Description

Technical Field

[0001] The present application belongs to the technical field of ship design and manufacturing, and in particular, relates to a structural reinforcement design method, system, device and medium for ship mooring equipment. Background Art

[0002] Mooring is a common mooring method for ships. The ship is fixed to the pier, dock or adjacent ship by mooring equipment, or the ship is tied to a cable buoy in the mooring yard to ensure that the ship can carry out mooring operations safely and reliably.

[0003] Mooring equipment should not only ensure the regular mooring of ships, but also meet the emergency towing conditions of ships. In actual applications, ships will be moored in different ports and sea areas, and mooring equipment needs to be suitable for different environmental conditions. Therefore, in the design and manufacturing stage of ships, it is necessary to strengthen the structure of mooring equipment to effectively transfer mooring loads while improving the stability and safety of ships during mooring. The existing mooring equipment structure strengthening design method mainly relies on designers to arrange structural reinforcement components on mooring equipment and check the mooring equipment after structural reinforcement based on ship structure, comprehensive mooring equipment type, mooring equipment layout location and verification specification requirements, etc., which requires high design experience and design knowledge of designers. In addition, due to the large number of mooring equipment types and different verification specifications for mooring equipment under different working conditions and different mooring equipment layout locations, manual structural reinforcement design of mooring equipment one by one not only requires a lot of manpower costs, but also has low efficiency in obtaining structural reinforcement design solutions, which reduces the production and manufacturing efficiency of ships.

[0004] Based on this, how to quickly obtain structural reinforcement design solutions for mooring equipment while reducing labor costs to improve the production and manufacturing efficiency of ships is an important issue that needs to be solved urgently. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present application is to provide a structural reinforcement design method for ship mooring equipment, which is used to solve the problem that the existing structural reinforcement design method not only requires a large amount of manpower cost to obtain the structural reinforcement design scheme of the ship mooring equipment, but also has low efficiency in obtaining the structural reinforcement design scheme, thereby reducing the production and manufacturing efficiency of the ship.

[0006] To achieve the above-mentioned and other related purposes, the present invention provides a structural reinforcement design method for a ship mooring device, comprising the following steps:

[0007] Initial model acquisition: acquiring a reinforcement design model of the mooring equipment; the reinforcement design model is a model of the mooring equipment with reinforcement components arranged therein;

[0016] Without damaging the designed ship structure, the mooring equipment is structurally strengthened by using an alignment reinforcement method;

[0017] When the distance between the reinforcing member and other members is less than a preset distance threshold, increasing the installation inclination angle of the reinforcing member;

[0018] The installation inclination angle is inclined in a direction opposite to the other components; when the number of the reinforcing components that meet the structural reinforcement verification requirements is greater than 1, among the reinforcing components that meet the structural reinforcement verification requirements, the reinforcing component with the smallest size and the lowest assembly difficulty is selected to structurally reinforce the mooring equipment.

[0019] In one embodiment of the present invention, the current structural reinforcement verification result includes: the stress value of the currently reinforced mooring equipment under different working conditions, and the stress difference between the standard stress value of the mooring equipment under the corresponding working conditions; then satisfying the preset structural reinforcement verification requirements includes: the stress difference between the stress value of the currently reinforced mooring equipment under different working conditions and the standard stress value of the mooring equipment under the corresponding working conditions is greater than 0.

Based on the current structure reinforcement verification result, when the currently reinforced mooring equipment meets the preset structure reinforcement verification requirements, the current reinforcement design model is used as the final reinforcement design model of the mooring equipment. When the currently reinforced mooring equipment does not meet the preset structure reinforcement verification requirements, the current structure reinforcement design model is optimized and strengthened until the current structure reinforcement design model meets the preset structure reinforcement verification requirements. This not only reduces a lot of manpower cost investment, but also improves the efficiency of obtaining the structure reinforcement design scheme, thereby improving the production and construction efficiency of the ship.

