Embodiment Construction

[0040] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0041] Such as Figure 1-Figure 3 As shown, a miniaturized six-degree-of-freedom sea wave compensation multi-purpose boat, below is a sailing hull 1 navigating in water, which includes steering equipment 1-1, propulsion equipment 1-2, anti-rollover wing 1- 3 and equipment compartments 1-4, and the upper planes 1-5 of the sailing hull have local structural reinforcement and planarization treatment at the installation position of the servo electric cylinder to ensure that the platform has sufficient strength under wave compensation and is parallel to the sea level; sailing The inclination design of the plane 1-5 on the hull is high at the front and low at the rear, which facilitates the collection and treatment of seawater that may enter the boat; the anti-rollove...

Abstract

The invention discloses a six-degree-of-freedom offshore wave compensation multipurpose boat and a wave compensation method thereof, the wave compensation multipurpose boat comprises a navigation boat body, a deck and a six-degree-of-freedom electric wave compensation system, and the deck is a whole needing wave compensation; the six-degree-of-freedom electric wave compensation system is a connecting part of a navigation boat body and a deck and is composed of an electric cylinder and other components or auxiliary accessories necessary for electric wave compensation. By measuring motion attitude values of rolling, pitching, heaving, swaying, surging and yawing of a ship body, compensation values of rolling, pitching, heaving, swaying, surging and yawing are calculated according to an inverse solution algorithm of wave compensation values, all servo electric cylinders are controlled to act, and six-degree-of-freedom compensation of an upper deck is achieved. Wave compensation can be carried out on the whole deck, the influence of waves on a boat body is reduced, six-degree-of-freedom grouping is controlled through the layered wave compensation platform structure, and more working space is provided for the wave compensation structure.

Description

technical field [0001] The invention relates to the field of ship design and manufacture, in particular to a six-degree-of-freedom sea wave compensation multipurpose boat and a wave compensation method thereof. Background technique [0002] Small and medium-sized ships are widely used for marine leisure and entertainment yachts, and small and medium-sized ships are more affected by waves than medium, large and even large ships, which can easily cause dizziness and inconvenience to passengers. With the development of wave compensation technology, the marine parallel stable platform has become the main solution to deal with the impact of waves on shipboard personnel and equipment. The hydraulic parallel platform has the advantages of high rigidity, stable structure, strong bearing capacity, high precision and small motion inertia. At present, it is mainly aimed at the application of on-board equipment on medium and large ships, such as wave compensation trestles, wave compensa...
