[0002] In the structural design of high-end equipment, traditional solutions are forced to adopt a "functional superposition" model due to the limited functionality of materials. For example, the boom positioning node of a high-speed train is an elastomer made of vulcanized rubber and metal, which provides flexible connection and vibration damping. Current approaches to applying new materials are often limited to replacing a single traditional material, without breaking through the inherent multi-material superposition design framework. Therefore, how to reconstruct traditional superposition design components using a single multi-functional component is a pressing technical problem that needs to be solved. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0025] The multifunctional integrated component design method of this invention, as described in the embodiments, is as follows: Figure 1As shown, the procedure includes steps S110 to S130.
[0026] Step S110: Perform functional requirements analysis, integrated structural design and simulation verification on the target component, and determine the target material system that meets the target performance parameters corresponding to the functional requirements of the target component under various working conditions.
[0027] Specifically, the target material system that meets the target performance parameters corresponding to the functional requirements of the target component under various working conditions can be obtained by comprehensively analyzing three pre-created basic databases: material spectrum performance database (e.g., superelastic alloy material spectrum performance database), component working condition and demand database, and integrated structural design application case database (e.g., cross-domain superelastic alloy engineering application case database).
[0028] Specifically, step S110 includes: Step S111: Perform functional requirement analysis on the target component to obtain target performance parameters that meet the functional requirements under various working conditions.
[0029] For example, such as Figure 2 As shown, a functional analysis of the primary suspension system of a rail vehicle is performed, with the swing arm positioning node in the primary suspension system as the target component. The corresponding functional requirements are: (1) to transmit traction and braking forces radially; and (2) to be able to deflect along the axis in the axial direction. Specifically, functional analysis can be performed by calling a large model or intelligent agent, that is, by inputting the target component name and application scenario into the large model or intelligent agent, and obtaining the corresponding functional requirements output by the large model or intelligent agent.
[0030] After obtaining the functional requirements, based on the overall design requirements of a certain type of vehicle, the target performance parameters that meet the functional requirements of the target component under each working condition are obtained by querying the component working condition and requirement database. For example, according to the above functional requirements (1) and (2), the working condition and requirement database of the axle box swing arm positioning node is queried, and the target performance parameters of the swing arm positioning node are obtained as follows: radial stiffness is 1×10 4 ±500 N / mm, axial stiffness 5×10 3 ±250N / mm.
[0031] Step S112: Match at least one multifunctional material system according to the functional requirements. It is understood that materials that may meet the functional requirements can be pre-selected based on experience. For example, for the swing arm positioning node of the primary suspension system in rail vehicle equipment, considering its load-bearing and deformation requirements, an alloy material with high strength and superelasticity can be selected as a candidate multifunctional material system for the target material system. Specifically, multifunctional material system analysis can be performed by calling a large model or intelligent agent; that is, the functional requirements are input into the large model or intelligent agent, and the corresponding multifunctional material system is obtained from the output of the large model or intelligent agent.
[0032] Step S113: Based on the functional requirements and multifunctional material system, an integrated structural design is performed on the target component, and simulation verification is conducted based on the integrated structural design and working conditions to determine the material parameters that meet the target performance parameters. Traditional designs are limited by the single properties of materials, using vulcanization design of steel and rubber structures to achieve load-bearing and deformation. Due to the sensitivity of rubber materials to the working environment (such as aging caused by ultraviolet radiation), the lifespan of the swing arm positioning node is limited. Therefore, an integrated structural design is adopted in this embodiment.
[0033] Specifically, by querying the database of integrated structural design application cases for multifunctional material systems, an integrated structural design that meets the functional requirements can be selected, i.e., a topological structure of the target component can be chosen. Multifunctional material systems have exploratory design cases in many fields, and similar cases can be searched and compared to select an integrated structural design that closely matches the functional requirements.
[0034] For example, for the swing arm positioning node, such as Figure 3 and 4 As shown, by querying the cross-domain superelastic alloy engineering application case database, two topology design structures were obtained for the integrated structure design: spoke structure design and engine blade structure design.
