Embodiment Construction

[0040] To elaborate on the technical content of the present invention, the object achieved and the effect, the following in conjunction with the embodiment and in conjunction with the accompanying drawings are described.

[0041] as Figure 1- Figure 3 As shown, a miniaturized six-degree-of-freedom offshore wave compensation multi-purpose boat, below which is the navigation hull 1 for navigation in the water, which contains steering equipment 1-1, propulsion equipment 1-2, anti-rollover wing 1-3 and equipment cabin 1-4, and the upper plane of the navigation hull 1-5 has local structural strengthening and planar treatment at the installation position of the servo-electric cylinder to ensure that the platform has sufficient strength and parallel to the sea level under the wave compensation; the sloped design of the front height and low of the front height and low of the upper plane of the navigation hull 1-5, It is convenient for the collection of seawater that may enter the boat; th...

Abstract

The invention discloses a six-degree-of-freedom sea wave compensation multi-purpose boat and a wave compensation method thereof. The wave-compensation multi-purpose boat includes a sailing hull, a deck and a six-degree-of-freedom electric wave compensation system, and the deck is a whole that needs wave compensation; The six-degree-of-freedom electric wave compensation system is the connecting part of the sailing hull and the deck, and consists of electric cylinders and other necessary components or auxiliary accessories for electric wave compensation. By measuring the motion attitude values ​​of roll, pitch, heave, sway, surge and yaw of the hull, the roll, pitch, heave, sway and surge are calculated according to the inverse solution algorithm of the wave compensation value and the compensation value of the yaw, control the action of each servo electric cylinder, and realize the six-degree-of-freedom compensation of the upper deck; The structure controls the grouping of six degrees of freedom, which provides more workspace for the heave compensation structure.

Description

Technical field [0001] The present invention relates to the field of ship design and manufacture, in particular to a six-degree-of-freedom offshore wave compensation multi-purpose boat and a wave compensation method thereof. Background [0002] The wide range of applications for offshore leisure and entertainment yachts is mostly small and medium-sized ships, and small and medium-sized ships are more obviously affected by the waves than medium-sized or even large ships, which is very easy to cause dizziness and inconvenience of the accompanying personnel. With the development of wave compensation technology, the marine parallel stabilization platform has become the main solution to deal with the impact of waves on shipboard personnel and equipment, hydraulic parallel platform has the advantages of large stiffness, structural stability, strong bearing capacity, high precision, small motion inertia, etc., and is currently mainly aimed at the application of medium and large and even...
