Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a design method, device, equipment and medium for a flexible pipe of a ship's sea communication system. Background Art

[0002] With the development of larger and faster ships, safety and reliability have become crucial considerations in ship design and manufacturing. Sea pipes are typically used to introduce cooling seawater or discharge wastewater. Due to differences in ship draft, hull deformation varies. Therefore, flexible pipes are often added to sea pipes to compensate for this deformation and prevent fractures at the welds between the sea pipe and the hull.

[0003] Current designs for seagoing flexible nozzles typically rely on historical experience to determine displacement compensation parameters, making it difficult to design a flexible nozzle with an appropriate displacement compensation index. Excessively large displacement compensation increases costs and results in insufficient rigidity and pressure-bearing capacity. Excessively small displacement compensation can lead to axial or radial deviations during operation, creating a risk of fracture. Summary of the Invention

[0041] Figure 2 The following is a flow chart of a method for designing a flexible pipe for a ship's seagoing system according to an embodiment of the present invention. Figure 2 As shown, a flexible pipe design method for a ship sea-going system is provided, and the flexible pipe design method for a ship sea-going system is applied to Figure 1 The ship sea communication system in FIG. 1 is used as an example to illustrate the method, which includes the following steps: step 210, step 220, and step 230. The method flow steps are only a possible implementation of the present invention.

[0042] Step 210: Construct a static model of the hull based on finite element analysis software.

[0043] Among them, finite element analysis software is a computational tool used to solve mechanical problems of complex engineering structures and physical phenomena; finite element analysis software can simulate and analyze the physical properties of structures such as stress, deformation, heat conduction, and electromagnetic fields.

[0044] Optionally, the hull shell is geometrically modeled based on the overall shape of the hull, various details and features of the hull structure, such as the curvature and sheer of the hull.

[0045] In some embodiments, step 210 constructs a static model of the hull based on finite element analysis software, including:

[0046] Step 211: Model each module of the hull and determine the outline shape and basic size of each module;

[0047] Step 212: Assemble the models of the modules to obtain a hull installation model;

[0048] Step 213: construct a static model of the hull shell based on the hull installation model.

[0049] Optionally, the hull includes modules such as a bow, a stern, and a mid-hull.

[0050] Optionally, the modules are combined according to the designed assembly sequence and method to form a hull installation model.

[0051] Optionally, the geometric model of the hull shell is divided into small finite element units to facilitate subsequent static analysis.

[0052] In some embodiments, assembling the models of the modules to obtain a hull installation model includes:

[0053] Position each module and set constraints between modules to eliminate the degrees of freedom of each module.

[0054] Optionally, each module is positioned based on design specifications or manufacturing process requirements to ensure that the final assembled hull installation model has a correct shape and size.

[0055] It should be noted that constraints are rules or restrictions defined in finite element analysis software to ensure that each module does not move or deviate from the designed position during the assembly process.

[0056] Optionally, the constraints include fixed points, supports in fixed directions, matching of geometrical docking surfaces, etc. These constraints can ensure that the assembled hull model is mechanically stable and realistic.

[0057] Step 220: Based on the statics model of the hull, the deformation of the hull at different drafts is simulated to obtain different expected displacement compensation amounts of the flexible nozzle.

[0058] Optionally, the static model of the hull shell is imported into the finite element analysis software, and the water flow and load conditions at different drafts are considered to simulate the deformation of the hull shell at different drafts. According to the simulation results, the hull deformation at different drafts is determined to obtain different expected displacement compensation amounts of the flexible nozzle.

[0059] In some embodiments, step 220 simulates the deformation of the hull at different drafts based on a static model of the hull to obtain different expected displacement compensation amounts of the flexible pipe, including:

[0060] Step 221: define the mechanical properties of the hull and the sea pipeline;

[0061] Step 222: Determine the loads applied to the hull and the seagoing pipeline at different drafts;

[0062] Step 223: Perform mechanical analysis to calculate the deformation of the weld between the hull and the seagoing pipeline at different drafts;

[0063] Step 224: Determine different expected displacement compensation amounts of the flexible pipe based on the deformation amounts of the weld at different drafts.

[0064] Optionally, the properties of the materials used for the hull and the sea pipeline are defined, such as elastic modulus, Poisson's ratio and density, and the geometric properties of the hull and the sea pipeline are defined, such as size, shape and wall thickness.

