Description

Opening reinforcement modeling system and method of hull {STIFFENING MEMBER MODELING SYSTEM AND METHOD FOR OPENING OF HULL}

The present invention relates to a system and method for opening reinforcement modeling of a ship, and more particularly, to a system and method that can automatically model a reinforcement of a hole or notch of a ship hull regardless of position change. It is about.

In shipbuilding, the necessary equipment is installed and installed in various hole hull structures, and notches are installed to facilitate assembly or mounting during shipbuilding.

These holes and notches can make the hull unsatisfied with stress, which requires the construction of a double plate, which is a reinforcement or reinforcing member, to reinforce it.

A hole means a structure in the hull that has a hole in the form of a complete circle or a perfect ellipse.

Notch is a cause of stress concentration such as discontinuity of structure, material discontinuity between welding metal and base metal, and welding defect. The nonuniformity of the material, such as the edge during gas cutting, the weld heat affected zone, and the like, are a major cause of the notch.

Stress refers to the internal force generated in an object, that is, when an external force (for example, a wave force) is applied to an object, to resist the external force, and to maintain the shape of the object.

The stress increases with increasing external force, but there is a limit to the stress, so when the stress reaches its inherent limit, the material becomes irresistible and finally the material is destroyed.

Therefore, the construction of reinforcement in holes or notches considering stress in shipbuilding is an important part and a necessary process.

In order to model the reinforcement member, a process of modeling a panel by drawing a curve by hand in two dimensions according to the shape of a hole or notch has been required. However, this is required to change design equipment specifications or design equipment and hull structure. The initial shape and position of the hole or notch are frequently changed by the interference. In this case, the coordinate values and the shape of the two-dimensional curves that have already been constructed are different and cannot be used. As a result, the design time required to rewrite the shape of the changed hole or notch is high, and the error caused by constructing the curve by hand frequently causes design quality problems.

Steel construction pre-treatment (grinding to remove rust and painting to prevent rust) is carried to the processing plant by construction order.

Machining process 440 is made in the processing plant, such as marking, cutting, bending (molding).

The assembly work includes granulation and non-assembly processes, in which the members are assembled and welded to each other in the small assembly site to form blocks. When the block is completed, it is mounted as a large block that can be mounted on the crane, completes the watertight welding, and launches it into the fleet or dock.

Looking at the steel assembly process in detail, the small assembly process (441), which is the operation of assembling the members to each other, the plate assembly (block), the outer shell block, the superstructure block for assembling the small assembly and the small assembly Rib process, and the heavy assembly to form a three-dimensional block to form a three-dimensional block again to be mounted in the dock (dock) and a control assembly (442) that is a process of assembling the heavy assembly.

The preceding chair 430 refers to a process of pre-executing and mounting the equipment or pipe inside the block while the block is made.

Preloading (P.E) process 144 is a process of combining the block in a large block (block) to the extent that can be lifted by the crane before mounting the contrasted block in the dock.

Mounting step 445 is the final step of the hull construction to construct the overall form of the ship by automatic and manual welding of the blocks transferred in the assembly process in the fleet or dock.

The design work is carried out in parallel with the hull construction, and works such as the plumbing and plumbing work that attaches the main engine and various mechanical and electrical devices necessary for the operation of the ship to the hull, and connects the attached devices into one system, This includes the construction of crew's residential facilities and the work of painting the surface and inner surfaces of the hull to prevent rust.

The hull shell coating 450 is a process directly related to preventing corrosion of the hull by repeating the painting-drying-painting.

The launch 451 is a process of mounting a block in a dock-welding-hull completion-to discharge the ship from the dock.

The quayside 452 is a process of finishing the overall installation, such as installation, confirmation and inspection of the equipment, such as machinery, piping, electrical equipment is docked on the quay after launching.

The test run 460 individually tests the performance of various equipment installed on the ship according to the specifications required for the contract when the hull construction and the design construction are completed.

Mooring commissioning is the test of mooring on the quay, which refers to the commissioning of various equipment operations. Offshore commissioning tests the ship's speed, fuel consumption, maneuverability, main engine and propeller performance in the presence of the owner and the Society.

This test is called Sea Trial and must pass the test before it can be delivered to the owner.

The hull opening reinforcement modeling system and method in the present invention is part of the production design 422 process in FIG.

Double plate, which is a reinforcing material, is a plate that is used by overlapping with the main plate for bonding or reinforcement, and is also used as a laminate for bonding.

The curve means the shape of the edge of the double plate that is the reinforcement.

The reason why curves are important in double plate modeling is that proper reinforcement of stresses caused by holes or notches requires a double plate that accurately reflects the shape of the holes or notches. Or notches must accurately reflect the shape.

The lapping value refers to the width of the double plate being reinforced, and the lapping value varies according to the hole or notch size.
