Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to an attribute determination method, device, equipment and storage medium. Background Art

[0002] With the rapid development of finite element numerical analysis theory and computer technology, finite element models have been used throughout the aircraft design and airworthiness certification process. In order to meet the needs of rapid iteration design, it is often necessary to quickly set the finite element model properties for the entire wing box section of the aircraft.

[0003] At present, there are two common methods for determining and setting model attributes. One method relies on manpower to create unit attributes one by one. However, the structural parameters of different regions between structural parts are different. Using this method to create or update the finite element unit attributes of composite structures is very cumbersome and requires a lot of manpower and time. It is also easy to input errors in the ply angle or sequence, affecting the accuracy of the finite element calculation results. The other method represents the geometric characteristics of the wing box section structure in a parametric form in the form of a data form, so that the design input of the finite element model is transformed from a specific numerical model to a parameter form. However, the finite element model established by this method is not accurate, and the number of form parameters is huge, and the relationship between the parameters is complex, which leads to the problem that the finite element model attributes are extremely prone to errors and difficult to check.

[0041] Embodiment 1

[0042] Figure 1It is a flow chart of a property determination method provided in the first embodiment of the present invention. This embodiment can be applied to the situation of quickly and batch-determining the unit properties of the entire wing box section when constructing a finite element model. The method can be executed by a property determination device, which can be implemented in the form of hardware and / or software.

[0043] like Figure 1 As shown, the method includes:

[0044] S101, obtaining a target unit parameter table of a target structure in the entire wing box segment.

[0045] In this embodiment, the wing box section as a whole can be understood as the wing box of the aircraft wing, which is the main load-bearing structure of the wing. The wing box section as a whole is composed of a front beam, a rear beam, an internal wing rib frame, and upper and lower wall panels, and the wall panels are composed of long stringers and skins. Figure 2 FIG. 1 is an example diagram showing the entire wing box section involved in a method for determining an attribute provided in Embodiment 1 of the present invention. Figure 2 As shown, the wing box section as a whole includes at least: skin, long stringer, beam and rib. The target structure can be understood as a single structure for property determination, which is any structure among skin, long stringer, beam and rib. The target unit parameter table can be understood as a data storage table storing unit parameters of the target structure.

[0046] Specifically, for different target structures, a target unit parameter table of the target structure in the entire wing box section is obtained. The target unit parameter table stores unit parameters of each unit of the target structure. It can be understood that the target unit parameter table of the target structure is a table manually constructed by the operator.

[0047] Exemplarily, when the target structure is a skin, the target unit parameter table stores unit parameters of the skin structure, including skin offset (distance from the mid-surface to the outer surface), single-layer material, number of plies, and a ply parameter library, wherein the ply parameter library can be understood as a storage table for determining the ply angle, ply sequence, and ply thickness corresponding to the number of plies. Figure 3 FIG. 1 is an example diagram showing a target unit parameter table involved in a property determination method provided in Embodiment 1 of the present invention. Figure 3 As shown, taking the number of plies as an example, the target unit parameter table stores the number of plies of the corresponding position unit. Figure 3 The number of plies in the target unit parameter table includes 20 layers, 18 layers, 16 layers, 14 layers, 12 layers, and 10 layers. When the target structure is a long stringer, the unit parameters of the long stringer structure are stored in the target unit parameter table, including the long stringer area, the long stringer offset (the distance between the long stringer centroid and the outer surface) and the moment of inertia of the long stringer around the horizontal axis. It can be understood that the content stored in the target unit parameter table is determined according to actual needs, and this embodiment does not limit this.

[0048] In this embodiment, the use of a ply parameter library effectively reduces the number of parameters of the composite material structure, and the ply thickness, ply angle and ply sequence of the structure can be quickly determined by comparing the ply number to the ply library.

[0049] S102, constructing an initial unit number table of the target structure, and rearranging the initial unit number table according to the unit positions of the target structure to form a target unit number table corresponding to the positions of the target unit parameter table.

