[0044] Before the specific embodiment of the present application is described, the overall concept of the present application is described as follows:
[0045] The present application is mainly developed in the process of compressive testing of the mechanical properties of lattice materials. In the prior art, the stress concentration often occurs at the connection between the struts of the structure in the testing process, which may cause the stress-strain curve of the structure to enter the platform stress region and then appear obvious softening phenomenon.
[0046] The inventor found that the main reason for the above problems is that the connection between the struts of the structure in the prior art is stress concentrated, and the structure is unevenly stressed. Therefore, using an arc to replace the straight-line turning corner in the prior structure can avoid the above problems. Therefore, the present application proposes a generation method of a bionic three-dimensional corrugated structure unit cell, including the following steps:
[0047] Obtaining a standard honeycomb structure, performing a first initial transformation on the standard honeycomb structure to obtain a two-dimensional corrugated lattice structure unit cell;
[0048] Performing a first spatial transformation on the two-dimensional corrugated lattice structure unit cell to obtain a preliminary structure of a three-dimensional corrugated structure unit cell;
[0049] Performing a second spatial transformation on the two-dimensional corrugated lattice structure unit cell to obtain a hollow structure of a three-dimensional corrugated structure unit cell;
[0050] Performing a composite operation on the preliminary structure of the three-dimensional corrugated structure unit cell and the hollow structure of the three-dimensional corrugated structure unit cell to obtain a bionic three-dimensional corrugated structure unit cell.
[0051] After the overall concept of the present application is introduced, in order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application is further described in detail below by combining the specific embodiments with the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0052] In one embodiment, as shown in Figure 1 a generation method of a bionic three-dimensional corrugated structure unit cell is provided, including the following steps:
[0053] In step S101, a standard honeycomb structure is obtained, and a first initial transformation is performed on the standard honeycomb structure to obtain a two-dimensional corrugated lattice structure unit cell.
[0054] Specifically, a classical honeycomb structure is first obtained, which is generated by extracting the typical structural features of a traditional two-dimensional honeycomb. The standard honeycomb structure is shown in FIG. 1. A first initial transformation is performed on the standard honeycomb structure. For example, the width of the curve of the standard honeycomb structure is adjusted to a specific multiple of the original width, or the width of the curve of the standard honeycomb structure is adjusted to a specific value. Figure 2
[0055] In this embodiment, the width of the curve of the standard honeycomb structure is adjusted. The strength of the lattice structure can be enhanced to adapt to different material requirements.
[0056] On this basis, specifically, the curve of the standard honeycomb structure is replaced with a sinusoidal curve to obtain a two-dimensional corrugated lattice structure. The two-dimensional corrugated lattice structure is shown in FIG. 2. The sinusoidal curve can be represented by the following formula: Figure 3
[0057]
[0058] where L represents the span, A represents the amplitude, and x represents the independent variable value in the rectangular coordinate system, and y represents the dependent variable value corresponding to the function in the same rectangular coordinate system.
[0059] A unit cell is cut from the two-dimensional corrugated lattice structure to obtain a two-dimensional corrugated lattice structure unit cell. The two-dimensional corrugated lattice structure unit cell is shown in FIG. 3. The in-plane thickness of the two-dimensional corrugated lattice structure unit cell is t. Figure 4
[0060] In this embodiment, the span and amplitude set are input into the sine formula, and the straight line structure in the standard honeycomb structure is replaced with a sinusoidal curve, which reduces the bending angle and makes the stress more balanced, thereby obtaining a more stable mechanical response.
[0061] In step S102, a first spatial transformation is performed on the two-dimensional corrugated lattice structure unit cell to obtain a preliminary structure of a three-dimensional corrugated structure unit cell.
[0062] On this basis, specifically, the two-dimensional corrugated lattice structure unit cell is rotated by 90 degrees around its symmetry axis to obtain a horizontal two-dimensional corrugated lattice structure unit cell, which is overlapped and combined with the center of the two-dimensional corrugated lattice structure unit cell at its original position to obtain a preliminary structure of a three-dimensional corrugated structure unit cell. The preliminary structure of the three-dimensional corrugated structure unit cell is shown in FIG. 4. The out-of-plane thickness of the two-dimensional corrugated lattice structure unit cell is b. Figure 5
[0063] In the embodiment, the two-dimensional corrugated lattice unit cell is rotated by 90 degrees around the self-symmetry axis to be combined with the original two-dimensional corrugated lattice unit cell to obtain a preliminary structure of a three-dimensional corrugated lattice unit cell, which converts two-dimensional to three-dimensional and improves the three-dimensionality of the lattice structure and reduces the mass of the lattice structure.