[0073] See also Figure 1 , showing a schematic flow chart of a structural reinforcement design method for a ship mooring equipment provided by the present invention in one embodiment;

[0074] like Figure 1 As shown, in this embodiment, the structural reinforcement design method of the ship mooring equipment provided by the present invention comprises the following steps:

[0075] Step S1, obtaining a reinforcement design model of a mooring equipment;

[0076] The reinforced design model is a finite element simulation model of the mooring equipment in which the reinforcement components have been arranged, and the translation constraint at the model boundary of the reinforced design model is 0.

[0077] Optionally, at the model boundary of the enhanced design model, translation constraints in three directions, X, Y and Z, are all 0.

[0078] Optionally, the arrangement position of the mooring equipment is acquired based on a mooring equipment arrangement diagram of the mooring equipment.

[0079] Optionally, the reinforcement design model includes various structural components and extension areas in the mooring equipment; the extension area includes: a transverse strong member extending toward the bow at the structural member closest to the bow, a transverse strong member extending toward the stern at the structural member closest to the stern, and an area extending vertically from the deck where the mooring equipment is located to the next deck; the structural members include original members and reinforcement members of the mooring equipment; the original members include various members that constitute the mooring equipment before structural reinforcement; the reinforcement members include various members arranged on the mooring equipment during the structural reinforcement design process; exemplarily, the transverse strong member is a transverse strong member with longitudinal and transverse T rows.

[0080] In one embodiment, the method of constructing the enhanced design model includes:

[0081] Acquire an initial reinforcement layout diagram of the mooring equipment; based on the initial reinforcement layout diagram, use plate elements to construct a first model within a preset refinement area, use beam elements to construct a second model outside the preset refinement area, and acquire a model composed of the first model and the second model as the reinforcement design model;

[0082] The preset refinement area is an area preset in the initial reinforcement layout diagram for performing structural reinforcement refinement verification.

[0083] Optionally, both the first model and the second model are finite element simulation models.

[0084] Optionally, according to the IACS International Association of Classification Societies specifications, a virtual rod unit is added to the free edge of the finite element simulation model in the preset refinement area to verify the axial stress value of the free edge of the finite element model plate; preferably, the cross-sectional area of ​​the virtual rod unit is 0.1mm 2 .

[0085] Optionally, the grid in the reinforced design model adopts a first grid size, the aspect ratio of each unit is less than or equal to 3, and the height of the truss web unit is less than or equal to 1 / 3 of the height of the web unit; illustratively, the first grid size is 200 mm in length and width.

[0086] Optionally, when the mooring equipment in the preset refined area is structurally reinforced in an unaligned manner, the grid size in the preset refined area is set to a second grid size, and a corrosion allowance of 2 mm is deducted in the reinforced design model; the corrosion allowance is specified in the IACS International Association of Classification Societies specifications, and the hull surface is easily corroded by seawater, and the deduction portion needs to be considered; exemplarily, the second grid size is 50 mm in length and width.

[0087] Optionally, when performing force analysis and calculation on the mooring equipment in the area that needs to be checked, the result amplification criterion method and / or the fine grid average stress method may be used; in a specific embodiment, the fine grid average stress method is used to perform force analysis and calculation on the mooring equipment.

[0088] In this embodiment, the structural reinforcement design method of the ship mooring equipment provided by the present invention performs fine grid division on the area that needs to be checked in order to more accurately capture the local stress distribution; when the fine grid average stress method is used to perform force analysis and calculation on the mooring equipment, compared with the result magnification criterion method, the fine grid average stress method provides higher calculation accuracy, is independent of the specific classification society magnification criterion coefficient, and has high universality; and by averaging the stresses of 16 grids around a grid, not only can the stress state of the reinforced area be quickly evaluated, the design and verification process can be accelerated, and more real and reliable stress values ​​can be obtained, thereby more accurately evaluating the bearing capacity of the structure.

[0089] In one embodiment, the method for obtaining the initial reinforcement layout diagram includes:

[0090] Based on the arrangement position, stress value and force direction of the mooring equipment, combined with the standard stress values ​​of the mooring equipment under different working conditions, and in accordance with the structural reinforcement design principle, corresponding reinforcement components are arranged on the mooring equipment; based on the mooring equipment after the reinforcement components are arranged, an initial reinforcement arrangement diagram is obtained, and based on the force analysis principle, a verification area is selected in the initial reinforcement arrangement diagram.