[0035] Simulation verification is performed based on the integrated structural design and operating conditions to determine the material parameters that meet the target performance parameters. Specifically, the operating condition parameters, structural parameters, materials corresponding to the multifunctional material system, and their material parameters are input into a pre-established simulation model for the integrated structural design (such as a simulation model built using ABAQUS), and the material parameters that meet the target performance parameters are obtained through simulation.
[0036] For example, for the boom positioning node, the input operating parameters are: radial load 13.5KN, axial load 30KN, and the material is a hyperelastic alloy, such as a nickel-titanium shape memory alloy with a tensile strength of 500MPa~800MPa and an elongation at break of 4%~12%. Simulations are performed on the integrated structural designs of the spoke structure and the engine blade structure. During simulation, the material parameters can be adjusted within a predetermined range until the target performance parameters (e.g., radial stiffness 1×10⁻⁶) are met. 4 ±500 N / mm, axial stiffness 5×10 3±250N / mm). Simulation verification was performed on the two design schemes. Based on the simulation results shown in Tables 1a, 1b, 2a and 2b, the material parameters of the superelastic alloy were initially determined by the stress-strain range corresponding to the four structural parameters from OPT1 to OPT4 (such as changes in spoke diameter, changes in engine blade thickness and width, etc.). For example, the tensile strength is not less than 750 MPa and the elongation at break is not less than 5%.
[0037] For example, in the spoke structure design, the spoke diameter parameter Ax1 is taken as 0.8 mm or 0.9 mm, and the angle parameter Ax2 is taken as 30°. o Or 45 o Four structural parameters, OPT1 to OPT4, were obtained for the spoke structure design: OPT1 uses Ax1=0.8, Ax2=30°; OPT2 uses Ax1=0.8, Ax2=45°; OPT3 uses Ax1=0.9, Ax2=30°; and OPT4 uses Ax1=0.9, Ax2=45°. Based on these four structural parameters, Tables 1a and 1b show the preliminary simulation results of the spoke structure design schemes under radial and axial loads, respectively.
[0038] Similarly, for example, for engine blade structure design, using different combinations of blade thickness and blade angle, four structural parameters OPT1 to OPT4 of engine blade structure design can also be obtained. Based on the four structural parameters OPT1 to OPT4 of engine blade structure design, Tables 2a and 2b show the preliminary simulation results of engine blade structure design schemes under radial load and axial load, respectively.
[0039] Step S114: Match the target material system that satisfies the material parameters in the material spectrum performance database of the multifunctional material system. Specifically, by querying the material spectrum performance database, find the material system that satisfies each material parameter. For example, by querying the superelastic alloy material spectrum performance database, find a material system with an alloy tensile strength of not less than 750 MPa and an elongation at break of not less than 5%. For example, the target material system is a nickel-titanium shape memory alloy.

[0041] Table 1b: Preliminary simulation results of the spoke structure design scheme under axial load
[0042] Table 2a: Preliminary simulation results of engine blade structure design scheme under radial load
[0043] Table 2b: Preliminary simulation results of engine blade structure design scheme under axial load
[0044] Step S120: Establish a design mapping relationship model among the structural parameters of the integrated structural design, the material parameters of the target material system, and the target performance parameters.
[0045] For example, the design mapping model is as follows: Figure 5 As shown, this is a neural network model built based on Back Propagation.
[0046] For example: The target performance parameter of the target component is: radial stiffness z1 = 1 × 10 4 ±500 N / mm, axial stiffness z2 = 5 × 10 3 ±250N / mm.
[0047] Simulation input: Structural parameters A of the target component: Ax1, Ax2, ..., Ax i (Ax1 spoke diameter, Ax2 spoke angle, etc.).
[0048] Material parameters B: Bx1, Bx2, ..., Bx j (e.g., Bx1 yield strength, Bx2 tensile strength at break, etc.).
[0049] Simulation output: Y1, Y2, ..., Y k (Y1 radial stiffness, Y2 axial stiffness, Y3 maximum stress, Y4 maximum strain, etc.).
[0050] The training dataset for constructing the design mapping relationship model based on simulation results is shown in Table 3 below.
