Description

Technical Field

[0001] The present invention relates to the technical field of finite element simulation modeling, and in particular to a method, system, terminal and storage medium for determining failure parameters of a honeycomb aluminum barrier model. Background Art

[0002] In the process of automobile safety assessment and design, collision tests and their simulation analysis play a vital role. With the development of the automobile industry and the continuous improvement of safety standards, automobile collision tests need to focus not only on the crashworthiness of the entire vehicle, but also on the comprehensive evaluation of the deformation of the barrier during the collision from the perspective of collision compatibility. As a key component of collision impact, the design and simulation accuracy of the barrier directly affect the accuracy and reliability of the collision simulation results.

[0003] First generation finite element barrier model: The model at this stage mainly relies on solid elements for stiffness equivalence, and simulates the adhesive effect by defining thin solid elements in the junction area between the honeycomb block and the partition. However, since the early evaluation specifications did not pay much attention to the deformation of the barrier itself, most models did not deeply consider the complex mechanism of adhesive failure, resulting in the limitations of the model in collision simulation.

[0004] Second-generation finite element barrier model: With the advancement of technology, the second-generation model uses shell elements to simulate honeycomb aluminum blocks, which significantly improves the calculation efficiency and accuracy. By adjusting the size of model units, using node variable thickness or inverse fitting of material parameters and other technical means, the overall stiffness of the honeycomb aluminum block is equivalent. Despite this, the model still faces challenges in adhesive simulation, because the bonding method between shell units and solid units is difficult to accurately reflect the actual adhesive failure process, which can easily lead to unreasonable penetration during the simulation process.

[0005] Dilemma of adhesive simulation: Traditional adhesive simulation methods mostly use solid element filling method, which is suitable for the connection of parallel or nearly parallel parts. However, in honeycomb aluminum barriers, the bonding between honeycomb aluminum blocks and partitions is mostly vertical, making traditional methods difficult to apply. Although the use of beam elements or Tied contact can partially solve the bonding problem, it is easy to cause penetration and the failure definition is complicated, affecting the accuracy of the model.

[0006] Limitations of existing solutions: Existing research focuses on the stiffness equivalence and modeling of honeycomb aluminum itself, while the improvement of adhesive simulation accuracy is relatively lagging behind. Even if innovative methods such as flange shell elements are used to simulate adhesive connections, there are still problems such as difficulty in reverse calculus of adhesive parameters and easy penetration with other shell elements. In addition, even if the adhesive failure force value is obtained through physical tests, there is still the problem of how to accurately apply it in the finite element model.

[0007] In summary, the existing finite element barrier model has obvious deficiencies in adhesive simulation, which limits the application accuracy and reliability of the model in complex collision scenarios. Summary of the invention

The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0050] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0051] Example

[0052] This embodiment provides a method for determining failure parameters of a honeycomb aluminum barrier model. The method flow is as follows: Figure 1 As shown, including:

[0053] S01: Obtain a preset honeycomb aluminum barrier adhesive equivalent model and a honeycomb aluminum barrier entity model;

[0054] S02: obtaining the deformation amount, adhesive failure degree information and loading force-displacement curve of each honeycomb aluminum block in the honeycomb aluminum barrier entity model when the honeycomb aluminum barrier entity model is subjected to a quasi-static loading test;

[0055] S03: Initializing a preset honeycomb aluminum barrier adhesive equivalent model to obtain an initialized honeycomb aluminum barrier adhesive equivalent model;

[0056] S04: adjusting the initialized honeycomb aluminum barrier adhesive equivalent model to obtain a targeted honeycomb aluminum barrier adhesive equivalent model, wherein the deformation amount, adhesive failure degree information and loading force-displacement curve of each honeycomb aluminum block in the targeted honeycomb aluminum barrier adhesive equivalent model are consistent with the deformation amount, adhesive failure degree information and loading force-displacement curve of each honeycomb aluminum block in the honeycomb aluminum barrier entity model;

[0057] S05: Determine the corresponding failure parameters of the honeycomb aluminum barrier entity model according to the targeted honeycomb aluminum barrier adhesive equivalent model.

[0058] In step S01, before obtaining the preset honeycomb aluminum barrier adhesive equivalent model, the method further includes: constructing the honeycomb aluminum barrier adhesive equivalent model, including:

[0059] The initial model parameters are used to construct the equivalent honeycomb aluminum block and equivalent partition of the honeycomb aluminum barrier adhesive equivalent model.

