Vibration control device for offshore floating structure under wave current excitation

Abstract

The invention discloses a vibration control device for an offshore floating structure under wave current excitation. The vibration control device comprises a stand column, a floating frame installed at the upper end of the stand column, having the side face close to the lower end being of a conical curved surface structure, and provided with a driving device installed on the side face, a buffer device mounted on the side surface, close to the upper end, of the floating frame and used for driving the driving device, a submerging and floating device that is located below the driving device, installed on the outer side of the stand column, driven and adjusted by the driving device and connected with a seabed through a first steel cable, and a damping device installed at the bottom end of the stand column, driven by the submerging and floating device to move longitudinally and connected with the seabed through a second steel cable.

Description

technical field [0001] The invention relates to the technical field of offshore wind power equipment, in particular to a vibration damping device for an offshore floating structure excited by waves and currents. Background technique [0002] Offshore floating structures are the development trend of future offshore structures, such as applied to offshore platforms, wind turbines and other equipment. However, due to the continuous surge of ocean waves, equipment such as ocean platforms and wind turbines are excited by waves and currents and are prone to vibration. The vibration damping device of the existing offshore floating structure, in operation, when it is impacted by waves, the equipment will sway with the waves, and the center of gravity of the floating device and the equipment installed on it will deviate greatly, resulting in Vibration is relatively large, affecting the normal operation of the device. [0003] Therefore, those skilled in the art provide a vibration ...