[0051] Table 3 Training Dataset
[0052] The Back Propagation neural network model was trained based on the dataset in Table 3, and the mapping relationship model of the design was obtained after training.
[0053] Step S130: Based on the design mapping relationship model and target performance parameters, determine the structural and material parameters for the integrated structural design. A multi-objective optimization method (such as an evolutionary algorithm) can be used to solve for the Pareto front, thereby obtaining the structural and material parameters required for the integrated structural design. That is, in subsequent design of target components with different target performance parameters, the target performance parameters are used as optimization objectives, substituted into the design mapping relationship model, and the corresponding structural and material parameters are obtained in reverse.
[0054] Specifically, the process of solving for structural and material parameters by using the target performance parameters as the optimization objective is as follows: (1) Randomly initialize a group of candidate solutions in the input space (structural parameters, material parameters), that is, freely combine multiple initialized structural parameters and material parameters. Of course, constraints can also be added, such as the structural parameters being limited by the product size.
[0055] (2) Calculate the prediction performance parameters corresponding to each solution using the trained design mapping relationship model.
[0056] (3) The population is sorted according to the Pareto dominance relationship, that is, the calculation is performed for each combination of structural parameters and material parameters, and then the predicted performance parameters are sorted according to the proximity to the target performance parameters.
[0057] (4) A new generation of population is generated through selection, crossover, and mutation, and the process is iterated in a cycle, that is, to find a combination of structural parameters and material parameters that better meet the target performance parameters.
[0058] (5) Finally, a group of Pareto optimal solutions are obtained, which are distributed on the Pareto front. The optimal solution is the combination of structural and material parameters corresponding to the predicted performance parameters that are closest to the target performance parameters. For example, the target performance parameters include radial stiffness and axial stiffness. Different combinations of structural and material parameters will result in different predicted performance parameters. The radial stiffness and axial stiffness may fully meet the requirements of the target performance parameters, or the radial stiffness may meet the requirements while the axial stiffness is close to the requirements. Arrange the results of all predicted performance parameters and select according to the requirements.
[0059] The multifunctional integrated component design method in this embodiment analyzes the functional requirements of the target component, designs the integrated structure, and performs simulation verification to determine the target material system that meets the target performance parameters corresponding to the functional requirements of the target component under various working conditions. It establishes a design mapping relationship model among the structural parameters of the integrated structure design, the material parameters of the target material system, and the target performance parameters. Based on the design mapping relationship model and the target performance parameters, it determines the structural and material parameters of the integrated structure design. Through the entire design process, it achieves the replacement of the traditional material superposition design with a single multifunctional component, resulting in a simpler target component structure compared to traditional structures.
[0060] In some embodiments, after determining the structural parameters and material parameters of the integrated structural design based on the design mapping relationship model and target performance parameters, the method further includes: determining a customized material that satisfies the material parameters, wherein the customized material is obtained by adjusting the manufacturing process and composition-related key variables of the target material system.
[0061] It is understandable that after determining the material parameters, the existing target material system may not contain materials that fully meet those parameters. Therefore, it is necessary to determine customized materials that satisfy the material parameters. Customized materials can be obtained by adjusting key variables related to the manufacturing process and composition of the target material system.
[0062] In this embodiment, a material system with parameters close to those of the target material system can be used as a basis. By adjusting key variables related to the manufacturing process and composition of the target material system, that is, by finely designing and controlling the material system, a customized material that fully meets the material parameters can be obtained.
[0063] Furthermore, the key variables related to the manufacturing process and composition of the target material system are adjusted as follows: Identify the key component variables that affect each material parameter in the target material system and the key control variables in the preparation process.
[0064] The key component variables and key control variables in the preparation process are adjusted, and the material parameters are tested based on the adjusted material to obtain a customized material that meets the material parameters.
[0065] Taking the addition of vanadium to nickel-titanium shape memory alloy as an example: by adding vanadium to the nickel-titanium shape memory alloy, the alloy composition design is modified by alloying, the grain size is significantly refined, obvious lattice distortion is produced, and a dispersed strengthening phase is formed, which increases the critical stress of phase transformation.