[0050] In this embodiment, the initial unit number table can be understood as a table arranged according to the automatically generated unit numbers, and each unit in the initial unit number table cannot be associated with each unit of the actual target structure by position. The target unit number table can be understood as a unit number table generated by rearranging the initial unit number table according to the unit positions of the target structure, corresponding to the position of the target structure and also corresponding to the position of the target unit number table.

[0051] Specifically, the initial unit number table of the target structure is constructed by arranging the numbers automatically assigned by the system, and each unit number represents a unit of the target structure. According to the center coordinates of the units of the target structure in the reference coordinate system, the initial unit number table is rearranged according to the unit positions of the target structure, and the units in the same row of the target structure are first determined, and then each row is sorted by column according to the determined unit coordinates of each row to form a target unit number table with regular row and column positions. At this time, the target unit number table formed corresponds to the position of the target structure, and the unit number table also corresponds to the position of the target unit number table.

[0052] For example, Figure 4 is an example diagram of the regular arrangement of an initial unit number table involved in a method for determining an attribute provided in the first embodiment of the present invention; Figure 5 FIG. 1 is an example diagram of the rule arrangement of the target unit number table involved in the attribute determination method provided in the first embodiment of the present invention. Figure 4 The initial unit number table originally arranged in the order of 1-33 is rearranged to form the following Figure 5 The non-sequential target unit number table shown in Figure 5 In the above example, the plane unit positions of each target structure in the whole wing box section can be one-to-one corresponding to the rearranged target unit number table. It can be understood that Figure 4 and Figure 5 This is a simplified version of the thumbnail diagram. The overall target structure of the wing box section is not just Figure 4 and Figure 5 Number of units shown.

[0053] S103, determining the unit attributes of the entire wing box segment according to the position correspondence between the target unit parameter table and the target unit number table.

[0054] In this embodiment, the unit attributes of the wing box section as a whole can be understood as the unit attributes of the skin, long stringers, beams and ribs, and each structure has its own corresponding unit attributes, wherein the unit attributes can be understood as the unit parameters of the target structure stored in the target unit parameter table.

[0055] Specifically, each structure in the entire wing box section can be used as a target structure to determine the corresponding unit attributes. According to the position correspondence between the target unit parameter table and the target unit number table, the unit parameters corresponding to each unit number in the target unit number table in the target unit parameter table are determined in batches, and the unit parameters are determined as the unit attributes of the unit, and the unit attributes of the target structure are further obtained. According to the unit attributes of each structure in the entire wing box section, the unit attributes of the entire wing box section are determined.

[0056] For example, Figure 6 1 is an example diagram of the correspondence between the target unit parameter table and the target unit number table involved in the attribute determination method provided in the first embodiment of the present invention. Figure 6 As shown, the target unit parameter table and the target unit number table correspond one to one in position, so the target unit parameter table can be directly located according to the position of the unit in the target unit number table, and the attribute parameters of the unit can be directly determined. For example, the number of plies corresponding to the unit number 22 can be determined to be 20, and the number of plies corresponding to the unit number 11 can be determined to be 10 according to the position correspondence between the target unit number table and the target unit parameter table.

[0057] In this embodiment, the target unit parameter table of the target structure in the wing box segment as a whole is obtained; the initial unit number table of the target structure is constructed, and the initial unit number table is rearranged according to the unit position of the target structure to form a target unit number table corresponding to the position of the target unit parameter table; according to the position correspondence between the target unit parameter table and the target unit number table, the unit attributes of the wing box segment as a whole are determined. The above technical scheme can quickly determine the unit attributes in batches, ensure the accuracy of the unit attribute determination, improve the accuracy of the unit attribute determination, greatly improve the work efficiency, reduce the workload, and can be applied to a variety of attribute determination scenarios, ensuring the reusability of the method.

[0058] As a first optional embodiment of the embodiment, based on the above embodiment, this first optional embodiment further optimizes and adds: setting a finite element model according to the unit properties of the entire airfoil box segment.