[0091] Optionally, the structural reinforcement design principles include:

[0092] When the mooring equipment can meet the structural reinforcement verification requirements by adjusting the position and / or angle of the mooring equipment, the mooring equipment is structurally strengthened by adjusting the position and / or angle of the mooring equipment;

[0093] When the material of the mooring equipment is replaced so that the mooring equipment meets the structural reinforcement verification requirements, the mooring equipment is structurally strengthened by replacing the material of the mooring equipment;

[0094] Without damaging the designed ship structure, the mooring equipment is structurally strengthened by using an alignment reinforcement method;

[0095] When the distance between the reinforcing member and other members is less than a preset distance threshold, increasing the installation inclination angle of the reinforcing member; the other members are members other than the reinforcing member;

[0096] The installation inclination angle is inclined in a direction opposite to the other components; when the number of the reinforcing components that meet the structural reinforcement verification requirements is greater than 1, among the reinforcing components that meet the structural reinforcement verification requirements, the reinforcing component with the smallest size and the lowest assembly difficulty is selected to structurally reinforce the mooring equipment.

[0097] For example, Figure 2 As shown, when the mooring equipment 1 is arranged on the deck 2, the mooring equipment 1 includes a first reinforcing member 11 and a second reinforcing member 12. When the distance between the first reinforcing member 11 and the hull outer plate 3 is less than a preset distance threshold, the welding construction will be affected. Therefore, it is necessary to increase the installation inclination angle of the first reinforcing member 11 by 10°, and tilt the installation angle of the reinforcing member toward an area with a larger spatial range to increase the construction space and facilitate construction, and add an angle value of the installation inclination angle to the initial reinforcement layout diagram.

[0098] Step S2: Based on the current reinforcement design model, perform force analysis and calculation on the currently reinforced mooring equipment to obtain stress values ​​of the currently reinforced mooring equipment under different working conditions, and perform structural reinforcement verification on the currently reinforced mooring equipment in combination with the standard stress values ​​of the mooring equipment under different working conditions to obtain the current structural reinforcement verification result;

[0099] The structural reinforcement verification result includes: the stress value of the currently reinforced mooring equipment under different working conditions, and the stress difference between the standard stress value of the mooring equipment under the corresponding working conditions.

[0100] Optionally, by analyzing the composite stress and shear force of the plate unit, the stress of the beam unit and the axial stress of the free edge of the reinforcing member, the stress values ​​of the currently reinforced mooring equipment under different working conditions are obtained.

[0101] Optionally, the mooring equipment can be divided into: mooring equipment, towing equipment and / or emergency towing equipment according to its use; the calculation method of the standard stress value of the mooring equipment corresponds to the use of the mooring equipment. When the mooring equipment is the mooring equipment, the standard stress value of the mooring equipment is 1.15 times the safety allowable stress value of the mooring equipment; when the mooring equipment is the towing equipment, the standard stress value of the mooring equipment is 1.25 times the safety allowable stress value of the mooring equipment; when the mooring equipment is the emergency towing equipment, the standard stress value of the mooring equipment is 2 times the safety allowable stress value of the mooring equipment.

[0102] Exemplarily, the calculation method of the standard stress value of the mooring equipment is as follows:

[0103] F m =1.15×SWL

[0104] F t =1.25×SWL

[0105] F e =1.25×SWL

[0106] In the above formula, F m Indicates the mooring equipment; F t Indicates the towing equipment; F e represents the emergency towing equipment; SWL represents the safety allowable stress value of the mooring equipment.

[0107] Optionally, the mooring equipment includes: guiding equipment, mooring bollards, cleat rollers, mooring winches, anchor windlasses, chain stoppers and / or anchor abandoners, etc.; illustratively, the cable guide equipment includes: cable guide holes and / or cable guides, etc.

