[0055] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0056] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0057] Impact-resistant materials are materials that can resist and absorb impact energy. They are widely used in the fields of protection and safety, such as bulletproof vests, helmets, sports protective gear, building materials, medical equipment and other products. The structures of impact-resistant materials include regular hexagons, rectangles, circles and other structures. When constructing impact-resistant materials, it is usually difficult to adjust the structure of the impact-resistant materials and to quantitatively adjust the size of the honeycomb details, which is not conducive to optimizing specific impact resistance.

[0058] To solve the above problems, the present application proposes a method for constructing an impact-resistant material, such as Figure 1 As shown, the method includes:

[0059] In S101, the planar position of the seed point is determined according to the geometric features of the honeycomb structure.

[0060] The shape of the basic unit in the honeycomb structure in the embodiment of the present application may include polygons, circles, ellipses, etc. The polygons may include regular hexagons, squares, other regular polygons, etc. The following is an example of the shape of the basic unit with a regular hexagonal structure as an example. It is understandable that other polygonal shapes may also be constructed in a similar manner.

[0061] The seed point in the embodiment of the present application is the initial point determined when generating the impact-resistant material.

[0062] When constructing the plane positions of the seed points, the first circle of seed points may be determined first. For example, the first circle of seed points may be determined to be the origin positions in a preset plane coordinate system.

[0063] After the first circle of seed points is confirmed, a first regular hexagon with a side length of the first distance can be constructed based on the first circle of seed points as the center, and the second circle of seed points can be determined based on the vertices of the first regular hexagon. The first distance can be the side length of the regular hexagon. Figure 2 As shown, the positions of the second circle of seed points can be determined based on the six vertices of the first regular hexagon.

[0064] According to the similar determination method of the second circle seed points, a second regular hexagon with a side length of the second distance can be constructed based on the first circle seed points as the center, and the third circle seed points can be determined based on the second regular hexagon. The second distance can be 2 times the first distance. When determining the third circle seed points based on the second regular hexagon, the second circle points included in the second regular hexagon can be determined based on the side length of the regular hexagon per unit of the first distance. For example Figure 2 As shown, assuming that the side length of the first regular hexagon is 1, the side length of the second regular hexagon is 2, and the side length of the second regular hexagon is divided according to the side length of the first regular hexagon to determine the third circle of seed points. According to this logic, the seed points of the predetermined number of circles are obtained.

[0065] In S102, the seed point is mapped to a preset spherical surface, an initial honeycomb structure corresponding to the spherical surface is determined by using an Andrew algorithm, and an elevation of the seed point mapped to the preset spherical surface is determined.

[0066] After obtaining the positions of the seed points in the two-dimensional plane, the determined seed points can be mapped to the spherical surface. For example, the seed points of the plane can be uniformly mapped to the standard spherical surface, so as to facilitate uniform triangulation using the Andrew algorithm.

[0067] The mapping formula can be:

[0068]

[0069] In the formula, represents the number of seed points in the i-th circle, θ ij represents the azimuth of the jth seed point in the i-th circle, represents the elevation angle of the seed point in the i-th circle, R max is the total number of circles of the seed point. Figure 3 As shown, when mapping the seed point of the plane to the sphere, the seed point at the origin position (ie, when i=1) can be directly mapped vertically to the vertex of the unit sphere.

[0070] The seed points are mapped to the sphere to obtain the mapping points. The Andrew algorithm can be used to triangulate the mapping points. The triangulation can be performed according to the position of the mapping points to obtain the following: Figure 4 The initial uniform triangular mesh shown in the figure. Andrew's algorithm is a triangulation algorithm for point sets in three-dimensional space. It constructs a triangular mesh by connecting point sets. The center position of each triangular mesh can be calculated and the center positions of the triangular meshes can be connected to obtain the following: Figure 4 The initial spherical honeycomb structure shown on the right.

[0071] When the seed point of the plane is mapped to the spherical surface, the mapping distance between the seed point and the mapping point is the elevation corresponding to the mapping point.

[0072] In S103, a custom weighted distance field of the plane where the seed point is located is determined by superimposing a custom attenuation function and a scaling factor according to the elevation.

[0073] The elevation of the seed point on the sphere (which can be a standard unit sphere) can be mapped as a weight reference, and a weighted distance field with uniform gradient is constructed in the initial seed plane (the plane where the seed point is located). By superimposing the exponential decay function and scaling factor in the predetermined direction, the construction of the weighted distance field with a custom evolutionary gradient is realized. The predetermined direction can include the direction from the center to the outside, or from the outside to the center. The weight of any point in the weighted distance field can be determined according to the following calculation formula:

[0074]

[0075] In the formula, z is the elevation coordinate of any point on the sphere, α is the weight adjustment coefficient, β is the exponential decay coefficient, and Q i is the weight of the seed point in the i-th circle. The determined weighted distance field result can be expressed as Figure 5As shown, different colors represent weights of different sizes, the coefficient of the center position of the weight distance field is 1, and the edge value of the weight distance field is 0.