[0059] In this embodiment, the finite element model can be understood as a model established when the finite element analysis method is used in the aircraft structure design process. With the rapid development of finite element numerical analysis theory and computer technology, more and more complex engineering problems and large-scale structural analysis problems are solved using the finite element method. In aircraft structure design, structural internal force analysis, structural deformation analysis and thermal stress analysis are carried out based on the finite element model to complete the airframe structure strength assessment, fatigue load spectrum compilation and test load compilation. The finite element model has been used throughout the aircraft's conceptual design, preliminary design, detailed design and airworthiness certification process. It is an important carrier for the docking of structure, load and strength professional work, and is of great significance in airframe structure design. The aircraft wing box structure needs to meet the requirements of multi-disciplinary design such as statics, fatigue, assembly, process, flutter, etc. at the same time. Its design often requires dozens of rounds of multi-disciplinary collaborative iterations, and the finite element model is the basis of static, fatigue, flutter and other disciplines. The unit properties need to be updated in each round of iteration. Whether the finite element model can be quickly updated in each round of design iteration is one of the keys to speeding up the development process of the wing box structure.

[0060] Specifically, in order to meet the needs of rapid iterative design, during the construction of the finite element model, the finite element model properties are quickly set according to the determined unit properties of the entire wing box section, thereby achieving rapid update settings of the finite element model properties and supporting strength evaluation.

[0061] Embodiment 2

[0062] Figure 7 It is a flow chart of a property determination method provided in the second embodiment of the present invention. This embodiment is a further optimization of any of the above embodiments and can be applied to the situation of batch-fast determination of the unit properties of the entire wing box section when constructing a finite element model. The method can be executed by a property determination device, which can be implemented in the form of hardware and / or software.

[0063] like Figure 7 As shown, the method includes:

[0064] S201, obtaining a target unit parameter table of a target structure in the entire wing box segment.

[0065] S202, constructing an initial unit number table of the target structure, where the initial unit number table is an initial table arranged by number.

[0066] In this embodiment, the numbers are arranged in the order automatically assigned by the system to construct the following Figure 4 As shown, a table of initial unit numbers relative to the target structure.

[0067] S203, rearrange the initial unit number table according to the center coordinates of the units in the target structure to form an intermediate table arranged in rows.

[0068] In this embodiment, the intermediate table can be understood as a table in which the row positions are correct but the column positions are not necessarily correct. The row coordinates of the cells stored in each row of the intermediate table are arranged in ascending order.

[0069] Specifically, the initial cell number table determines the cells in the same row according to the center coordinates of the cells in the target structure, the cells in the same row are grouped together, each row is rearranged, and the order of the cells in the same row from small to large is determined to form an intermediate table arranged in rows.

[0070] For example, Figure 8 is an example diagram of the arrangement of the same-row cells involved in the attribute determination method provided in the second embodiment of the present invention. Figure 8 As shown, rearrange according to the central coordinates of the units in the target structure to determine Figure 8 The 28 cells in the same row shown in the second row are arranged in ascending order according to the row coordinates, and based on this, an intermediate table is formed in which the row coordinates of each row are arranged in ascending order (for example, A1-A28).

[0071] S204, rearrange the intermediate table according to the column coordinates of the first cell in each row to form a target cell number table arranged according to the cell positions of the target structure and corresponding to the positions of the target cell parameter table.

[0072] In this embodiment, the intermediate table is a table with correct row positions but not necessarily correct column positions. Therefore, the intermediate table is rearranged to form a target unit number table with correct row and column positions, arranged according to the unit positions of the target structure, and corresponding to the positions of the target unit parameter table.

[0073] Specifically, the intermediate table is rearranged in units of rows according to the size of the column coordinates of the first cell in each row of the intermediate table. The order can be from large to small or from small to large. The ordering rule is determined according to the reference coordinate system, and this embodiment does not limit this. After the intermediate table is rearranged according to the size of the column coordinates, a target cell number table is formed with correct row and column positions, arranged according to the cell positions of the target structure, and corresponding to the position of the target cell parameter table.

