Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items. In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Fig. 1 is a block diagram of a method for modifying grid cells according to an embodiment of the present invention. The key of the batch modification method is that the mapping relation between the grid cells of the plate shell model and the cells of the table is utilized, so that the model data information of the grid cells can be filled into the cells corresponding to the table.
Therefore, the information of the grid cells can be converted into the form of a table to be expressed, and the batch modification of the grid cells is realized by utilizing the characteristic that the table can execute batch modification operation. The specifically used form may be implemented in any software, such as an Excel form, which is widely used.
As shown in fig. 1, the batch modification method of the grid cell model data may include the steps of:
step 110: and determining the mapping relation between the grid cells and the cells of the table.
The grid cell numbers and characteristic numbers in the grid model are all distributed according to a specific mathematical rule. A typical distribution may be a linear function, for example, an initial cell number of 100, with 1 per cell increment.
It will be appreciated that such numbering arrangements are in fact consistent with the arrangement of cells in the table. For example, similar to the form manipulation function in Excel software. Therefore, grid cells of the three-dimensional grid model such as the plate-shell structure can be mapped into cells in the table, and a mapping relation between the grid cells and the table can be established.
In some embodiments, the step of determining the mapping relationship may include:
first, the three-dimensional model is cut along a set direction and flattened on a plane in which the table is located. The direction of the setting can be specifically selected according to the actual situation. In particular, it consists of a series of consecutive grid cells in a straight line. The three-dimensional model can be expanded along this direction, tiled onto Excel tables.
Then, the mapping relation between each grid cell in the three-dimensional model and the cells of the table is determined by means of automatic expansion or manual expansion. The grid cells after spreading can be used for establishing a mapping relation with each cell in the table by selecting a proper reference standard.
Step 120: and recording various model data of the grid unit through a plurality of tables according to the mapping relation.
Wherein the mapping relationship indicates a correspondence relationship between each cell and the grid cell. Thus, each model data can be filled into a single table for recording. That is, each table is used to record one model data.
The model data refers to information about each grid cell, such as profile thickness, material or other relevant attribute data, etc. The final goal of the batch modification operation is to modify the information of the individual grid cells.
Step 130: and carrying out corresponding batch modification operation on the table according to the received modification instruction so as to update the data information of the table.
Through the above steps, the information of each grid cell in the grid model is converted into a plurality of tables. Thus, modification of the grid model may be achieved through batch modification operations on the tables.
The modification instruction may specifically be any type of instruction information. Which is entered by the designer according to the modification requirements. In the actual operation process, the related office software such as Excel can complete batch modification operation of the table very simply and quickly.
Step 140: and generating a model modification file corresponding to the data information of the updated table.
After the batch modification operation, the data information of the table is updated. And recording the updated data information of the tables in a set format by means of computer programming and the like to form a final model modification file. The specific adopted format can be set by a technician according to the actual situation, and only the standard of three-dimensional software import needs to be met.
Step 150: importing the model modification file.
After the model modification file meeting the standard is generated, the model modification file can be imported into computer three-dimensional software, and a grid model corresponding to the modified grid unit is generated according to the model modification file so as to realize batch modification operation.
In the process of generating the model modification file, the key is to acquire the required model data of the grid cells in a form search mode so as to support automatic modification of the grid model by three-dimensional software.
Fig. 2 is a flowchart of obtaining model data of a grid cell to generate a model modification file according to an embodiment of the present invention. As shown in fig. 2, the step of generating the model modification file may include:
step 141: and acquiring the number information of the target grid cell related to the modification instruction.
The user entered modification instructions will point to the grid cells that need to be modified. The grid cells that require bulk modification are referred to herein as "target grid cells".
Step 142: and determining the cell positions of the target grid cells in a coding table according to the number information.
As disclosed in the above embodiments, the model data of the grid cell is recorded by a plurality of tables and converted into the form of table data. The same cell locations in each table represent the same target grid cells. Thus, determining the cell location of the target grid cell in one of the tables may continue to obtain additional model data.
Step 143: and acquiring node information corresponding to the grid unit in a node table.
Nodes are the basic components of the grid cell. The node table is node information for storing nodes constituting the grid cell. Which may take any suitable type of table or data storage structure. That is, it is only necessary to be able to record the association between each grid cell and the nodes that make up that grid cell.
In particular, different types of grid cells are composed of different numbers of nodes. Node information of these different types of grid cells can be recorded correspondingly in the node table. For example, when the grid cell is a quadrangular grid cell, four node information may be acquired from the node table. And when the grid unit is a triangular grid unit, three node information is acquired from the node table.
Step 144: and searching the section thickness information and the characteristic information of the target grid unit in the thickness table and the characteristic table respectively according to the cell positions.
After determining the cell positions of the target grid cells, other model data (such as profile thickness information and characteristic information) of the target grid cells can be obtained from other thickness tables and characteristic tables according to the cell positions.
Step 145: a corresponding model modification file is generated.
Based on the obtained model data of the target grid unit, specific data information can be generated into a model modification file meeting the standard in a set format through a computer programming mode and the like.