[0060] The equivalent honeycomb aluminum block and the equivalent partition are arranged according to a preset relative relationship to obtain a reference honeycomb aluminum barrier adhesive equivalent model;

[0061] The preset adhesive constraint model is used to connect the equivalent honeycomb aluminum block in the reference honeycomb aluminum barrier adhesive equivalent model with the adhesive of the equivalent partition to obtain the preset honeycomb aluminum barrier adhesive equivalent model.

[0062] In one embodiment, the constructed honeycomb aluminum barrier adhesive equivalent model is as follows: Figure 2As shown, it is composed of 7 independent honeycomb aluminum blocks, which are fixed and assembled by three main sealing plates and their adhesives. The side length of the barrier finite element model is 20 mm, and the total number of units in the barrier model does not exceed 900,000 units. Mainly from the perspective of collision calculation efficiency and calculation accuracy, the honeycomb aluminum cross-section is hexagonal, and a single side is composed of 3 rows of grids. The average grid of the barrier is 5 mm. In one embodiment, the initial model parameters include setting the side length of the honeycomb aluminum block 1-1 to 10.7 mm, the side length of the honeycomb aluminum blocks 1-2 and 3-1 to 16 mm, and the side length of the honeycomb aluminum blocks 2, 4 and 3-2 to 5.7 mm.

[0063] In one embodiment, the equivalent honeycomb aluminum block and the equivalent partition are arranged according to a preset relative relationship to obtain a reference honeycomb aluminum barrier adhesive equivalent model, including:

[0064] The connection nodes of the equivalent honeycomb aluminum block in the x-axis direction in the coordinate system are arranged in a manner that they coincide with the connection nodes of the equivalent partition in the x-axis direction in the coordinate system to obtain a reference honeycomb aluminum barrier adhesive equivalent model. The arrangement is made according to the preset relative relationship of this embodiment, so that the loading force of the collision overshoot honeycomb aluminum block can be directly transferred to the partition. Figure 3 The relative relationship between the honeycomb aluminum block and the partition at a certain local position, the nodes in the x direction completely overlap. The distance between the two nodes is 0.25mm, which is half the thickness of the partition, and the model does not produce initial penetration problems.

[0065] In one embodiment, a preset adhesive constraint model is used to connect the equivalent honeycomb aluminum block in the reference honeycomb aluminum barrier adhesive equivalent model with the adhesive of the equivalent partition to obtain the preset honeycomb aluminum barrier adhesive equivalent model. Since the adhesive between the honeycomb aluminum block and the partition may separate to varying degrees depending on the stress conditions during the simulation or test, the constraint equivalent modeling method needs to take into account the failure definition of the constraint. In one embodiment, the keyword *CONSTRAINED_SPOWELD is used to achieve the invisible or implicit equivalence of the adhesive. This equivalent modeling method can define failure through the axial force and tangential force of the connection between nodes.

[0066] In one embodiment, the constraint failure information in the preset adhesive constraint model is characterized by the following formula:

[0067]

[0068] Among them, f n and f s denote the axial interface force and shear interface force of the equivalent constraint, S n and S s They represent the ultimate axial force and ultimate shear force values ​​respectively, n and m are the corresponding exponential coefficients, usually 2.

[0069] In this embodiment, a preset adhesive constraint model is used to connect the equivalent honeycomb aluminum block in the reference honeycomb aluminum barrier adhesive equivalent model with the adhesive of the equivalent partition, which can avoid the penetration problem between the one-dimensional unit and the shell unit caused by the use of beam units or welding point units. Figure 4 This is a schematic diagram of a connection through an equivalent constraint. This connection is not a unit in a certain sense, that is, in the collision simulation, there is no need to consider the contact between this connection and the surrounding shell units or solid units, which can effectively avoid negative volume or penetration problems.

