Embodiment Construction
[0018] like figure 1 and figure 2 The shown anti-rotation deformation structure of a vehicle ro-ro ship includes several double-hull anti-torsion boxes 1-4 arranged on both sides of the hull, and the double-hull anti-torsion boxes 1-4 are evenly arranged on the freeboard deck and Between the double bottom 9 and extending along the length of the hull, the double-hull torsion-resistant box 1-4 gradually widens from top to bottom along the vertical direction of the hull, and the double-hull torsion-resistant box 1-4 is formed by the outer plate 5. Each deck, longitudinal bulkheads 6-8 and corresponding frames are combined.
[0019] As a further optimization of the above technical solution, the longitudinal bulkhead is made of AH36 high-strength steel with a yield strength of 355MPa, and the thickness of the longitudinal bulkhead plate increases gradually from top to bottom. The vertical width of the double-shell torsion-resistant box gradually widens from top to bottom. The d...

The invention discloses a torsional deformation preventing structure and technological method for a car roll-on-roll-off ship. The torsional deformation preventing structure comprises a plurality of double-shell torsion boxes arranged on the two sides of a ship body, wherein the double-shell torsion boxes are evenly arranged between a freeboard deck and a double sole and extend in the length direction of the ship body, the double-shell torsion boxes become wider gradually from top to bottom in the vertical direction of the ship, and each double-shell torsion box is composed of a planking, a deck, a longitudinal bulkhead and corresponding aggregate. According to the torsional deformation preventing structure, the side structure below the freeboard deck is reinforced, a double-shell structure mode is adopted, the rigidity of a ship structure is improved, the torsion box effect is achieved, and due to the fact that the closer to a base line a portion is, the larger the external load borne by the portion is, the torsion boxes are designed to become wider gradually from top to bottom; the torsional deformation generated due to asymmetrical stress of a left board and a right board when the car roll-on-roll-off ship conducts rolling can be effectively controlled, and the structural strength of the car roll-on-roll-off ship can be improved.
Description
technical field [0001] The invention belongs to the technical field of ship design, and in particular relates to a structure and a process method for controlling the torsional deformation of a vehicle ro-ro ship. Background technique [0002] In order to facilitate the loading and unloading of vehicles, the deck of the vehicle ro-ro ship (PCC ship) is generally designed to be open, that is, generally no transverse bulkhead is set. Although this can effectively improve the efficiency of loading and unloading vehicles on PCC ships, due to the lack of transverse bulkheads, the torsional strength of the hull structure will face great challenges. When the ship rolls, the hull structure is likely to be twisted and deformed due to the asymmetric force on the starboard and starboard sides, resulting in catastrophic consequences such as tearing of the deck structure. Therefore, it is necessary to propose a structural form to effectively control the torsional deformation of the PCC s...
