“…Currently, vibration control primarily focuses on two aspects: passive suppression and active control [10,11], including damping vibration [12,13], vibration isolation [14], and dynamic absorbers [15], among others. Lazar et al [16] proposed a tuned inertial damper as an alternative to traditional dampers, which effectively suppresses cable vibration.…”

Carbon fiber pipe of the laser guiding arms are highly sensitive to vibration, and external vibrational excitation can significantly degrade the accuracy of the optical path. Firstly, this paper proposes a carbon fiber optical arm pipe magnetic support system for low-frequency and impulse vibrations. The overall stiffness of the magnetic support is reduced by the cooperation of mechanical springs with positive stiffness and magnetic springs with negative stiffness. Secondly, based on analytical calculations of magnetic forces and finite element simulations, a comprehensive dynamic model of the system is established and solved. Finally, an experimental platform for the equipment is set up, and both frequency sweep response tests and impulse vibration response tests are conducted on the system. The results demonstrate that the proposed magnetic support with low stiffness effectively reduces the interference of low-frequency vibrations on the supported carbon fiber pipe, and the vibration amplitude of the carbon fiber pipe has significantly decreased by 67%.

“…Several passive control systems have been used in past studies to attenuate vibrations of structures and machines. Particle dampers belong in these systems, and their attractiveness [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] is based on their simplicity, low cost, and effectiveness in reducing the dynamic response of mechanical systems and machines. Lately, their use has been extended in the civil engineering area [17].…”

An experimental study was performed examining the effectiveness of a multi-compartment damper in attenuating the response of structures under random and earthquake excitations. The damper consisted of four compartments of unequal size; it was mounted on a small one-story steel structure. The same number of steel spherical particles were placed inside each compartment, resulting in filling area ratios (the total area of the squares around the projected particles divided by the area of the compartment) from 40% to 70%. The damper was effective in reducing the response displacement and acceleration of the structure considerably. The use of different filling area ratios enabled the damper to be effective for a wide range of excitation levels.
