[0043] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0044] Example 1

[0045] The method for bidirectional data conversion based on S3D-Mars in this embodiment is as follows: Figure 1 As shown, the method includes:

[0046] S11, obtaining the original data of the cross-section model corresponding to the S3D model; the original data of the cross-section model is used to represent the ship specification design data required for ship structure modeling;

[0047] S12, preprocessing the original data of the cross-section model to obtain cross-section model data;

[0048] S13, using the cross-section model data as input of the Mars model, and adjusting the cross-section model data until the Mars model reaches the set ship specification design standard, thereby obtaining the cross-section model target data;

[0049] S14, comparing the cross-section model data with the cross-section model target data, and adjusting the S3D model according to the comparison result.

[0050] For the above steps S11-S14, the plate frames and cabin objects of the whole ship are obtained from the database of the S3D model. The plate frames and cabin objects of the whole ship are traversed by longitudinal range traversal and screening. The cross-section position input by the user is judged. If the longitudinal range of the plate frame and cabin object contains the cross-section position, it is screened out as the original data of the cross-section model. The original data of the cross-section model of the plate frame, cabin and longitudinal bone connection node extracted from the S3D model are converted according to the modeling rule requirements of the Mars model. According to the characteristics of the Mars modeling, the following three rules are defined: (1) The order of the plate frames is arranged according to "outer bottom-bilge-side-deck-longitudinal bulkhead-inner bottom-inner shell-longitudinal girder-horizontal girder"; (2) The extension direction of the plate frame is defined from the center of the ship to the side and from the bottom to the top; (3) The starting node of each plate frame is used as the reference point. Write the converted cross-section model data into a text document, and automatically change the text document suffix to ".ma2" to realize the data input of the Mars model. Use the cross-section model data generated in the S3D-Mars data conversion as the input data of the Mars model, run the Mars model calculation analysis, optimize and modify the model according to the analysis results, and use the modified Mars model as the cross-section model target data. By comparing the cross-section model target data and the cross-section model data, the model modification data is identified, and according to the modification data, the corresponding model object data in the S3D model is reversely located and automatically updated.

[0051] In this embodiment, the data of the connection nodes of the plate frame, cabin and longitudinal bone contained in a certain cross-section position of the S3D model are converted into the input data of the Mars model; the S3D model is automatically updated according to the modified data of the strake, frame and plate seam of the Mars model after calculation and optimization. The process of repeated modeling and modification is omitted, and the modeling operation efficiency of designers is improved.

[0052] In one embodiment, Figure 2 As shown, step S12 includes:

[0053] S121. Analyze the original data of the cross-section model to obtain strake data, frame data, node data, cabin data and bracket data;

[0054] S122. Convert the data formats of strake data, frame data, node data, cabin data and bracket data respectively to obtain cross-section model data in a file data format corresponding to the Mars model.

[0055] Wherein, step S121 specifically includes:

[0056] Convert the list width data in the column plate data into the plate seam position data, convert the node data in the form of first connected in the order of plate rack data into the form of marked node number, convert the cabin boundary plate rack data in the cabin data into cabin node composition data, and convert the combined bracket arrangement type in the bracket data into the longitudinal bone end connection;

[0057] Map the data format corresponding to the bone coordinates, dimensions and materials of the bone data.

[0058] The specific preprocessing process is as follows: sort the nodes of each plate frame according to the order of plate frame arrangement and define the node serial number. The data of the column plates and frames on the frame are sorted with the starting node of the frame as the reference point and the extension direction of the frame as the condition. According to the composition of the cabin boundary frame, select the characteristic nodes of the boundary frame, record the serial number of the node, and combine the node serial numbers in the counterclockwise direction of the cabin boundary as the node composition of the cabin. The column plates, frames and cabin data are directly mapped according to the rules in Mars. The longitudinal bone connection node data mainly includes two parts: the connection form of the longitudinal bone end and the distance from the fatigue hot spot to the nearest end of the span. The connection form of the longitudinal end is converted by combination and matching. The type and arrangement of the bracket connected to the longitudinal at the strong frame are combined and matched one by one with the longitudinal connection form included in Mars. The distance from the fatigue hotspot to the nearest end of the span is calculated by creating a translation surface. According to the requirements of the CSR specification, a plane with a distance from the longitudinal wing plate surface of 1 / 2 the total height of the longitudinal is established to obtain the length of the intersection line with the bracket, and the value is calculated by combining the end connection form.