[0065] Optionally, the buoyancy, gravity, hydrodynamic and other loads applied to the hull and the seagoing pipeline at different drafts are determined.

[0066] Optionally, the hull and the sea-going pipeline are meshed, and finite element analysis software is used to solve the static equations of the hull and the sea-going pipeline at different drafts to obtain the displacement, strain, and stress distribution of each node, and determine the deformation of the weld between the hull and the sea-going pipeline at different drafts.

[0067] It can be understood that by defining the mechanical properties of the hull and the sea-going pipeline, the accuracy and reliability of the simulation results can be ensured. By determining the loads applied to the hull and the sea-going pipeline at different drafts, the simulation process can be ensured to be close to the actual operating conditions. Through mechanical analysis, the deformation of the weld between the hull and the sea-going pipeline at different drafts can be calculated. Based on the deformation of the weld at different drafts, the different expected displacement compensation amounts of the flexible nozzle can be determined, thereby providing a comprehensive and accurate data basis for the optimized design of the flexible nozzle.

[0068] Step 230: Determine an optimal displacement compensation index of the flexible pipe based on different expected displacement compensation amounts of the flexible pipe.

[0069] Optionally, the optimal displacement compensation index of the flexible nozzle is determined by comprehensively considering the following aspects:

[0070] 1) Minimizing structural deformation: The design goal of the flexible nozzle is to reduce deformation at the welds between the hull and the seagoing pipeline by compensating for displacement. The optimal displacement compensation should be able to effectively reduce these deformations and maintain the stability and strength of the structure.

[0071] 2) Stress distribution of flexible pipes: The amount of displacement compensation will affect the stress distribution inside the flexible pipe. The optimal displacement compensation should be able to distribute stress as evenly as possible while reducing structural deformation, avoiding stress concentration and thus extending the service life of the flexible pipe.

[0072] 3) Flexible nozzle adaptability: The optimal displacement compensation should be able to remain effective under different drafts and operating conditions. This means that the design needs to take into account the deformation of the ship under different water depths and load conditions and ensure that the flexible nozzle can stably provide the required displacement compensation;

[0073] 4) Cost and manufacturing feasibility: The optimization of displacement compensation also needs to take into account manufacturing costs and technical feasibility. Designs that are too complex or expensive may not be practical. Therefore, the optimal design should simplify and optimize the manufacturing process as much as possible while meeting performance requirements.

[0074] In some embodiments, step 230 determines an optimal displacement compensation index for the flexible pipe based on different desired displacement compensation amounts for the flexible pipe, including:

[0075] Step 231: determining a maximum displacement compensation amount from different expected displacement compensation amounts of the flexible pipe;

[0076] Step 232: Determine the optimal displacement compensation index of the flexible pipe based on the maximum displacement compensation amount.

[0077] Optionally, based on the static model of the hull, the hull is analyzed at different draft depths ( ), the deformation of the hull shell at the welding point with the sea pipeline ( ), thereby determining the required displacement compensation amount of the flexible pipe ( ).

[0078] It can be understood that by determining the maximum displacement compensation amount from the different expected displacement compensation amounts of the flexible pipe, and based on the maximum displacement compensation amount, determining the optimal displacement compensation index of the flexible pipe, it can be ensured that the flexible pipe can provide sufficient displacement compensation under different environmental conditions and maintain structural strength and stability in actual applications, which can reduce the manufacturing cost of the flexible pipe and extend its service life.

[0079] In some embodiments, the calculation formula for the optimal displacement compensation index of the flexible pipe is as follows:

[0080] ;

[0081] in, represents the optimal displacement compensation index, Indicates different expected displacement compensation amounts.

[0082] Optionally, considering the simulation error, 1.2 times of the maximum displacement compensation amount is taken as the optimal displacement compensation index.

[0083] In an embodiment of the present invention, a static model of the hull shell is constructed based on finite element analysis software; based on the static model of the hull shell, the deformation of the hull shell at different drafts is simulated to obtain different expected displacement compensation amounts of the flexible pipe; based on the different expected displacement compensation amounts of the flexible pipe, the optimal displacement compensation index of the flexible pipe is determined, which can effectively avoid the displacement compensation index of the flexible pipe being too large, resulting in waste and pressure risk, and can also avoid the displacement compensation index of the flexible pipe being too small, causing axial or radial tolerance problems during operation and causing fracture risks, thereby ensuring the safe operation of the ship's sea connection system.