The following takes a fuselage beam frame model of an airplane as an example, and describes in detail the specific implementation process of the grid cell batch modification method provided by the embodiment of the invention:
as shown in fig. 3, the fuselage beam model of the aircraft is presented as a barrel-shaped slab-shell structure. The frame can be decomposed into a plurality of sections along the circumferential direction of the frame. Each segment is a grid cell (grid cells have independent numbering information, marked on the grid cells) and may correspond to a column in a table. And the grid cells forming the frame of the fuselage are equivalent to rows in a table.
Therefore, the frame beam model can be cut along the frame direction K, the grid cells are tiled and unfolded on the table, and then the mapping relation between each grid cell and the cells in the table can be determined through a proper unfolding standard.
Specifically, the grid cell that cuts the cut surface L of the body beam model may be used as a reference grid, and the coordinate value of the first reference grid located on the left side of the cut surface may be initialized to (0, 0) and set as the origin of the planar coordinate system.
Then, the coordinate values of the remaining reference grids are initialized to (0, k) in sequence. Where k represents the kth reference grid after the first reference grid, and the setting of the plane coordinate system is completed.
After initializing the reference grid, the reference grid may be used as a search start point, and one grid cell may be used as a step length to search for an adjacent grid cell.
In the searching process, judging whether the adjacent grid unit is a reference grid or not. If so, the search cycle is jumped out. If not, calculating coordinate values of adjacent grid cells according to the relative position relation.
It should be noted that different types of grid cells have different coordinate value calculation manners. For example, the number of the cells to be processed,
as shown in fig. 4a, when the grid cell is a quadrangular grid cell, coordinate values of four grid cells connected to four sides thereof may be sequentially calculated.
When the coordinate value of the known marking grid cell is (m, n), the coordinate value of the first grid cell to be marked connected with the top edge 1 of the marking grid cell is (m-1, n), the coordinate value of the second grid cell to be marked connected with the right side edge 2 of the marking grid cell is (m, n+1), the coordinate value of the third grid cell to be marked connected with the bottom edge 3 of the marking grid cell is (m+1, n), and the coordinate value of the fourth grid cell to be marked connected with the left side edge 4 of the marking grid cell is (m, n-1).
As shown in fig. 4b, when the grid cell is a triangle grid cell, coordinate values of three grid cells connected to three sides thereof may be sequentially calculated.
Similarly, assuming that the coordinate value of the known marking grid cell is (m, n), it may be determined that the coordinate value of the first grid cell to be marked, which is connected to the upper hypotenuse 1 of the triangular marking grid cell, is (m-1, n), the coordinate value of the second grid cell to be marked, which is connected to the lower hypotenuse 2 of the triangular marking grid cell, is (m+1, n), and the coordinate value of the third grid cell to be marked, which is connected to the base 3 of the triangular marking grid cell, is (m, n-1).
Finally, after all the coordinate values of the grid cells are calculated, judging whether all the coordinate values of the grid cells are larger than or equal to zero. If yes, the mapping relation can be directly output. If not, the adjustment is needed, and the absolute value of the minimum value of the coordinate values is added to ensure that all the coordinate values are positive numbers, and the coordinate values can correspond to the number of rows and columns of the table.
Through the automatic unfolding mode, the corresponding cell of each grid cell in the table can be obtained. The numbering information of the grid cells may be filled into the corresponding cells and different types of cells marked with different identifications to form a numbering table.
As shown in fig. 5a, in the numbering table, the square grid cells are directly filled with the numbering information in the cells, the triangle grid cells add the base color as different identifications in the cells of the numbering table, and the empty grid cells are represented by blank spaces.
Further, other model information is recorded by other different tables. As shown in fig. 5b, the cross-sectional thickness information of the corresponding grid cell is recorded in each cell. As shown in fig. 5c, characteristic information of the corresponding grid cell is recorded in each cell.
Thus, the batch modification operation for the grid cells may be embodied as an update to the data information of the cells in the plurality of tables. In the actual operation process, the data updating condition of the cells in the table can be obtained by the following modes:
11 Obtaining the number information of the target grid cells and determining the corresponding cell positions.
12 Node information of the target grid cell is acquired. Specifically, node information of the grid cell can be simply recorded through a table as shown in fig. 5d, and corresponding node information is obtained after the number of the target grid cell is determined.
13 In the thickness table, the section thickness information recorded in the cells at the same position is read.
14 In the characteristic table, characteristic information recorded in the cells at the same position is read.
Repeating steps 11) to 14) until all grid cells are traversed to obtain the information required by the complete grid model.
Finally, the complete mesh model information can be automatically generated into a model modification file which meets the three-dimensional software format standard and can be read by the model modification file in a computer programming manner as shown in fig. 5 e. After the model modification file is imported, a batch modified model can be generated by three-dimensional software, and batch modification operation on grid cells is realized.
In summary, according to the batch modification method for the grid cells provided by the embodiment of the invention, after the information of the grid cells is converted into the representation of the plurality of tables, the batch modification operation of the grid cells is realized by utilizing the characteristic that the tables can be operated in batches, so that the working efficiency of designers can be effectively improved.
