specific Embodiment approach

[0045] Here, a small ship with bulbous flat steel as the longitudinal reinforcement member is taken as an example, such as figure 1 As shown, the box girder structure is improved, and the improvement is as follows figure 2 As shown, to improve the anti-knock and anti-shock performance of the ship, the specific implementation is as follows:

[0046] 1. Calculate the cross-sectional area of ​​the original ship

[0047] Draw the cross-sectional view of the hull according to the calculation software, and calculate the cross-sectional area including the longitudinal reinforcement members. If you are designing a new ship, you can skip this step if you are not improving the ship type.

[0048] 2. Determine the thickness and quantity of the box girder

[0049] According to the calculated cross-sectional area of ​​the original ship, the plate thickness of the box girder is allocated without exceeding this area, and the number of box girders and the plate thickness of the composite ...

Abstract

The invention aims at providing an anti-impact protection structure for box type beams of a hull. The anti-impact protection structure comprises box type beams, an upper deck, a lower deck and ship planking, wherein the box type beams are respectively arranged on the upper deck, the lower deck and the ship planking; the section of each box type beam is of a quadrilateral structure formed by an inner plate of the box type beam, an outer plant of the box type beam and two box type beam supporting plates, wherein the inner plate of the box type beam and the outer plate of the box type beam are opposite sides and the lengths of the opposite sides are a; the two box type beam supporting plates are opposite sides and the lengths of the opposite sides are b; the two box type beam supporting plates are respectively provided with connecting plates for connecting the upper deck, the lower deck and the ship planking; and the upper deck, the lower deck and the ship planking are made of composite materials. The anti-impact protection structure has the advantages of good intensity characteristic, good explosion-proof performance and high residual intensity, and is beneficial for reducing the weight of the hull, protecting important pipelines and cables, and improving construction speed, quality control and maintenance.

Description

technical field [0001] The invention relates to a hull structure in the field of ship design. Background technique [0002] The traditional shelf-type ship structure has been used for hundreds of years, and it has been proved to be a reliable structure form, but it is not necessarily the optimal hull structure form. In the construction industry, at first the construction of buildings was similar to that of ships, using integral brick-concrete structures, and all walls participated in the total strength, but later people discovered that the use of frame structures can not only reduce weight, but also have good seismic performance. It has many advantages such as high stability and toughness. From the perspective of bionics, the overall longitudinal strength of fish is only maintained by "strong beams" such as the spine, the lateral strength of fish is maintained by ribs, and the shape of fish is maintained by skin and flesh. Therefore, ship design can learn from the successf...