[0064] In step S103, a second spatial transformation is performed on the two-dimensional corrugated lattice unit cell to obtain a hollow structure of the three-dimensional corrugated lattice unit cell.
[0065] Specifically, the two-dimensional corrugated lattice unit cell is rotated by 90 degrees clockwise around the center of mass to obtain a side two-dimensional corrugated lattice unit cell, and the side two-dimensional corrugated lattice unit cell is arrayed four times in a ring direction to obtain a hollow structure of the three-dimensional corrugated lattice unit cell. The planes of each array are perpendicular to each other, and the hollow structure is obtained by arraying four times in the ring direction. A schematic diagram of the hollow structure of the three-dimensional corrugated lattice unit cell is shown in FIG. 3. Figure 6
[0066] In the embodiment, the side two-dimensional corrugated lattice unit cell is arrayed four times in the ring direction to form a hollow cube structure, which enhances the stability of the lattice structure.
[0067] In step S104, the preliminary structure of the three-dimensional corrugated lattice unit cell and the hollow structure of the three-dimensional corrugated lattice unit cell are combined to obtain a bionic three-dimensional corrugated lattice unit cell.
[0068] Specifically, the preliminary structure of the three-dimensional corrugated lattice unit cell is inserted into the hollow structure of the three-dimensional corrugated lattice unit cell, and the centers of mass of the two structures coincide to obtain the bionic three-dimensional corrugated lattice unit cell. A schematic diagram of the structure of the bionic three-dimensional corrugated lattice unit cell is shown in FIG. 4. Figure 7
[0069] In the embodiment, the preliminary structure is combined with the hollow structure, the mass of the lattice structure with the same volume is reduced, and the energy absorption performance is improved.
[0070] After step S104, the bionic three-dimensional corrugated lattice unit cell is scaled by a predetermined ratio to obtain scaled unit cells corresponding to the bionic three-dimensional corrugated lattice unit cell, respectively.
[0071] The bionic three-dimensional corrugated lattice unit cell and the scaled unit cells are arrayed and filled into a space of a predetermined size to obtain a three-dimensional corrugated lattice structure.
[0072] The three-dimensional corrugated lattice structure includes a three-dimensional corrugated non-gradient lattice structure and a three-dimensional corrugated gradient lattice structure.
[0073] The three-dimensional corrugated non-gradient lattice structure is generated by arraying the bionic three-dimensional corrugated lattice unit cells or the scaled unit cells with the same size.
[0074] The three-dimensional corrugated gradient lattice structure is generated by different sizes of biomimetic three-dimensional corrugated structure unit cells and scaled unit cells.
[0075] Specifically, the biomimetic three-dimensional corrugated structure unit cells are scaled along the centroid by a preset ratio to obtain scaled unit cells corresponding to the biomimetic three-dimensional corrugated structure unit cells respectively. For example, the original biomimetic three-dimensional corrugated structure unit cell has a length, a width and a height of 30 mm, and the biomimetic three-dimensional corrugated structure unit cell is scaled by 0.75 times along the centroid to obtain a scaled unit cell with a length, a width and a height of 22.5 mm.
[0076] The biomimetic three-dimensional corrugated structure unit cells and the scaled unit cells are filled into a preset space to obtain a three-dimensional corrugated lattice structure. For example, a space with a preset length and width of 60 mm and a height of 90 mm is filled with biomimetic three-dimensional corrugated structure unit cells with a length, a width and a height of 30 mm in the x and y directions for 22 times and in the z direction for 3 times.
[0077] The three-dimensional corrugated lattice structure includes a three-dimensional corrugated non-gradient lattice structure and a three-dimensional corrugated gradient lattice structure.
[0078] The three-dimensional corrugated non-gradient lattice structure is generated by an array of unit cells of the same size, i.e., only unit cells of a single size are filled into the preset space.
[0079] The three-dimensional corrugated gradient lattice structure is generated by an array of unit cells of different sizes, i.e., unit cells of different sizes are filled into the preset space. The interfaces between adjacent subspaces can be connected by an interlayer.
[0080] In this embodiment, unit cells of different sizes are filled into a preset space to generate a three-dimensional corrugated gradient lattice structure, which effectively eliminates the instability of the deformation mechanism of the lattice structure under stress, has the advantages of high energy absorption density, small recoil force and easy integration with additive manufacturing.

Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.