[0059] In one embodiment, Figure 3 As shown, step S14 includes:

[0060] S141, comparing the cross-section model data with the cross-section model target data, and determining the strake thickness data, frame size data, plate seam displacement data, and frame displacement data that are different;

[0061] S142. Update corresponding data in the S3D model according to the different column plate thickness data, frame size data, plate seam displacement data and frame displacement data.

[0062] Specifically, read the original file corresponding to the cross-section model data and the modified file corresponding to the cross-section model target data row by row, and record all the data contained in the data headers "STRAKES", "STIFF LOC" and "STIFF SCANT". Compare the data row by row, and filter out the modified data in the strake thickness data, frame size data and plate seam displacement data. Record the modified strake position, thickness and width data, frame position, size and type data.

[0063] The S3D model is matched with the Mars model one by one, and the S3D model objects that need to be updated are located according to the position information in the strake and frame modification data. The strake thickness and frame size are updated by directly modifying the object attribute values ​​of the S3D model. According to the position information in the frame modification data, a new position plane is established in the S3D model, and a new frame is created at the position plane using the Sketch2D drawing method, and then the unnecessary frame is deleted, so that the frame position can be updated. The S3D model is adjusted according to the above method.

[0064] In this embodiment, the cross-section model raw data corresponding to the S3D model is preprocessed to obtain cross-section model data that meets the input specifications of the Mars model, and the S3D model is updated by comparing the cross-section model target data and the cross-section model data, which greatly shortens the modeling and model modification time and significantly improves the ship modeling efficiency; and the data conversion is based on a single data source, eliminating human modeling errors and significantly improving the quality of ship design.

[0065] Example 2

[0066] The system of the present embodiment based on the bidirectional conversion of data of S3D-Mars is as follows: Figure 4 As shown, the system includes:

[0067] The acquisition module 310 is used to acquire the original data of the cross-section model corresponding to the S3D model; the original data of the cross-section model is used to represent the ship specification design data required for ship structure modeling;

[0068] A preprocessing module 320 is used to preprocess the original data of the cross-section model to obtain cross-section model data;

[0069] An input module 330 is used to use the cross-section model data as input of the Mars model, and adjust the cross-section model data until the Mars model reaches the set ship specification design standard, thereby obtaining the cross-section model target data;

[0070] The adjustment module 340 is used to compare the cross-section model data with the cross-section model target data, and adjust the S3D model according to the comparison result.

[0071] The acquisition module 310 obtains the plate frame and cabin objects of the whole ship from the database of the S3D model, and traverses the plate frame and cabin objects of the whole ship by longitudinal range traversal and screening. It determines according to the cross-section position input by the user. If the longitudinal range of the plate frame and cabin object contains the cross-section position, it will be screened out as the original data of the cross-section model. The pre-processing module 320 converts the original data of the cross-section model of the plate frame, cabin and longitudinal bone connection node extracted from the S3D model according to the modeling rule requirements of the Mars model. According to the characteristics of the Mars modeling, the following three rules are defined: (1) The order of the plate frame is arranged according to "outer bottom-bilge-side-deck-longitudinal bulkhead-inner bottom-inner shell-longitudinal girder-horizontal girder"; (2) The extension direction of the plate frame is defined from the center of the ship to the side and from the bottom to the top; (3) The starting node of each plate frame is used as the reference point. The converted cross-section model data is written into a text document, and the extension of the text document is automatically modified to ".ma2" to realize the data input of the Mars model. The preprocessing module 320 uses the cross-section model data generated in the S3D-Mars data conversion as the input data of the Mars model, runs the Mars model calculation analysis, optimizes and modifies the model according to the analysis results, and uses the modified Mars model data as the cross-section model target data. By comparing the cross-section model target data and the cross-section model data, the model modification data is identified, and according to the modification data, the corresponding model object data in the S3D model is reversely located and automatically updated.

