Linked damping system and method for ship equipment

Abstract

The invention relates to a linked damping system for ship equipment. The linked damping system comprises a plurality of vibration sensors, a plurality of magnetic fluid damping devices and a main controller, wherein each vibration sensor is mounted on each vibrating source of a ship for detecting a vibrating signal of the corresponding vibrating source; multiple magnetic fluid damping devices aremounted on each vibrating source, and the corresponding magnetic fluid damping devices which need to start are controlled according to vibration; and a detecting signal input end of the main controller is separately connected to each vibration sensor, and a control signal output end of the main controller is separately connected to each magnetic fluid damping device, so that the corresponding magnetic fluid damping device is controlled to work according to detected vibration intensity and a vibration control condition. The system and the method can effectively reduce vibrations generated by ship equipment.

Description

technical field [0001] The invention relates to the technical field of ship vibration reduction, in particular to a ship equipment linkage vibration reduction system and method. Background technique [0002] When the ship is sailing, the vibration and noise generated by the equipment are very large, which will affect the normal rest of people, and even affect the health of the human body. Different frequencies have different effects on the parts of the human body. Each part of the human body has its own characteristics. Natural frequency, when the vibration frequency generated by the vibration of the hull is equal to the frequency generated by some parts of the human body, resonance will occur, which will cause harm to the human body. Generally, some low-frequency vibrations are difficult for the human body to feel, so we will always have uncomfortable reactions unconsciously.

AI Technical Summary

Problems solved by technology

In the prior art, most of the marine equipment adopts mechanical, that is, passive methods for vibration reduction. As described in patents such as CN201410435191.4 and CN201721824375.5, mechanical devices are used to design dampers to reduce the vibration of marine equipment. The traditional vibration and noise reduction method has certain defects, that is, it can only reduce the vibration of the equipment fixedly, but cannot target a specific vibration

For example, when the vibration frequency of the equipment is at low frequency or ultra-high frequency, the device cannot play a good role in vibration reduction.

At present, there are also some active damping devices, such as CN 108768346 A, etc., which adopt active damping methods, but they are mainly used in the damping of vehicles, and are not suitable for damping of ships.