[0108] See also Figures 3 to 6 , respectively showing a schematic diagram of the force on the rope of the cable guide device, a schematic diagram of the force on the cable guide device, a schematic diagram of the force on the cable guide device in different rope output directions, and a schematic diagram of the force application point of the cable guide device;

[0109] Exemplarily, when the mooring equipment 1 is a cable guide equipment, Figure 3 and Figure 4 As shown, the mooring device 1 is affected by the pulling force F1 in the direction of the rope entering and the pulling force F2 in the direction of the rope leaving, and the force application point A of the mooring device 1 is the center point of the mooring device 1 or the contact point of the cable on the mooring device 1; Figure 4 As shown, Figure 4 Included Figure 4 a and Figure 4 b, Figure 4 a shows the force condition of the mooring device 1 observed on an observation plane parallel to the deck, Figure 4 b shows the stress condition of the mooring device 1 observed on the observation plane perpendicular to the deck. Since the rope entry angle α in the cable entry direction does not change, while the rope exit angle β in the cable exit direction changes with different working conditions, the tension F2 in the rope exit direction of the mooring device 1 will change accordingly; Figure 5As shown, it is a schematic diagram of the forces of the mooring device 1 in the first rope-out direction LC1, the second rope-out direction LC2, the third rope-out direction LC3, the fourth rope-out direction LC4 and the fifth rope-out direction LC5, wherein the first rope-out direction LC1 is 90° in the XOY plane, and the angle between it and the rope-in ​​angle is the smallest; the second rope-out direction LC2 is 45° rotated in the XOY plane; the third rope-out direction LC3 is 90° in the YOZ plane; the fourth rope-out direction LC4 is 45° rotated in the YOZ plane; the fifth rope-out direction LC5 is 45° in space; as shown Figure 6 As shown, the force application point A of the mooring device 1 is located at the contact point between the cable guide device and the cable.

[0110] See also Figures 7 to 9 , respectively showing the force diagram of the cable pile under the condition of double-column rope winding, the force diagram of the cable pile under the condition of cable winding on the reel, and the force action point diagram of the cable pile;

[0111] For example, when the mooring equipment 1 is a bollard, if there is a specific cable winding method on the mooring arrangement diagram of the mooring equipment 1, it is necessary to check the stress of the mooring equipment 1 under the rope winding condition and the figure-8 rope winding condition; Figure 7 As shown, when the mooring equipment 1 is in a double-column rope winding condition, the mooring equipment 1 is affected by the tension F1 in the rope entry direction and the tension F2 in the rope exit direction. If the mooring equipment 1 uses a double-column mooring bollard, the double-column mooring bollard should be able to withstand the stress generated by the mooring rope in the form of an 8-shaped winding. Under this condition, the mooring equipment 1 is only subjected to a resultant force along the axial direction of the mooring bollard. Therefore, it is necessary to check the stress under the rope winding condition and the 8-shaped rope winding condition.

[0112] If there is no specific cable winding method on the mooring arrangement diagram of the mooring equipment 1, and only one cable bollard is shown, the cable bollard does not play the role of cable guide, but only plays the role of fastening the free end of the cable. In this case, the cable bollard only needs to calculate an 8-shaped rope winding condition;

[0113] like Figure 8 As shown in FIG. 1 , if the mooring arrangement diagram of the mooring equipment 1 has a specific cable winding method, but the cable entry direction of the mooring equipment 1 is connected to the driving device, in this case, although the mooring pile is pulled by the cable in the cable entry direction, the cable connected to the driving device at the cable entry end is actually not subjected to force, and the cable only serves to recover the cable. In this case, only the tension F2 in the cable exit direction is considered in the force analysis calculation; Fig. 9As shown, the height H1 of the force application point A should be located at 4 / 5 of the height H of the cylinder above the base. When a baffle is installed on the cylinder, the height H1 of the force application point A is the height of the baffle. To ensure the accuracy of the structural reinforcement verification results, the height H1 of the force application point A is taken to be 4 / 5 of the height above the base. When actually calculating the loading, the height H1 of the force application point A is the vertical height from the force application point A to the deck 1, then H1 = (4 / 5)*H+h.

[0114] Optionally, the driving device includes a pneumatic winch or a reel.

