Abstract

The utility model discloses a deep V wave crossing catamaran type. The seakeeping of a large wave crossing catamaran can be effectively improved through the deep V wave crossing catamaran type. A V-shaped section is used on a sheet body linear type of the deep V wave crossing catamaran type from the head portion to the tail portion. From the head portion to the middle-back portion of a catamaran body, the oblique-rising angle of the bilge part of the catamaran body with the length of at least 3/4 of a waterline is at least 20 degrees. By gradually lifting the height of a catamaran body tail keel line, the oblique-rising angle beta of the bilge part of the tail portion of the catamaran body is subjected to smooth transition by 5-7 degrees. According to the deep V wave crossing catamaran type, by ship model experimental verification, seakeeping is better than that of a circular bilge type, under the sea situation of the same level, compared with the circular bilge type, the pitching and vertical acceleration of a deep V section large wave crossing catamaran type line is obviously reduced.

Description

A kind of dark V wears wave twin-hull vessel ship type

Technical field

The present invention relates to wear wave twin-hull vessel seakeeping characteristics technical field, be specifically related to a kind of dark V and wear wave twin-hull vessel ship type.

Background technology

Wear the wave twin-hull vessel speed of a ship or plane high, generally more than 35 joints.In order to ensure the rapidity of boats and ships, a lot of large-scale lamellar body line styles of wearing wave twin-hull vessel generally adopt round-bilge ship type, as shown in Figure 1.But round-bilge ship type rough water quality is poor, under high sea situation, the resistance increment of boats and ships is larger with motion, causes the active of boats and ships and passive stall large, and occupant's seasick rate is higher.At present, generally adopt navigation automatic control technology large-scale wearing on wave twin-hull vessel abroad, in the case of not affecting the calm water speed of boats and ships, reach the object that improves rough water quality.But due to the technical sophistication of navigation robot control system(RCS), the initial laid down cost of boats and ships is high, and this technology is difficult to be promoted and apply as know-how.

Summary of the invention

In view of this, the invention provides a kind of dark V and wear wave twin-hull vessel ship type, can effectively improve the large-scale seakeeping performance of wearing wave twin-hull vessel.

Dark V of the present utility model wears wave twin-hull vessel ship type, lamellar body line style all adopts V-shaped section from stem to afterbody, wherein, hull stem is to postmedian, the turn of the bilge ramping angle of the hull of at least 3/4 length on water line is more than 20 degree, and by raising gradually hull caudal keel line height, make the turn of the bilge ramping angle β smooth transition to 5 ° of hull afterbody～7 °.

Wherein, the turn of the bilge ramping angle β of midbody is 25 °～30 °.

Beneficial effect:

Wear wave twin-hull vessel lamellar body section and adopt V-type section, can reduce vertical acceleration, reduce seasick rate, reduce pitching and rolling motion, wear wave twin-hull vessel rough water quality thereby improve.

Fig. 2 is that the dark V of the utility model wears the basic body plan of wave twin-hull vessel ship type.

Detailed description of the invention

Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.

The invention provides a kind of dark V and wear wave twin-hull vessel ship type, the section of dark monomer V line style is applied in to large-scale wearing in wave twin-hull vessel type, provide a kind of and be applicable to the large-scale new moldeed depth V that wears wave twin-hull vessel and wear wave twin-hull vessel type, thereby improve the large-scale seakeeping performance of wearing wave twin-hull vessel.Research shows, dark V ship type compared with slack bulge, its longitudinal movement performance and hang down and swing performance and be all better than round-bilge ship type, the vertical acceleration of bow and afterbody is also corresponding less, along with the raising of the speed of a ship or plane and sea situation, its motion advantage is more obvious.The dark V ship of monomer type has the advantages that rough water quality is good, and still water resistance and round-bilge ship type quite even decrease in the time of the high speed of a ship or plane, the feature of dark monomer V ship type, for wearing at a high speed the lamellar body design of wave twin-hull vessel, can be reached to the fast object of wearing wave twin-hull vessel rough water quality of raising.The dark V line style of monomer is generally that line style bench section is V-shaped section, deadrise angle is the knuckle line style of 20 °～25 °, than conventional hard chine or large many of round-bilge boat, be conducive to reduce the suffered alluvion in hull bottom, increase the resistance of hull longitudinal swaying in wave, so effectively improve the rough water quality of boats and ships.

The utility model is mainly that the V-type section of dark V line style is applied to and wears wave twin-hull vessel lamellar body, lamellar body line style all adopts V-shaped section from head to afterbody, stem is to all more than 20 degree (at least account for whole length on water line 3/4) of its V degree of line style midship rear portion, consider the needs of rapidity, improve last 1/4 captain's deadrise angle β smooth transition to 5 °～7 ° at afterbody.For this reason, the utility model is worn the dark V line style of wave twin-hull vessel exploitation to wear the concrete technical scheme of wave twin-hull vessel as follows mainly for the large-scale wave of wearing: the one, inherits the rough water quality advantage of dark V line style, its section employing V-type; The 2nd, the deadrise angle β at middle part gets 25 °～30 °, keeps suitable with dark V line style deadrise angle; The 3rd, reach from middle part to the successively decreasing of afterbody deadrise angle by raising gradually keel line height, optimize resistance, to take into account the balance of rough water quality and rapidity.As shown in Figure 1, as seen from Figure 1, it is obvious V-shaped section that the dark V of the utility model wears wave twin-hull vessel ship molded line matrix body bottom line style to hull form of the present invention, and knuckle is following is straight line substantially.Although slack bulge line style local (stern transom plate) has broken line.But broken line adopts arc transition, and whole bottom is all rendered as U-shaped from head to buttock line type.

Detailed description of the invention is: dark V of the present utility model wears wave twin-hull vessel ship type, lamellar body line style all adopts V-shaped section from stem to afterbody, wherein, hull stem is to postmedian, the turn of the bilge ramping angle of the hull of at least 3/4 length on water line is more than 20 degree, and by raising gradually hull caudal keel line height, make the turn of the bilge ramping angle β smooth transition to 5 ° of hull afterbody～7 °.Wherein, the turn of the bilge ramping angle β of midbody is 25 °～30 °, is conducive to reduce the suffered alluvion in hull bottom, increases the resistance of hull longitudinal swaying in wave, improves the rough water quality of hull.

Dark V of the present utility model wears wave twin-hull vessel line style and has the rough water quality better than slack bulge type through model experiment checking: under ad eundem sea situation, what adopt dark V section large-scalely wears the pitching compared with slack bulge type of wave twin-hull vessel molded line, vertical acceleration and have obviously and reduce.

In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