[0072] In this embodiment, the data of the connection nodes of the plate frame, cabin and longitudinal bone contained in a certain cross-section position of the S3D model are converted into the input data of the Mars model; the S3D model is automatically updated according to the modified data of the strake, frame and plate seam of the Mars model after calculation and optimization. The process of repeated modeling and modification is omitted, and the modeling operation efficiency of designers is improved.

[0073] In one embodiment, Figure 5 As shown, the pre-processing module 320 includes:

[0074] The parsing unit 321 is used to parse the original data of the cross-section model to obtain strake data, frame data, node data, cabin data and bracket data;

[0075] The conversion unit 322 is used to convert the data formats of the strake data, the frame data, the node data, the cabin data and the bracket data respectively, so as to obtain the cross-section model data in the file data format corresponding to the Mars model.

[0076] The specific preprocessing process is as follows: sort the nodes of each plate frame according to the order of plate frame arrangement and define the node serial number. The data of the column plates and frames on the frame are sorted with the starting node of the frame as the reference point and the extension direction of the frame as the condition. According to the composition of the cabin boundary frame, select the characteristic nodes of the boundary frame, record the serial number of the node, and combine the node serial numbers in the counterclockwise direction of the cabin boundary as the node composition of the cabin. The column plates, frames and cabin data are directly mapped according to the rules in Mars. The longitudinal bone connection node data mainly includes two parts: the connection form of the longitudinal bone end and the distance from the fatigue hot spot to the nearest end of the span. The connection form of the longitudinal end is converted by combination and matching. The type and arrangement of the bracket connected to the longitudinal at the strong frame are combined and matched one by one with the longitudinal connection form included in Mars. The distance from the fatigue hotspot to the nearest end of the span is calculated by creating a translation surface. According to the requirements of the CSR specification, a plane with a distance from the longitudinal wing plate surface of 1 / 2 the total height of the longitudinal is established to obtain the length of the intersection line with the bracket, and the value is calculated by combining the end connection form.

[0077] In one embodiment, Figure 5 As shown, the adjustment module 340 includes:

[0078] A determination unit 341 is used to compare the cross-section model data with the cross-section model target data to determine the strake thickness data, frame size data, plate seam displacement data and frame displacement data that have differences;

[0079] The updating unit 342 is used to update the corresponding data in the S3D model according to the different strake thickness data, frame size data, plate seam displacement data and frame displacement data.

[0080] Specifically, the original file corresponding to the cross-section model data and the modified file corresponding to the cross-section model target data are read row by row, and all data contained in the data headers "STRAKES", "STIFF LOC" and "STIFF SCANT" are recorded. The determination unit 341 compares the data row by row, filters out the modified data in the strake thickness data, the frame size data and the plate seam displacement data, and records the modified strake position, thickness and width data, frame position, size and type data.

[0081] The updating unit 342 makes a one-to-one correspondence between the S3D model and the Mars model, and locates the S3D model object that needs to be updated according to the position information in the strake and frame modification data. The strake thickness and frame size are updated by directly modifying the object attribute value of the S3D model. A new position plane is established in the S3D model according to the position information in the frame modification data, and a new frame is created at the position plane using the Sketch2D drawing method, and then the unnecessary frame is deleted, so that the frame position can be updated, and the S3D model can be adjusted according to the above method.

[0082] In this embodiment, the preprocessing module preprocesses the original data of the cross-section model corresponding to the S3D model to obtain cross-section model data that meets the input specifications of the Mars model. The adjustment module updates the S3D model through the comparison results of the cross-section model target data and the cross-section model data, which greatly shortens the modeling and model modification time and significantly improves the efficiency of ship modeling. In addition, data conversion is based on a single data source, eliminating human modeling errors and significantly improving the quality of ship design.
