the purpose of vibration reduction is developed. The vibrational characteristics of the meta-shell are numerically analyzed using the finite element method. Numerical results clearly demonstrate that by delicately designing the parameters in the transfer function, the meta-shell can reduce the peak amplitudes of the first five modes by 30 dB or more. Therefore, the proposed piezoelectric cylindrical meta-shell may open new opportunities in vibration mitigation of transport vehicles and underwater equipment.

In order to suppress the low-frequency flow-induced vibration of fluid conveying pipeline, this paper develops a magnetorheological damping (MRD) pipe clamp due to its simple structure and strong dynamic adjustability. The mechanical dynamic model of MRD pipe clamp is established, and the vibration control algorithm based on PID is simulated. Comparison analysis on the vibration damping performance of the MRD pipe clamp under uncontrol, passive control, and PID control are conducted. The damping performances of MRD pipe clamp are tested under uncontrol, passive control, and PID control algorithm. The experiment results exhibited that the attenuation rate of each axial displacement and acceleration of pipe system using PID algorithm were more than 80% under sinusoidal excitation force of 600 N and excitation frequency of 2.5 Hz. The experiment results have verified the correctness of the simulation analysis in terms of value and trend. This research will provide the guide for the design and engineering application of MRD pipe clamp system.

Magnetorheological (MR) dampers, as an intelligent vibration damping device, can quickly change the damping size of the material in milliseconds. The traditional semiactive control strategy cannot give full play to the ability of the MR dampers to consume energy and reduce vibration under different currents, and it is difficult to control the MR dampers accurately. In this paper, a semiactive control strategy based on reinforcement learning (RL) is proposed, which is based on “exploring” to learn the optimal value of the MR dampers at each step of the operation, the applied current value. During damping control, the learned optimal action value for each step is input into the MR dampers so that they provide the optimal damping force to the structure. Applying this strategy to a two-layer frame structure was found to provide more accurate control of the MR dampers, significantly improving the damping effect of the MR dampers.
