Description
Technical field
The present invention relates to a kind of ship structure, particularly relate to a kind of side hull connection structure of trimaran.
Background technology
The trimaran lower apron is made up of middle body (main body) and two little lateral bodys (auxilliary hull); 3 hulls are elongated lamellar body; Middle body is than common single hull taller and thinner (L/B is greatly between 12 to 18); The lateral body displacement is no more than 10% of middle body displacement, and connecting bridge fuses lateral body and middle body.
This ship type structure makes the wave making resistance of high speed trimaran little, and (because each hull all is an asthenic, thereby the reduction wave making resistance especially might reduce at the popular wave resistance of high speed navigation significantly.Test shows, compares with single hull, and the elongated hull of tri-body ship type can reduce by 20% resistance, because resistance reduces, trimaran obtains the high speed of a ship or plane easily.); Two lateral bodys can provide enough stabilities again; Connecting bridge also has the function that improves longitudinal strength, also helps simultaneously to form broad deck plane, is the facility location greater room; The trimaran floor space is bigger by about 40% than single hull, can be the flight deck that carrier-borne aircraft (helicopter and unmanned plane) provides broad under the identical condition of displacement.
In addition, this ship type also has good rough water quality, especially can avoid " turn round and shake " (coupling of rolling and pitching is waved) and " suddenly shaking " (short-period rolling) of catamaran, and can obviously reduce pitching and heave.
The high speed trimaran also has protective capacities as army's ship, and (the every limit of main body has 1/3～1/2 length to be blocked by the side hull, when the anti-warship guided missle of being plunderred sea flight attacks, protection to a certain degree can be provided like this.), (because hull is elongated relatively, it is big that the distance between the propelling unit is wanted relatively, and current are just smaller to hull and angle of rake interference, and noise ratio is lower, has reduced the possibility that is detected by the other side's sonar significantly for damage stability and good concealment.In addition, the waste gas of main frame is introduced between three hulls and discharges, and can obviously reduce the infrared radiation signal on the ship.), be beneficial to advantages such as armament systems dispersed placement, modular design and helicopter operation.This ship type is suitable as multiple surface vessel, like high speed destroyer escort, destroyer, guided missile ship, submarine chaser etc., even has the people to think that the high speed trimaran is the potential ship type of following aircraft carrier, and its application prospect is quite wide.
In theory; Also there are some significant disadvantages in tri-body ship type; Like the structural strength problem, the wave interference problem between main body and the lateral body, comparing with conventional single hull also has complex structure; Weight is bigger, the shortcoming of manufacturing process complicacy, high, the following water of manufacturing cost, anchor bat and the comparison difficulty that lies up.
The research of high speed trimaran in recent years also begins to come into one's own at home.Late 1970s colleges and universities such as Shanghai Communications University and research institute almost begin simultaneously the ship type and the hydrodynamic force of high speed trimaran are studied, recognize that tentatively its wave making resistance, rough water quality aspect have big preceence.
The present age, the research of trimaran had nearly 30 years course; The research of high speed trimaran has just obtained bigger development after the mid-1970s; Research of high speed trimaran both at home and abroad mainly concentrates on aspects such as hydrodynamic theory, model test, the optimization of ship type and concept design during this, and a small amount of research about the structural strength aspect is also arranged.
The a series of remarkable advantages of multihull vehicle are that present high speed single hull can't be compared, and it all has tempting application prospect to Future Development ocean rapid transit boats and ships and military naval vessel.Boats and ships for delivery passenger, container cargo and vehicle require bigger floor space, and this just can give full play to multihull vehicle in the unique sorrow gesture of this one side.In addition, the navigation performance that multihull vehicle is good makes it to have the ability of competent numerous military missions.According to the data report, multihull vehicle can be used for following aircraft carrier, destroyer escort, minesweeper, anti-submarine vessel and fast traffic delivery ship etc.Abroad the someone points out, following aircraft carrier possibly adopt the catamaran type of small-waterplane-area, and the huge aircraft carrier of its tonnage and ship price ratio 10 tons is more reasonable.
Therefore, no matter be that civil transport or national defense and military are used, all with multihull vehicle as the new ship type of 21 century broad research in addition, this is just showing that it has great vitality and good prospects for application.
Though trimaran has as above advantage, it still exists and is further improved, the improvement part.
Lateral body and middle body relative position are for what fix at present, and the trimaran of each tonnage always is suitable for a certain specific load carrying ability especially, is suitable in some stormy waves ranks; Navigate by water under the sea situation of stormy waves direction, yet the adjustment of tonnage can solve; Ballast tank is arranged in boats and ships; Can regulate through the size of the ballast water yield, but the stormy waves rank, and the stormy waves direction is when navigation outwardness; Can't change, how to let trimaran can adapt to different stormy waves better is to be born and to be the puzzled difficult problem of shipping industry along with trimaran always.
