Abstract

The utility model relates to a ship form of a large Ro-Ro passenger ship, in particular to the hull line of large Ro-Ro passenger ships, which comprises bow of the hull, stern of the hull, and the deck, characterized in that: the perpendicular is L=130-180 meters; the molded breadth is B=24-30 meters, and the speed is 16-30 knots; head of the underwater hull line is provided with a bulbous bow, and the stern is provided with a double-tail. A U-shaped cross section is provided with a perpendicular range of 0.17L after the forward perpendicular at the bow; above water hull line from the eighteenth stop the twentieth stop is largely flared cross section hull line. The utility model has the advantages of that: 1. Excellent resistance performance and propulsive performance, capable to sail precipitous sea; 2. Excellent seakeeping and maneuverability, with sufficient intact stability and damaged stability, further optimized based on hull line of existing Ro-Ro passenger ships; 3. A series of tests in towing tank verify the existence of above characteristics.

Description

A kind of large ro-ro passenger ship ship type

Technical field

The utility model relates to a kind of large ro-ro passenger ship ship type, relates in particular to the hull lines of large ro-ro passenger ship.

Technical background

Large ro-ro passenger ship has transportation full-sized car and passenger's dual-use function, with regard to its in-use performance, need all have stronger characteristic at aspects such as rapidity, rough water quality, road-holding property, intact stability and damaged stabilities.But existing large ro-ro passenger ship, its Combination property aspect is desirable not to the utmost toward contact, has the more weak problem of some aspect performance.

Summary of the invention

Technical problem to be solved in the utility model is that the large ro-ro passenger ship ship type that provides a kind of Combination property outstanding is provided.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: the deck that includes hull stem, hull afterbody and top, it is characterized in that the long L=130～180m of vertical line, molded breadth B=24～30m, speed of a ship or plane VS is 16～30 joints, underwater hull molded lines stem is provided with ball nose head, and the hull afterbody is provided with double tail fins.

By technique scheme, after the fore perpendicular of hull stem, in the long length range of 0.17L vertical line U type bench section is set, be than the bench section line style of flare greatly at hull stem 18 stations to the above water molded lines between 20 stations.

By technique scheme, adopted side hypertrophy, vertical profound double tail fins molded lines at the hull afterbody, the molded lines between the double tail fins is designed to pigeon breast shape.

The beneficial effects of the utility model are: 1, have outstanding resistance performance and propulsion quality, can normally navigate by water in the strong gale wave; 2, possess good rough water quality and road-holding property, enough intact stabilities and damaged stability are the further optimization to existing ro-ro passenger ship hull lines; 3,, proved the existence of above-mentioned hull characteristic by the tank test of little series.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, includes the hull stem, the hull stem adopts first post of bevelled and oval ball nose head, and oval ball nose head can provide enough lateral dimensions for the layout of former and later two first thrusters; In the long length range of 0.17L vertical line U type section lines is set after fore perpendicular, good rectification and directional tagging will be played in oval ball nose head and U type bench section; Is the section lines of big flare at hull stem 18 stations to the above water molded lines between 20 stations, has satisfied the operating needs of stem vehicle turnover on the one hand, also plays the effect of pressing wave on the other hand; The stem molded lines is the back nick linearly, and angle of attack is 12 °, has kept the outstanding waterplane shape of resistance performance.

The hull afterbody adopts square tail and asymmetric knuckle type double tail fins, described asymmetric knuckle type double tail fins is side hypertrophy, vertical profound tail fin shape, can realize the reasonable Arrangement of high-power main frame and gear case in the tail type cabin, this asymmetric knuckle type double tail fins structure is as attached body, take quite a few displacement of volume of hull afterbody, the prismatic coefficient of stern body is reduced, improve the wave making performance of hull tail end.At the speed range of this type ship, tail fin inclination angle and asymmetrical section are carried out

Optimal design, urosome side V-type body and knuckle type tail fin are combined to form the rectification cave of equivalent length, and the bench section of making up in a segment length in screw propeller the place ahead has U type feature, so just change the flow field state under the big situation of B/d (beam draft ratio), optimized the residuary resistance performance and the propulsion quality of afterbody.The bottom design of double tail fins centre portion body bench section becomes pigeon breast shape, by the guiding of this bottom shape to the bottom streamline, can guarantee the inboard water supply of screw propeller, improves the anti-oar effect of asymmetric knuckle type double tail fins to the outward turning oar.

The ship type of present embodiment has three layers of vehicle hold, four layers of superstructure, and the cabin is positioned at the rear portion, and tail end is established the tail watertight door and is vehicle springboard one cover; Hull top is provided with first, second two-

layer deck

1a, 2a, head end portion establishes first watertight door, first vehicle springboard, first guard shield one cover, establish a vehicle lifting platform and a movable car ramp that leads to upper-deck cabin that leads to the band water tight cover of hold for the ground floor deck 1a middle part of rolling the use of dress vehicle, the port and starboard stem is provided with passenger's side port, makes car visitor shunting.

Present embodiment hull length overall 161.2m, length between perpendiculars 147.0m, molded breadth 24.8m, designed draft 6.0 always carries car amount 5000t, staffing 1160 people, trial speed is 19.5 joints.