[0115] Step S3, based on the current structural reinforcement verification result, detecting whether the currently reinforced mooring equipment meets the preset structural reinforcement verification requirements, if yes, obtaining the current reinforcement design model as the final reinforcement design model of the mooring equipment; if no, based on the current structural reinforcement verification result and according to the structural reinforcement design principle, performing optimization reinforcement design on the current structural reinforcement design model to update the current reinforcement design model, and re-executing steps S2 to S3;

[0116] Optionally, satisfying preset structural reinforcement verification requirements includes: stress differences between stress values ​​of the currently reinforced mooring equipment under different working conditions and standard stress values ​​of the mooring equipment under corresponding working conditions are both greater than 0.

[0117] It should be noted that when all the stress difference values ​​are greater than 0, it means that the currently strengthened mooring equipment meets the strengthening specifications under different working conditions.

[0118] In one embodiment, the optimization and enhancement design is implemented by:

[0119] Determine whether the position and / or angle of the currently reinforced mooring equipment can be adjusted so that the currently reinforced mooring equipment meets the structural reinforcement verification requirements. If so, adjust the position and / or angle of the currently reinforced mooring equipment so that the currently reinforced mooring equipment meets the structural reinforcement verification requirements; if not, obtain the stress difference value less than 0; based on the stress difference value, obtain each reinforcement component that meets the preset structural reinforcement verification requirements; among the reinforcement components that meet the preset structural reinforcement verification requirements, select the reinforcement component with the smallest size and the lowest assembly difficulty as the reinforcement component to be arranged; according to the structural reinforcement design principle, arrange the reinforcement component to be arranged on the currently reinforced mooring equipment.

[0120] Optionally, the designer may determine, based on his / her design experience, whether the position and / or angle of the currently reinforced mooring equipment can be adjusted so that the currently reinforced mooring equipment meets the structural reinforcement verification requirements.

[0121] In the above embodiment, a structural reinforcement design method for a ship mooring equipment is provided. By acquiring a reinforcement design model of the mooring equipment, based on the current reinforcement design model, a force analysis calculation is performed on the currently reinforced mooring equipment, and the force stress values ​​of the currently reinforced mooring equipment under different working conditions are obtained. In combination with the standard stress values ​​of the mooring equipment under different working conditions, the currently reinforced mooring equipment is structurally reinforced and checked. Based on the current structural reinforcement check result, when the currently reinforced mooring equipment meets the preset structural reinforcement check requirements, the current reinforcement design model is used as the final reinforcement design model of the mooring equipment. When the currently reinforced mooring equipment does not meet the preset structural reinforcement check requirements, the current structural reinforcement design model is optimized and reinforced until the current structural reinforcement design model meets the preset structural reinforcement check requirements. This not only reduces a large amount of manpower cost investment, but also improves the efficiency of obtaining structural reinforcement design solutions, thereby improving the production and construction efficiency of ships. In addition, the method can obtain the optimal mooring reinforcement form and material specifications, provides favorable technical support for actual production and construction, and ensures the safety of actual mooring operations.

[0122] like Fig.10 As shown, in this embodiment, the present invention provides a structural reinforcement design system for ship mooring equipment, including:

[0123] The initial model acquisition module 301 is used to acquire a reinforcement design model of the mooring equipment; the reinforcement design model is a model of the mooring equipment with reinforcement components arranged therein;

[0124] The structural reinforcement verification module 302 is used to perform force analysis and calculation on the currently strengthened mooring equipment based on the current reinforcement design model to obtain the stress values ​​of the currently strengthened mooring equipment under different working conditions, and perform structural reinforcement verification on the currently strengthened mooring equipment in combination with the standard stress values ​​of the mooring equipment under different working conditions to obtain the current structural reinforcement verification result;

[0125] The final model acquisition module 303 is used to detect whether the currently strengthened mooring equipment meets the preset structural reinforcement verification requirements based on the current structural reinforcement verification results. If so, the current reinforcement design model is obtained as the final reinforcement design model of the mooring equipment; if not, based on the current structural reinforcement verification results and according to the structural reinforcement design principles, the current structural reinforcement design model is optimized and strengthened to update the current reinforcement design model, and the structural reinforcement verification module and the final model acquisition module are re-executed.
