[0042] The present disclosure is further described below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0043] Prefixes such as "first" and "second" are used in the embodiments of the present disclosure only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of prefixes such as ordinal numbers to distinguish description objects in the embodiments of the present disclosure does not constitute a limitation on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and no unnecessary limitation should be constituted due to the use of such prefixes. In addition, in the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0044] Commonly used hull structural steels include general strength steel (Grade A, B, D, E) plates and high strength steel (Grade AH32, DH32, EH32, AH36, DH36, EH36) plates specified in GB712; high-quality carbon steel (CIO, C20) pipes for ships specified in GB5312; and Grade A and B steel bulb flat steels for shipbuilding specified in GB9945.

[0045] Generally, the steel used for hull structure is divided into 4 grades: A, B, D, and E. The yield strength (not less than 235N / mm^2) and tensile strength (400-520N / mm^2) of these 4 grades of steel are the same, but the impact energy at different temperatures is different;

[0046] High-strength steel for hull structures is divided into strength grades according to its minimum yield strength, and each strength grade is further divided into four grades: A, D, E, and F according to its impact toughness.

[0047] A, D, E, and F represent the impact toughness that can be achieved at 0°, -20°, -40°, and -60°, respectively;

[0048] The yield strength of A32, D32, E32 and F32 is not less than 315N / mm 2 , tensile strength 440~570N / mm 2 ,

[0049] The yield strength of A36, D36, E36 and F36 is not less than 355N / mm 2 , tensile strength 490~620N / mm 2 ,

[0050] The yield strength of A40, D40, E40 and F40 is not less than 390N / mm 2 , tensile strength 510~660N / mm 2 .

[0051] Example 1

[0052] This embodiment provides an analysis method for selecting ship-shaped steel plates. Figure 1As shown, the analysis method comprises:

[0053] S101, obtaining the steel plate thickness of the ship type to be analyzed;

[0054] S102, in response to the thickness of the steel plate being less than a first preset thickness, selecting a grade A steel plate;

[0055] S103, in response to the thickness of the steel plate being greater than a second preset thickness, selecting an integer steel plate;

[0056] The integer steel plate is a steel plate having a thickness in units of integer millimeters.

[0057] In this scheme, the data differences in the ship type. Mainly reflected in the selection of steel plate thickness material and steel plate specifications, the first preset thickness can be 15mm. When the steel plate thickness is low, high-strength marine steel in grade A steel is selected, which has a higher yield strength. It not only reduces the overall weight of the ship, but also enhances the safety of the ship during shipping; the second preset thickness can be 50mm. The thicker the plate thickness, the numerical yield strength value of the steel plate thickness of 0.5 is obviously negligible. From a cost perspective, it can be completely replaced by integer steel plates, which can greatly reduce the number of steel plate thickness specifications. Under the premise of balancing production and procurement, the plate thickness can be merged. It is conducive to the control of cost engineering.

[0058] As an achievable manner, the analysis method further includes:

[0059] Obtain the steel plate specifications used in the ship type to be analyzed;

[0060] In response to the steel plate specifications including AH32 steel plate, the corresponding AH32 steel plate is replaced with AH36 steel plate.

[0061] In this solution, AH36 steel plates are used as much as possible to replace AH32 steel plates, which can significantly improve the strength, toughness and ability to resist harsh environments of ship engineering structures. Although the cost may be slightly higher, in the long run, this replacement can improve safety and service life, reduce maintenance costs, and thus is economically cost-effective.

[0062] As an achievable manner, the analysis method further includes:

[0063] Obtaining the steel plate distribution concentration in the ship type to be analyzed;

[0064] In response to the steel plate distribution concentration being higher than a preset concentration threshold, adjusting the steel plate step threshold in the ship type to be analyzed so that the steel plate distribution concentration is lower than the preset concentration threshold;

[0065] A first step length threshold is obtained based on the adjusted steel plate step length threshold, and the available steel plate specifications of the ship type to be analyzed are adjusted according to the first step length threshold.

[0066] In this scheme, whether the distribution of steel plates in the ship type to be analyzed is reasonable is judged by the concentration of steel plate distribution. For unreasonable steel plate layout, the step length of the steel plate is adjusted to adjust the length and width size requirements of the steel plate, and the optional number of steel plate specifications is compressed, which provides a large improvement space for procurement, assembly and subsequent production operations, and for the design of the ship type to be analyzed, so as to achieve good upgrade benefits.

[0067] As an achievable manner, in response to the thickness of the steel plate being greater than the second preset thickness, the step of selecting an integer steel plate includes:

[0068] Layering the integer steel plates based on a first preset interval;

[0069] Wherein, the first preset interval is greater than 2 mm;

[0070] Each layer of the integer steel plates adopts a grade A steel plate having a strength greater than a preset strength.

[0071] In this solution, by increasing the layer spacing for thicker steel plates, the stress concentration points caused by layering can be reduced, thereby reducing the risk of damage caused by stress concentration. A larger layer spacing helps to improve the internal structure of the steel plate, making it exhibit better toughness when subjected to alternating stress, thereby extending the service life of the steel plate. It can also reduce fatigue sources caused by internal defects, enhance the fatigue resistance of the steel plate, and enable it to maintain good performance under long-term heavy load environments.

[0072] As an achievable method, in response to the thickness of the steel plate being less than the first preset thickness, the grade A steel plate is selected.

[0073] Layering the integer steel plates based on a second preset interval;

[0074] Wherein, the second preset interval is less than 0.5 mm;

[0075] Each layer of the integer steel plates adopts a grade A steel plate having a strength greater than a preset strength.

[0076] In this solution, by reducing the layer interval, the stress concentration points can be reduced, the risk of damage caused by stress concentration can be reduced, and the overall strength and stability of the steel plate can be improved. The A-grade steel plate with a strength greater than the preset strength includes AH36 steel plate.

[0077] As an achievable manner, the analysis method further includes:

[0078] Obtaining the number of steel plates in the ship type to be analyzed;

[0079] In response to the number of steel plates being higher than a preset number threshold, adjusting the first step length threshold so that the number of steel plates is lower than the preset number threshold;

[0080] A second step length threshold is obtained based on the adjusted first step length threshold, and the available steel plate specifications of the ship type to be analyzed are adjusted according to the second step length threshold.

[0081] In this plan, the rationality of steel plate usage in ship design is analyzed by the number of steel plates. After reducing the number of steel plates, the optional number of steel plate specifications is compressed, which provides a large improvement space for procurement, assembly and subsequent production operations, and for the design of the ship type to be analyzed, so as to achieve good upgrade benefits.

[0082] The analysis method for selecting ship steel plates provided in this embodiment analyzes and adjusts the steel plate design scheme in the ship design based on the steel plate thickness and steel plate specifications, so that the ship design can adapt to the ever-changing technology and market environment and meet the needs of higher performance, longer life and lower cost.
