Description

Technical Field

[0001] The present application belongs to the technical field of aircraft quality characteristic data processing, and in particular, relates to a method and device for batch supplementing missing sub-levels of an aircraft quality characteristic data set. Background Art

[0002] During the overall aircraft design process, the aircraft's mass characteristic data set often results in missing or incorrect quality characteristic data extraction due to incorrect attribute settings, inconsistent digital model formats, etc., and the sub-level quality characteristic data often does not match the top-level quality characteristic data. In the process of mass distribution, the sum of the underlying data is not equal to the top-level data, and the quality distribution analysis cannot be carried out. In addition, since all data except the missing data are accurate data extracted from the digital model, the missing data cannot be spread to other parts, causing the data of other parts to change.

[0003] Therefore, a pre-processing method is needed that can not only ensure that the calculation results of the upper and lower levels of the quality characteristic data set match, but also ensure that all sub-levels are consistent with the original data after pre-processing. Automatically supplementing missing sub-levels is a better way to solve this problem. Summary of the invention

[0014] The weight distance of the missing sub-level is obtained by multiplying the weight and the center of gravity of the assembly level in a single single-level data group and the weight and the center of gravity of other assembly sub-levels except the missing sub-level. The center of gravity of the missing sub-level is obtained by dividing the weight distance by the weight of the missing sub-level.

[0015] The inertia and mass of the axis shifting are calculated based on the sum of the weight centers of all assembly sub-levels including the missing sub-level in a single single-level data group. The inertia and mass of the axis shifting are subtracted from the inertia and mass of the assembly level and the inertia and mass of the other assembly sub-levels except the missing sub-level, and the difference is taken as the inertia and mass of the missing sub-level.

[0037] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0038] The present application provides a method and system for batch supplementing missing sub-levels of an aircraft quality characteristic data set in order to solve the problem that the quality characteristic data set is missing some sub-levels due to various reasons and quality distribution analysis cannot be performed during the pre-processing of the quality characteristic data set.

[0039] like Figure 1 As shown, the missing sub-level batch supplementation method of the aircraft quality characteristic data set of the present application includes:

[0040] S10, obtaining an aircraft quality characteristic data set, generating an aircraft quality characteristic data table according to the aircraft quality characteristic data set, and splitting the aircraft quality characteristic data into a plurality of single-level data groups according to the assembly level and the unit level.

[0041] Table 1 is a partial table of aircraft mass characteristic data examples according to an embodiment of the present application. The aircraft mass characteristic data table includes weight, center of gravity coordinates, moment of inertia, product of inertia, and the like.

[0042] Table 1 Aircraft quality characteristics data table

[0043]

[0044] For example, the aircraft quality characteristic data in Table 1 can be divided into 7 single-level data groups, namely, assembly level 1, assembly level 1.1, assembly level 1.2, assembly level 1.2.1, assembly level 1.2.2, assembly level 1.2.3, and assembly level 1.3. Each single-level data group contains the quality characteristic data of the assembly level and its sub-levels. The above 7 single-level data groups are arranged from top to bottom according to the hierarchical relationship.

[0045] S20, determining the missing sub-level for which aircraft quality characteristic data needs to be supplemented and the single-branch single-level data group to which it belongs, and calculating the data of the missing sub-level according to the single-branch single-level data group to which the missing sub-level belongs.

[0046] In the aircraft mass characteristic data, the sum of the weights at each level is equal to the weight of the previous level. For example, the sum of the weights of assembly levels 1.1 to 1.3 should be the mass of assembly level 1, the sum of the weights of assembly sub-levels 1.1.1 to 1.1.4 should be the mass of assembly level 1.1, and so on. If the sum of the weights of an assembly level and its next level or sub-level is not equal, it is determined that there is a missing sub-level in the assembly level. For example, when assembly sub-level 1.1.1 is missing, the sum of the weights of assembly sub-levels 1.1.2 to 1.1.4 is less than the weight of assembly level 1.1, thereby determining that there is a missing sub-level 1.1.1 in assembly level 1.1, and determining the single-unit single-level data group of the assembly level where the missing sub-level 1.1.1 is located.

[0047] In this application, the process of calculating the data of the missing sub-level according to the single-level data group where the missing sub-level is located includes:

[0048] S21, obtaining the weight of the missing sub-level according to the difference between the weight of the assembly level in the single-level data group and the weights of other assembly sub-levels except the missing sub-level;

[0049] For example, the weight of assembly level 1.1 is 1, and the sum of the weights of assembly sublevels 1.1.2 to 1.1.4 is 0.8, so the weight of the missing sublevel 1.1.1 can be calculated to be 1-0.8=0.2;

[0050] S22, obtain the weight distance of the missing sub-level according to the product of the weight and the center of gravity of the assembly level in the single single-level data group and the product of the weight and the center of gravity of other assembly sub-levels except the missing sub-level, and obtain the center of gravity of the missing sub-level according to the weight distance divided by the weight of the missing sub-level obtained in step S21.

[0051] For example, when calculating the centroid X of the missing child 1.1.1, the calculation formula is:

[0052] (1*22.023-0.3*22.041-0.25*22.041-0.25*22.036) / 0.2=22.957

[0053] The calculations for the center of gravity Y, Z, and X of the missing sub-level 1.1.1 are the same and will not be repeated here.

[0054] S23, calculating the inertia and mass of the axis shifting according to the sum of the weight centers of gravity of all assembly sub-levels including the missing sub-level in the single-stage data group, and subtracting the inertia and mass of the axis shifting from the inertia and mass of the assembly level and the inertia and mass of the other assembly sub-levels except the missing sub-level, and taking the difference as the inertia and mass of the missing sub-level.

[0055] In a preferred embodiment of the present application, when the difference between the weight of an assembly level and the weight of other assembly sub-levels except the missing sub-level is negative, the missing sub-level is marked as deducted weight.

[0056] Step S30, traverse all single-branch single-level data groups, repeat step S20, and fill in the missing sub-levels in all single-branch single-level data groups.

[0057] The method of the present application can supplement the missing sub-levels in the aircraft mass characteristic data set more quickly and accurately, so that the quality characteristic data of the upper and lower level data match each other, and can distinguish between the deducted weight with negative weight and the missing sub-level with positive weight, thereby avoiding the influence of negative weight on the mass distribution analysis.

[0059] The preprocessing module 101 is used to obtain an aircraft quality characteristic data set, generate an aircraft quality characteristic data table according to the aircraft quality characteristic data set, and split the aircraft quality characteristic data into a plurality of single-level data groups according to the assembly level and the unit level;

[0060] The data calculation module 102 is used to determine the missing sub-levels for which the aircraft quality characteristic data needs to be supplemented and the single-branch single-level data group to which they belong, and calculate the data of the missing sub-levels according to the single-branch single-level data group to which the missing sub-levels belong;

[0061] The traversal module 103 is used to traverse all the single-branch single-level data groups and repeat the previous step to fill the missing sub-levels in all the single-branch single-level data groups.

[0062] The other processes performed by the missing sub-level batch replenishment device of the present application can refer to the steps of the missing sub-level batch replenishment method, which will not be repeated here.
