AbstractThe matched mass damper (TMD) is used to ensure the safety and stability of the offshore platform; however, the line damper operates at a single reso- nance frequency and only provides vibration suppression in a narrow frequency band. Therefore, this paper proposes a magnetic TMD with two pairs of per- manent magnets on both sides of the structure, generating nonlinear repulsive force. This makes the vibration of the magnetic TMD damping structure reli- able and stable in a wide frequency range under the influence of earthquakes. Matched mass dampers (TMD) are widely used to control and reduce vibra- tion in engineering structures such as buildings, towers, bridges, and wind turbines. The traditional expression of TMD is the point mass connected to the structure through springs and dampers. However, many TMDs differ from this model because multiple mass components have different amplitudes and direc- tions of motion. The TMDs have acquired quality. Bulk add to the increased inertia and additional mass, the internal TMD movement is reduced. The effec- tive mass of the TMD must be calculated correctly to predict the efficiency of the TMD and adjust the TMD correctly. The review first briefly introduced the detection techniques and methods used in POF sensors, focusing on the different advantages and limitations of the different detection schemes used. Because POF is easy to handle, low cost and has high tensile strength, people are interested in its useSome workers showed how to monitor the structure’s condition, especially measuring deformation, curvature, load, displacement, vibration and crack detection.
