Description

Air spring vibration damper and application thereof
Technical Field
The invention relates to the technical field of vibration reduction, in particular to an air spring vibration reduction device and application thereof.
Background
Large marine floating structures, such as oil production platforms and offshore wind power, are often located in remote offshore, deep-water, unshielded sea environments. The wave load and the wind load act on the structure body, which easily causes large-scale movement of the structure, has great influence on the strength and the fatigue performance of the foundation and the mooring system, and also brings serious challenges to the safety and the service life of the structure. To avoid the attendant safety and economic problems, the overall motion response amplitude of the floating structure must be reduced.
The existing vibration control scheme mainly reduces the overall motion of the structure by increasing the structural strength and the structural size, however, the deep sea floating platform is very high in manufacturing cost, and the method can additionally increase billions of capital investment, so that the cost is high and the efficiency is low.
Mounting a vibration damping device on the main structure is also a way to control the vibration of the structure. The air spring structure is a good vibration damping device, is in a traditional form in more applications at present, is mostly in a closed gas form, and cannot be used for an ocean structure.
In addition, the air spring device not only needs to effectively suppress the vertical vibration of the ocean platform, but also needs to have good effect of suppressing the rolling and pitching of the platform.

It should be noted that the damping portion is provided with an air hole to facilitate the air to flow in the oscillation cavity under the compression or expansion action.
When the air spring device applied to motion suppression of the ocean floating platform is used, liquid (including sea water) enters from the opening end of the vibration reduction part. In the process of seawater movement, the aim of inhibiting the floating body movement response is achieved through the interaction of liquid column oscillation movement and gas.

The vibration damping device provided by the invention inhibits the structure motion caused by waves and wind load by the interaction of gas, a liquid column and a damping plate.
For example, in an alternative embodiment, when the liquid moves to compress the gas, the gas between the damping portion and the opening compresses the gas toward the sealing end of the vibration damping portion, and at this time, the gas is influenced by the gas pressure difference between the two sides of the damping portion.