[0066] In this embodiment, Ni 50 Ti 47 Based on the materials, the key component variables are the individual contents of nickel (Ni), titanium (Ti), and the newly added vanadium (V). Key control variables in the preparation process include temperature and pressure control. Based on this, there are five adjustment methods: Method 1: The alloy composition is Ni 50 Ti 47 Alloy of V3 (at.%).
[0067] 1. Raw material preparation: Weigh out nickel ingots, titanium ingots and vanadium granules, all with a purity of 99.99%.
[0068] 2. Vacuum melting: Place the raw material into the water-cooled copper crucible of the vacuum induction melting furnace, and evacuate to a vacuum level of 3×10. -3 After Pa, high-purity argon gas is introduced to -0.05 MPa. The mixture is melted at 1550℃ and held for 15 minutes, then poured into a copper mold. This melting process is repeated four times to obtain a homogeneous ingot.
[0069] 3. Homogenization heat treatment: The ingot is placed in a vacuum heat treatment furnace and held at 950°C for 10 hours, and then cooled with the furnace to eliminate component segregation in the ingot.
[0070] 4. Hot mechanical processing: The homogenized ingot is heated to 900℃ and hot forged in multiple passes. Then it is hot rolled at 850℃ to finally produce alloy bars with a diameter of 16mm.
[0071] 5. Aging treatment: The hot-rolled bars are aged at 500℃ and kept at that temperature for 1.5 hours before being removed and air-cooled.
[0072] Tests showed that the alloy bar had a room temperature hyperelastic stress plateau of 700 MPa, a tensile strength of 850 MPa, and an elongation at break of 20%.
[0073] Method 2: The preparation composition is Ni 49 Ti 47 V4 (atomic percentage) alloy.
[0074] 1. Raw material preparation: Weigh out nickel ingots, titanium ingots and vanadium granules, all with a purity of 99.9%.
[0075] 2. Vacuum melting: The process is the same as in method 1, and the melting process is repeated 3 times.
[0076] 3. Homogenization heat treatment: The ingot is held at 980℃ for 9 hours, and then cooled with the furnace.
[0077] 4. Hot mechanical processing: The ingot is heated to 920℃ for hot forging, and then hot rolled at 820℃ into a plate with a thickness of 8mm.
[0078] 5. Aging treatment: The hot-rolled sheet is aged at 480℃ for 2 hours, followed by air cooling.
[0079] Tests showed that the alloy plate had a room temperature hyperelastic stress plateau of 650 MPa, a tensile strength of 750 MPa, and an elongation at break of 17%.
[0080] Method 3: The preparation composition is Ni 51 Ti 47 Alloys with a V2 (atomic percentage) content.
[0081] 1. Raw material preparation: Weigh out nickel ingots, titanium ingots and vanadium granules, all with a purity of 99.9%.
[0082] 2. Vacuum melting: The process is the same as in method 1, and the melting process is repeated 3 times.
[0083] 3. Homogenization heat treatment: The ingot is held at 950℃ for 10 hours, and then cooled in the furnace.
[0084] 4. Hot mechanical processing: The ingot is heated to 900℃ for hot forging, and then hot rolled at 800℃ into a plate with a thickness of 6mm.
[0085] 5. Aging treatment: The hot-rolled sheet is aged at 450℃ for 5 hours, followed by air cooling.
[0086] Tests showed that the alloy plate had a room temperature hyperelastic stress plateau of 600 MPa, a tensile strength of 750 MPa, and an elongation at break of 15%.
[0087] Method 4: The preparation component is Ni 52 Ti 47 Alloy V1 was used as a comparative example. Its preparation process was identical to that of Method 1, except for the vanadium content. Testing showed that this comparative alloy exhibited a room-temperature hyperelastic stress plateau of 450 MPa and a tensile strength of 575 MPa.
[0088] Method 5: Preparation of Ni with near-equal atomic ratio 50.2 Ti 49.8 The alloy used as a comparative example was prepared using the same steps as Method 1, except that vanadium was not added. Testing showed that the room-temperature hyperelastic stress plateau of this comparative alloy was 400 MPa, and its tensile strength was 550 MPa. Compared to Method 1, this invention, by adding vanadium, significantly improved both the stress plateau and tensile strength of the alloy, fully demonstrating the alloying strengthening effect of vanadium.