[0074] For example, Fig. 9 is an example diagram of arranging cells according to column coordinates in a method for determining an attribute provided in the second embodiment of the present invention. Fig. 9 As shown, there are nine rows of cells, A, B, C, D, E, F, G, H, and I. The coordinates of the first cells A1, B1, C1, D1, E1, F1, G1, H1, and I1 of these nine rows are compared and arranged, and the order of column coordinates from small to large or from large to small is formed as follows Fig. 9The example diagram shown is an example of cell arrangement by column coordinates, and a target cell number table is formed based on this.

[0075] S205 , according to the position correspondence between the target unit parameter table and the target unit number table, associate the unit number and unit parameter of each unit in the target structure to determine the unit attribute of the target structure.

[0076] In this embodiment, the unit attributes of the target structure can be understood as unit parameters of all units of the target structure.

[0077] Specifically, the target unit number table is arranged according to the unit position of the target structure. The target unit number table corresponding to the position of the target unit parameter table associates the unit number and unit parameter of each unit in the target structure according to the position correspondence between the target unit parameter table and the target unit number table, and directly determines the unit attributes of the target structure.

[0078] For example, Fig.10 This is an example diagram of a ply parameter library involved in a property determination method provided in the second embodiment of the present invention. When the target structure is a skin, according to the position correspondence between the target unit parameter table and the target unit number table, for a certain unit, the corresponding property parameters such as the number of plies, single layer material, and skin offset stored in the target unit parameter table are determined according to its unit number, and then according to the number of plies, the ply thickness, ply angle, and ply sequence are determined by comparing the ply parameter library. For example, if the number of plies of the unit is 20, according to Fig.10 The ply parameter library shown determines that the ply angle of each layer corresponding to the unit is [45° / -45° / 0° / 90° / 0° / 45° / -45° / 0° / 90° / 45° / -45° / 90° / 0° / -45° / 45° / 0° / 90° / 0° / -45° / 45°].

[0079] S206. Determine the unit attributes of the entire wing box segment according to the unit attributes of the target structure.

[0080] In this embodiment, the target structure can be any structure among the skin, long stringers, beams and ribs. The wing box section as a whole includes the above-mentioned target structures. According to the unit properties of each target structure, they are combined together to determine the unit properties of the wing box section as a whole.

[0081] In this embodiment, by obtaining the target unit parameter table of the target structure in the whole wing box segment; constructing the initial unit number table of the target structure, the initial unit number table is an initial table arranged by number; rearranging the initial unit number table according to the center coordinates of the units in the target structure to form an intermediate table arranged by rows; rearranging the intermediate table according to the column coordinates of the first unit in each row to form a target unit number table arranged according to the unit position of the target structure and corresponding to the position of the target unit parameter table; according to the position correspondence between the target unit parameter table and the target unit number table, the unit number and unit parameter of each unit in the target structure are associated to determine the unit attribute of the target structure; according to the unit attribute of the target structure, the unit attribute of the whole wing box segment is determined. In the above technical scheme, the determination of unit attributes can be realized quickly in batches, the accuracy of unit attribute determination is guaranteed, the accuracy of unit attribute determination is improved, the work efficiency is greatly improved, the workload is reduced, and it can be applied to a variety of attribute determination scenarios to ensure the reusability of the method.

[0082] As a first optional embodiment of the embodiment, based on the above embodiment, this first optional embodiment further optimizes and adds the step of rearranging the initial unit number table according to the center coordinates of the units in the target structure to form an intermediate table arranged in rows. Fig.11 is a flow chart of another attribute determination method provided by Embodiment 2 of the present invention. Fig.11 As shown, including:

[0083] a1) Construct an initial unit set, and store each unit in the initial unit number table into the initial unit set.

[0084] In this embodiment, the initial unit set can be understood as a set storing all unit numbers in the initial unit number table, which is used to assist in the rearrangement of the initial unit number table.

[0085] Specifically, an empty set is constructed as the initial unit set, and each unit in the initial unit number table is stored in the initial unit set.