[0076] The weighted distance field represents a weight coefficient determined based on the mapping distance, attenuation coefficient, and weight adjustment coefficient of any point on the plane where the seed point is located.

[0077] In S104, the projection position of the spatial position of the seed point on the spherical surface on the weighted distance field is determined, the position of the seed point is updated according to the projection position and the weighted distance field, and iterative calculation is performed according to the updated seed point until a preset iteration requirement is met.

[0078] According to the spatial position of the seed point mapped to the sphere, the vertical projection position of the mapped point on the weighted distance field can be determined. According to the vertical projection position and the weight coefficient corresponding to the seed point calculated by the weighted distance field, the weighted offset center of the triangular mesh obtained by the Andrew algorithm can be calculated. When determining the weighted offset center of the triangular mesh, such as Figure 6 As shown, three weighted perpendicular bisectors can be constructed according to the weight of each point in the triangle, that is, the position of the offset center is determined according to the weight coefficient corresponding to the mapping point, and the vertical line determined by the offset center is the weighted perpendicular bisector, so that it satisfies:

[0079]

[0080] In the formula, x A , x B , x C is the coordinates of each vertex of the triangle mesh, O AC , O BC , O AB is the midpoint of each edge of the triangle mesh, w A , w B , w C is the weight coefficient of each vertex in the triangle mesh.

[0081] Through the formula satisfied by the weighted perpendicular bisector, three weighted perpendicular bisectors can be constructed, such as Figure 6 As shown, these three weighted perpendicular bisectors will converge at three points, which are I A , I B , I C The weighted center position of the triangle can be determined based on the three intersection points I A , I B , I C The coordinates of the three points can be used to determine the value, for example, the mean of the coordinates of the three points that intersect.

[0082] According to the weighted center position of the triangular mesh, the weighted center position of the regular hexagonal honeycomb can be further calculated as follows:

[0083]

[0084] In the formula, x VC is the weighted center of the hexagonal honeycomb, is the average weight of the three points of the triangle mesh, W tt is the sum of the six average weights, is the weighted center of the ith triangle.

[0085] The weighted position of the seed point is updated according to the determined weighted center of the cell, and the cell structure is re-divided according to the weighted position of the seed point, and iterative updates are performed according to the divided cell structure. Figure 7 As shown, through repeated iterations, as the number of iterations M increases, the error between the position of the updated seed point and the target position becomes smaller and smaller, until the predetermined requirements are met, or the preset number of iterations is reached, for example, the number of iterations is set to 50, and when M=50, the construction of the gradient honeycomb is achieved.

[0086] In S105, the spherical honeycomb structure corresponding to the updated seed point is mapped to a plane to obtain a plane structure diagram of the impact-resistant material.

[0087] After obtaining the spherical honeycomb structure, the spherical honeycomb structure can be mapped to the plane to obtain Figure 8 The plan view of the impact-resistant structure with gradient honeycomb size is shown.

[0088] In possible implementations, the required shape of the impact-resistant structure has different requirements, such as Figure 8 As shown, based on the constructed plan view of the circular impact-resistant structure, by constructing a mapping function, the plan view of the circular impact-resistant structure can be mapped into a plan view of an impact-resistant structure of other shapes according to different scene requirements. For example, it can be mapped into a plan view of an impact-resistant structure in a geometric form such as a square or a rectangle.

[0089] For example, the plane diagram of the impact-resistant structure mapped from a circle to a square can be mapped using the following mapping function:

[0090]

[0091] In the formula, x img ,y img is the coordinate position after mapping, u and v are the coordinate positions before mapping.

[0092] In a possible implementation, after obtaining a plan view of the impact-resistant structure of a predetermined shape, such as a circular or square plan view of the impact-resistant structure, it can be further lifted along a predetermined direction. Fig. 9 As shown, the impact-resistant material structure with different gradient distributions can be obtained by pulling it up in the longitudinal direction. In addition, the embodiment of the present application can also conveniently adjust the wall thickness of the gradient honeycomb structure by geometrically scaling the size of each honeycomb. The scaling coordinate calculation formula can be calculated as follows:

[0093]

[0094] In the formula, x i is the coordinate position before scaling, is the coordinate position after scaling, is the jth cell center, and η is the scaling factor. Fig.10 As shown, by adjusting different scaling factors, for example, when η is 0.8, 0.9 and 0.6 respectively, honeycomb structures with different wall thicknesses can be obtained.

[0095] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