[0089] Comparing the above adjustment methods, it can be seen that when the alum content is 2-4%, the alloy exhibits better mechanical properties, meaning that the tested material parameters (tensile strength and elongation at break) meet the target performance parameters of the integrated component. For example... Figure 6 As shown, the alloy's material parameters are optimal when the mass content of vanadium is 3%.
[0090] In some embodiments, after adjusting the key component variables and key control variables in the preparation process, and testing material parameters based on the adjusted materials, the method further includes: A material optimization dataset is formed based on the key component variables of the target material system (such as the component contents of nickel (Ni), titanium (Ti), and vanadium (V)) and key control variables in the preparation process (such as temperature and pressure control during the preparation process), as well as the corresponding material parameters after testing (such as the tensile strength and elongation at break of the alloy).
[0091] Based on the materials optimization dataset, using key component variables and key control variables in the preparation process as samples, and corresponding material parameters as labels, a neural network model (e.g., Back Propagation) is trained. After training, a material mapping relationship model between key component variables, key control variables in the preparation process, and material parameters is obtained.
[0092] Based on the material mapping relationship model and material parameters, a multi-objective optimization method can be used to solve the Pareto front, thereby obtaining the key component variables of the material parameters required for different application cases and the key control variables in the preparation process.
[0093] In some embodiments, after determining a customized material that satisfies the material parameters, the method further includes: Finite element analysis software integrating the material constitutive model of the customized material is used to verify the multi-functional coupling performance of the target component corresponding to the structural parameters. The verified parameters obtained from the multi-functional coupling performance verification are then compared with the target performance parameters. Specifically, the multi-functional coupling performance verification can be carried out through a combination of virtual simulation and prototype testing. For example, a comprehensive simulation of the load-bearing and vibration-damping component under target working conditions can be performed, including its overall performance in terms of load-bearing capacity, deformation recovery, energy dissipation, and fatigue life. These parameters are then quantitatively compared with the target performance parameters to verify whether the final design scheme of the target component is qualified.
[0094] If the ratio of the deviation of the comparison result to the target performance parameter is less than or equal to a preset deviation threshold (e.g., 10%), the structural parameters and material parameters of the target component are output.
[0095] In this embodiment, the integrated structural design is simulated and verified by combining customized materials with structural parameters, thereby ensuring that the customized materials can meet the target performance parameters under the current structural design.
[0096] In some embodiments, if the ratio of the deviation of the comparison result to the target performance parameter is greater than a preset deviation threshold, the user's adjustment to the integrated structural design of the target component is received, and the process jumps to execute the step of calling the finite element analysis software that integrates the material constitutive model of the customized material to perform multi-functional coupling performance verification on the target component corresponding to the structural parameters, and comparing the multi-functional coupling performance verification result with the corresponding material parameters, until the deviation of the comparison result is less than or equal to the preset deviation threshold.
[0097] For example, in the design of engine blade structures, if the deviation of the comparison results exceeds a preset deviation threshold, the five-blade design in the engine blade structure can be modified to a six-blade design. As can be seen from Table 4 below, the five blades are radially asymmetrical, and the radial stiffness and axial stiffness are too different. Therefore, the structural design of the target component is improved to a six-blade structure.
[0098] Table 4. Analysis of Customized Materials and Target Performance Parameters under Different Structural Designs
[0099] After adjusting to a six-leaf structure, the process jumps to execute the finite element analysis software that integrates the material constitutive model of the customized material, performs multi-functional coupling performance verification on the target component corresponding to the structural parameters, and compares the verification parameters obtained from the multi-functional coupling performance verification with the target performance parameters until the ratio of the deviation of the comparison result to the target performance parameter is less than or equal to the preset deviation threshold.
[0100] In this embodiment, after customizing the materials, the integrated structural design can be fine-tuned to ensure that the integrated structural design of the fine-tuned structural parameters and the material parameters of the customized materials meets the target performance parameters.