[0070] In step S02, the deformation amount, adhesive failure degree information and loading force-displacement curve of each honeycomb aluminum block in the honeycomb aluminum barrier entity model are obtained when the honeycomb aluminum barrier entity model is subjected to a quasi-static loading test;

[0071] In one embodiment, the adhesion failure phenomenon between honeycomb aluminum and aluminum plate is obtained by performing a quasi-static crushing test on the honeycomb aluminum barrier entity model. Because the side length and strength of each honeycomb aluminum block are different, the adhesive failure force will also have a certain deviation. It is necessary to perform a corresponding quasi-static test on each honeycomb aluminum block. In order to obtain adhesive failure at both ends of the honeycomb aluminum block away from the crushing area during the quasi-static crushing process, in one embodiment, a semi-cylinder with a length, width and height of 200 mm and a test pressure head of 100 mm in diameter is selected. During the entire loading process, the upper partition is in contact with the pressure head, and the lower partition is completely fixed. Figure 5 As shown. During the entire quasi-static loading process, the honeycomb aluminum in the pressure head area is compressed and deformed, but the honeycomb aluminum at both ends will bend and deform toward the pressure head side. As the crushing amount of the pressure head gradually increases, the adhesive between the honeycomb aluminum on both sides and the partition will fail. The deformation of the honeycomb aluminum, the degree of adhesive failure, and the loading force-displacement curve are recorded for finite element simulation and inverse analysis of adhesive failure parameters.

[0072] In step S03, the preset honeycomb aluminum barrier adhesive equivalent model is initialized to obtain an initialized honeycomb aluminum barrier adhesive equivalent model, including:

[0073] Determine the initial limit axial force and the initial limit shear force based on the failure force information of the average disassembly of the viscose base material level test;

[0074] The preset honeycomb aluminum barrier adhesive equivalent model is initialized using the initial limiting axial force and the initial limiting shear force to obtain an initialized honeycomb aluminum barrier adhesive equivalent model.

[0075] In one embodiment, for the preset honeycomb aluminum barrier adhesive equivalent model, the initial limit axial force and the limit shear force values ​​are set to 500N and 1000N according to the failure force recommendation of the average disassembly of the adhesive base material level test.

[0076] In step S04, the initialized honeycomb aluminum barrier adhesive equivalent model is adjusted to obtain a targeted honeycomb aluminum barrier adhesive equivalent model, wherein the deformation amount, adhesive failure degree information and loading force-displacement curve of each honeycomb aluminum block in the targeted honeycomb aluminum barrier adhesive equivalent model correspond to the deformation amount, adhesive failure degree information and loading force-displacement curve of each honeycomb aluminum block in the honeycomb aluminum barrier physical model;

[0077] In one embodiment, based on the initialization of the honeycomb aluminum barrier adhesive equivalent model, batch definition is performed in the *CONSTRAINED_SPOTWE:D keyword. Through multiple rounds of iterations, the deformation, adhesive failure degree information and loading force-displacement curve of each honeycomb aluminum block in the quasi-static crushing simulation model are made consistent with the deformation, adhesive failure degree information and loading force-displacement curve of each honeycomb aluminum block in the honeycomb aluminum barrier solid model. Through such finite element alignment and parameter inversion, the ultimate axial force and shear force of the adhesive between the honeycomb aluminum and the partition under quasi-static crushing are obtained to be 350N and 700N respectively.

[0078] verify

[0079] The automobile collision honeycomb aluminum barrier is mainly used for dynamic impact test and simulation. Honeycomb aluminum has an enhanced effect of entraining air in the high-speed extrusion process, which may also have a certain impact on the failure of the adhesive. We use the equivalent adhesive modeling and its failure parameters obtained by calibration to verify the dynamic impact condition of the complete barrier finite element model, such as Figure 6 As shown in the figure, it is a simulated barrier deformation diagram obtained by testing under the 35km / h rigid Tube collision condition. Overall, it can be seen that the first layer of honeycomb aluminum and the second layer of honeycomb aluminum fail in the partition glue area, and the scope of the failure is basically consistent with the scope of the actual test collision failure. The deformation mode of the honeycomb or the overall deformation mode of the barrier is also the same. Figure 7 The curves shown are the collision force of the middle column, the collision force of the tubes on the left and right sides, and the acceleration of the trolley during the entire collision test and simulation process. The consistency of the various curves is very good, indicating that on the one hand, the stiffness equivalent modeling of the honeycomb aluminum barrier is accurate, and secondly, the adhesive equivalent modeling of the honeycomb aluminum and the partition is reasonable and the failure parameters are reasonable and accurate. Overall, the accuracy of the entire barrier finite element model is reliable and can be used for simulation and research of various types of collision conditions.