[0086] b1) Take the first cell in the initial cell set as the current target cell, determine the cell in the same row as the current target cell in the initial cell number table according to the center coordinates of each cell in the target structure, and store the cell in the same row as the current target cell in the current row set until the traversal termination condition of the current row is met.

[0087] In this embodiment, the current target cell can be understood as an initial cell used to determine cells in the same row, and can be understood as a cell used as a calibration reference. The current row set can be understood as a set of cells that store the current target cell and the same row as the current target cell. The traversal termination condition of the current row can be understood as a condition for ending the search for cells in the same row in the initial cell number table, for example, the cells in the same row as the current target cell that have not been found in the initial cell number table no longer exist.

[0088] Specifically, the first unit in the initial unit set is taken as the current target unit, and the center coordinates of each unit are determined in combination with the preset reference coordinate system. According to the center coordinates of the current target unit and the center coordinates of other units, the unit in the same row as the current target unit in the target structure is determined. The row set of the current row is constructed, and the current target unit and the units in the same row as the current target unit are stored in the current row set until there are no unfinded units in the same row as the current target unit in the initial unit number table, that is, the units in the same row as the current target unit in the initial unit number table have been completely found.

[0089] c1) Clear the cells of the current row set stored in the initial cell set, and return to re-execute the step of determining the current target cell until the initial cell set is empty.

[0090] In this embodiment, when the traversal termination condition of the current row is satisfied, the current row set has stored the cell numbers of the current target cell and all cells in the same row as the current target cell in the initial cell number table, and the cell numbers of the current row set are cleared in the initial cell set. At this time, the cell numbers stored in the initial cell set are the numbers of cells that have not been searched in the same row. Return to re-execute step b1), re-take the current first cell in the initial cell set as the current target cell, and search in the same row as the current target cell, until the initial cell set becomes an empty set after clearing the current row set again and again.

[0091] d1) Forming an intermediate table arranged in rows according to each current row set.

[0092] In this embodiment, according to steps b1) and c1), an intermediate table in which row coordinates are arranged in order is determined in units of rows.

[0093] Furthermore, Fig.12 is a flow chart of another attribute determination method provided by the second embodiment of the present invention. Fig.12 As shown, the cells in the same row as the current target cell in the initial cell number table are determined according to the center coordinates of each cell in the target structure, and the cells in the same row as the current target cell are stored in the current row set until the traversal termination condition of the current row is met, including:

[0094] b11) Determine the cell adjacent to the current target cell in the initial cell number table as the reference cell.

[0095] In this embodiment, the reference unit can be understood as a unit used to determine whether it is in the same row as the current target unit one by one. The reference unit is a unit that is adjacent to the current target unit in the initial unit number table.

[0096] Specifically, the unit that is adjacent to the current target unit in the initial unit numbering table and has two common nodes is determined as a reference unit for determining whether it is in the same line as the current target unit one by one. The current target unit has at most four reference units in the initial unit numbering table, which are respectively at the up, down, left and right positions. There are at least two reference units, which can be any two of the up, down, left and right positions.

[0097] For example, Fig.13 FIG. 1 is an example diagram showing a reference unit involved in another attribute determination method provided in Embodiment 2 of the present invention. Fig.13 As shown, A is the current target unit, and B1, B2, B3, and B4, which are adjacent to the current target unit A and have two common nodes, are determined as reference units.

[0098] b12) judging whether the reference unit is a unit in the same line as the current target unit according to the center coordinates of the current target unit and the reference unit in the preset coordinate system.

[0099] In this embodiment, the preset coordinate system can be understood as a reference coordinate system determined based on the overall structure of the airfoil box segment, for example, the X-axis of the reference coordinate system points in the span direction of the airfoil box segment, and the Y-axis points in the chord direction of the airfoil box segment.

[0100] Specifically, the center coordinates of the current target unit and the reference unit in the preset coordinate system are calculated respectively, and the cosine value of the angle between the center coordinate position of the current target unit and the center coordinate position of each reference unit and the vector in the X-axis direction of the reference coordinate system is calculated respectively.
