Description

Technical Field

[0001] This application belongs to the field of strength calculation, and specifically relates to an interference detection method and apparatus for adjacent moving airfoils. Background Technology

[0002] Generally, for high aspect ratio aircraft, there are multiple moving surfaces on the trailing edge of the wing, and the structures of these moving surfaces are arranged relatively compactly. During flight, the deflection angles of these moving surfaces are not entirely the same. If interference occurs between adjacent moving surface structures due to coupled deformation, it will affect the overall functionality and pose a flight safety risk. Therefore, to ensure the overall functionality of the moving surface structures and flight safety, it is necessary to check the deformation between the moving surfaces during flight.

[0003] The wing structure undergoes significant deformation, with displacements reaching or exceeding 10% of the wing's half-span. Simultaneously, the moving wing surfaces also experience localized deformation under localized loads. When considering the combined effects of wing deformation, moving wing surface deformation, and the deflection angle of the moving wing surfaces, determining the gaps and interference between the moving wing surfaces becomes quite challenging. Generally, visually examining the deformation results one by one using general-purpose finite element software is insufficient to accurately determine the gaps or interference between adjacent moving wing surfaces, making it difficult to achieve ideal results.

The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0052] The first aspect of this application provides a method for interference checking between adjacent moving wing surfaces, such as... Figure 1 As shown, it mainly includes:

[0053] Step S1: Determine the coordinates of each point on the docking end face of two adjacent moving wing surfaces in the global coordinate system;

[0054] Step S2: Using one end face as the reference plane, determine the plane equation of the reference plane through three non-collinear coordinate points, and project each point of the other end face onto the reference plane.

[0055] Step S3: Determine the first direction vector and the first distance between each point after projection and each point before projection;

[0056] Step S4: Calculate the deformation displacement of each point on the two end faces under the specified working condition using the finite element model, so as to determine the new coordinates of each point under the working condition in the global coordinate system;

[0058] Step S6: Calculate the dot product of the first direction vector and the second direction vector of each point before and after deformation;

[0059] Step S7: When there is a point whose dot product is less than 0, the two end faces interfere under this working condition; otherwise, the two end faces do not interfere.

[0060] refer to Figure 2 Adjacent moving surfaces are defined as control surface #1 and control surface #2, respectively, and correspondingly, they have end face 1 and end face 2.

[0061] Step S1 is used to read the deflection coordinate system information of the two moving airfoils under given load conditions, and update the nodes of the finite element of the adjacent end faces of the two moving airfoils under each load condition.

[0062] In some alternative implementations, step S1 further includes:

[0063] Step S11: Obtain the deflection coordinate systems of the two moving wing surfaces respectively, and calculate the deflection matrix from the local coordinate system to the global coordinate system based on the unit vector of the global coordinate system and the unit vector of the local coordinate system.

[0064] Step S12: Calculate the coordinates of each point on the two end faces in the global coordinate system based on each deflection matrix.

[0065] In this embodiment, the deflection coordinate systems of the two moving wing surfaces are obtained respectively, based on the unit vector of the global coordinate system. unit vector in local coordinate system Calculate its deflection matrix T from the local coordinate system to the global coordinate system:

[0066] .

[0067] Next, based on the origin O of the deflection coordinate system and the deflection matrix T, the coordinates of each point on the two end faces in the global coordinate system are calculated, as shown below:

[0068] .

[0069] Step S2 is used to perform projection calculations.

[0070] In some alternative implementations, in step S2, the projected coordinates of each point... Calculated using the following formula:

[0071] ;

[0072] in, The coordinates before projection, Let ABCD be the normal vector of the reference plane, and let ABCD be the equation of the plane. The coefficient.

[0073] In this embodiment, three non-collinear points on end face 1 are first selected, such as... Figure 3 As shown, read the coordinate information A of the three points here. B C The equation of the end face plane is determined and defined as the positioning plane P1.

[0074] ;

[0075] .

[0076] Read the finite element nodes of end face 2 of the adjacent #2 moving wing surface, and use the selected nodes as projection points, assigning them the corresponding numbers. ,like Figure 4 As shown.

[0077] Each projection point According to the normal vector of plane 1 Projected onto end face plane 1, the corresponding projection point is obtained. Coordinates are Then, in step S3, the projected point is calculated. With projection point Distance between and the direction vectors between them .

[0078] Step S4 is followed by analysis of the end face deformation under various working conditions.

[0079] In step S4, after the finite element model calculation is completed, the deformation displacement is read. Update the coordinate values ​​of each node after deformation of the adjacent end faces of the two moving airfoils:

[0080] .

[0081] Step S5 is used to update the deformed second direction vector and the second distance.

[0082] In some alternative implementations, step S5 is further preceded by:

[0083] Step S50: Project each point on the deformed end face onto the reference plane, determine the coordinate points after projection, and use the sign test method of vector cross product to determine whether the coordinate points after projection fall into each finite element mesh on the reference plane. Discard the coordinate points that do not fall into the finite element mesh.

[0084] In this embodiment, the finite element nodes of the end face 2 of the deformed #2 moving wing surface are... The points are projected onto end face 1 of the deformed #1 moving wing surface, and the projected points are then... The process iterates through each finite element mesh (quadrilateral element, triangular element) within plane 1 of the end rib of the #1 moving wing surface, determining whether it falls within a certain mesh. Figure 5 As shown.

[0085] The judgment method uses the sign test of the cross product of vectors, that is, the projection points... Each vector is cross-multiplied with the direction vector of each node in the finite element mesh in a clockwise direction, and then the resulting vectors are... With plane normal vector Calculate the dot product. If all the dot products have the same sign, it means that the point falls within the finite element mesh, and vice versa.

[0086] Understandably, if the node falls within the finite element mesh, it is necessary to calculate whether the two interfere. If it does not fall within the finite element mesh, it means that the node on end face 2 will not touch end face 1 during its movement and is not a node of the mating surface (the two wing surfaces are different sizes).

[0087] Then, in step S5, for the points of the finite element nodes of end face 2 within the range of end face 1, calculate the points projected after deformation. With projection point The second direction vector between With the second distance .

[0088] Then, in step S6, the deformation of each point before and after deformation is calculated. and dot product Record and update the second distance between end face 1 of rudder surface #1 and end face 2 of rudder surface #2.

[0089] Finally, in step S7, the dot product can be used as a basis. Determine whether interference occurs between the two wing surfaces.

[0090] In some alternative implementations, step S7 further includes:

[0091] If the dot product of all points is greater than 0, then the minimum value in the second distance is selected as the minimum distance between the two end faces.

[0092] When there are points where the dot product is less than 0, the maximum value in the second distance is selected as the interference amount between the two end faces.

[0093] In this embodiment, if all dot products are greater than 0, that is... This indicates that end face 1 of rudder surface #1 and end face 2 of rudder surface #2 are not interlocked. Therefore, calculate the minimum distance between the two end faces. ;

[0094] .

[0095] If there exists a dot product between two points that is less than 0, that is... This indicates that end face 1 of rudder surface #1 and end face 2 of rudder surface #2 are interlocked, causing interference. The interference amount needs to be calculated. ;

[0096] .

[0097] Record the interference at both end faces under various load conditions. or minimum distance As shown in Table 1, interference occurs between the two end faces under operating condition 105, but no interference occurs under other operating conditions.
