Abstract
The present utility model discloses a shock resistance boat bottom structure and pertains to the technical field of shipping shipping manufacturing. The shock resistance boat bottom structure consists of combination type stringers and angle steel shaped boat bottom longitudinal frames that are distributed equally and are connected with an outer bottom board and an inner bottom board, one combination type stringer comprises a vertical plate with the top end connected with the top edge of a top semi-sphere tube filled with materials and the top edge of a bottom semi-sphere tube filled with materials, two end-faces of the top semi-sphere tube of the stringer is connected with the inner bottom board, and the two end-faces of the bottom semi-sphere tube of the stringer is connected with the outer bottom board. The shock resistance boat bottom structure has impact loading capabilities of collision bearing, running aground bearing, underwater burst bearing and the like, and compared with the prior art, the shock resistance boat bottom structure is capable of protecting the inner structure, freights and shipborne apparatuses of ships well.
Description
Technical field:
The utility model belongs to the shipbuilding technical field, relates to a kind of bottom structure, or rather, relates to a kind of shock resistance double bottom skeleton structure.
Background technology:
In recent years, along with the development of world commerce, the seat transport industry is flourishing day by day, and all kinds of ship collisions such as oil carrier and grounding accident happen occasionally, and bring serious threat often for the security of the lives and property and ecology environment; Especially for army's ship, the underwater blast impact load can cause naval vessel bottom construction damage, influences the fighting capacity and the survivability on naval vessel.How improving particularly bottom of ship shock resistance of ship structure effectively, is that modern ships manufactures and designs problem demanding prompt solution in the process.
Though existing standard must be provided with the requirements such as safety that double bottom improves boats and ships to having stipulated such as large ships such as oil carriers, but traditional double bottom structure form adopts flat bottom girder, stringers of being made by a block plate and tank top plate and Outer Bottom Plating are supported between the two mutual vertically, when hull bottom is subjected to as stranded, during impact loads such as underwater blast wave, because dull and stereotyped stringers rigidity is bigger, it absorbs the impact energy poor effect, relatively poor to buffer action that rise at the end in the boats and ships, at stringers and tank top plate and Outer Bottom Plating intersection generation stress concentration and shearing stress, stringers often takes place to be broken up tank top plate and then causes crude oil leakage, the boats and ships water inlet, destroy accidents such as internal unit, so be necessary doing further research and improvement aspect the bottom of ship version.
Summary of the invention:
Technical matters: because bottom girder is the important component that runs through full captain's degree direction in the bottom of ship structure, the impact resistance that improves bottom girder promptly can improve the impact resistance of whole hull bottom greatly, the purpose of this utility model is for solving the deficiency of traditional bottom girder, providing the shock resistance bottom structure that a kind of energy-absorbing effect is good, buffer capacity strong, be easy to make by version and the application composite material that changes bottom girder.
Technical scheme: for achieving the above object, the technical scheme that the utility model adopted is: a kind of shock resistance bottom structure, form by some rectangular distributions and with compound type stringers 1 and angle steel shape bottom longitudinal 4 that Outer Bottom Plating 2 is connected with tank top plate 3, it is characterized in that: described compound type stringers 1 is made up of with the stringers riser 1-2 that the apical margin of the apical margin of the stringers top semicircle pipe 1-1 that is filled with packing material 1-4 and the stringers bottom semicircular pipe 1-3 that is filled with packing material 1-4 is connected respectively upper and lower side, two end faces of wherein said stringers top semicircle pipe 1-1 are connected with tank top plate 3, and two end faces of stringers bottom semicircular pipe 1-3 are connected with Outer Bottom Plating 2.
The radius of the radius of the stringers top semicircle pipe 1-1 of the above, the height of stringers riser 1-2, stringers bottom semicircular pipe 1-3, three's optimum dimension ratio is 1: 2.5: 1.
The above be connected to welding.
The packing material 1-4 of the above is an elastic rubber material.
Beneficial effect: a kind of shock resistance bottom structure of the present utility model is compared with the conventional ship bottom structure, and its advantage and beneficial effect are:
(1) when hull bottom meets with impact load, the semicircle pipe of stringers top and bottom deforms and increases energy-absorbing effect greatly, when the semicircle pipe produces certain distortion, be filled in its in-to-in elastic caoutchouc and will begin to bring into play buffer action, further absorb dump energy, the impact load energy is absorbed by the member below the boats and ships tank top plate in advance, can reduce the destruction to tank top plate, thus protection boats and ships internal unit and cargo security;
(2) elastic caoutchouc of closely knit filling makes stringers and tank top plate that bigger area of contact be arranged, and helps making the load on the stringers to be delivered to uniformly on the tank top plate, reduces the destruction that stress concentration brings.
Table 1 is to use energy absorption, acceleration/accel, deflection comparison on the tank top plate under common stringers and two kinds of situations of shock resistance stringers under the same impact load, and the three has reduction in various degree, illustrates to use the boats and ships double bottom of shock resistance stringers to help improving shock environment.
Table 1 uses parameter variation on the tank top plate of shock resistance bottom girder front and back
| Energy absorption (J) | Acceleration/accel (m/s 2) | Deflection (cm) | |
| Use common stringers | 0.33×10 6 | 1.9×10 4 | 6.21 |
| Use the shock resistance stringers | 0.054×10 6 | 1.21×10 4 | 2.28 |
Description of drawings:
Fig. 1 is a kind of shock resistance bottom structure drawing in side sectional elevation of the present utility model:
Among the figure: 1. compound type stringers, 2. Outer Bottom Plating, 3. tank top plate, 4. bottom longitudinal, 5. side plate, 1-1. stringers top semicircle pipe, 1-2. stringers riser, 1-3. stringers bottom semicircular pipe, 1-4. packing material.
The specific embodiment:
The utility model embodiment is: alow in the sectional construction process, mainly be the manufacturing of compound type stringers 1 with the difference of common ship double bottom manufacturing process, at first bend the semicircle pipe of corresponding size radius with steel plate, need to guarantee that stringers top semicircle pipe 1-1 radius, stringers riser 1-2 height, stringers bottom semicircular pipe 1-3 radius three ratio are 1: 2.5: 1 according to the size of actual ship dimensions; To use the closely knit filling of packing material 1-4 in stringers top semicircle pipe 1-1 and the stringers bottom semicircular pipe 1-3 then, and guarantee that packing material 1-4 and steel plate leak-tight joint do not come off; With the root edge welding of stringers riser 1-2 top with the stringers top semicircle pipe 1-1 that is full of packing material, the apical margin welding of stringers riser 1-2 bottom and the stringers bottom semicircular pipe 1-3 that is full of packing material forms compound type bottom girder 1 one; With two end faces and tank top plate 3 welding of compound type stringers top semicircle pipe 1-1, two end faces of stringers bottom semicircular pipe 1-3 weld with Outer Bottom Plating 2.
Subsequent process can carry out successively according to traditional bottom of ship sectional construction method, finally forms complete bottom of ship structure.
