Description

Technical Field

[0001] The present invention belongs to the field of acoustic material design, and in particular relates to a design method, equipment and medium for an acoustic component. Background Art

[0002] Acoustic components, crucial for acoustic cloaking underwater vehicles, are typically constructed from an elastomeric matrix, often embedded with cavities, metal resonators, or porous structures to enhance sound absorption in specific frequency bands. However, acoustic components operate in the high hydrostatic pressure of the deep sea, where they deform, causing their internal structure to deviate from the optimal shape designed for atmospheric pressure, severely impacting their sound absorption performance. Therefore, it is crucial to accurately derive the geometric structure required for atmospheric pressure manufacturing to ensure that the components achieve the desired target shape after deformation in deep water.

[0003] In existing technologies, topology optimization, shape optimization, and traditional parameter scanning methods are usually used to obtain geometric structures under normal pressure. However, these methods have several drawbacks:

[0004] 1. Topology optimization and shape optimization methods construct objective functions and design variables, perform numerical optimization inversion based on the target geometry, and obtain the original shape under normal pressure. However, there are the following problems:

[0005] ①The amount of calculation is huge and the solution time is long;

[0006] ②The results often have multiple solutions and poor stability;

[0007] ③ The optimization results often produce shapes that are inconsistent with common sense or not conducive to mold processing and manufacturing;

[0008] ④It is difficult to control the geometric characteristics of specific areas.

[0009] 2. The traditional parameter scanning method simulates different primitive geometric shapes by trying them out, applying hydrostatic pressure one by one, and comparing the shapes. However, this method is extremely inefficient and cannot meet the needs of rapid design of complex structures.

[0010] Therefore, there is an urgent need for a design method with a clear physical basis, strong controllability and high computational efficiency to solve the problems of existing methods. Summary of the Invention

[0064] In order to make the purpose, technical solutions and advantages of the present invention more apparent, exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0065] To address the problems of existing methods, such as long solution times, low computational efficiency, and difficulty controlling the geometric characteristics of component regions, the present invention proposes a design method, equipment, and medium for acoustic components. This method performs structural design based on target geometric parameters and applied forces, improving modeling efficiency and significantly enhancing the feasibility of the designed structure. The present invention is further described below in conjunction with the accompanying drawings.

[0066] To facilitate understanding of the present invention, a method for designing an acoustic component disclosed in an embodiment of the present invention is first described in detail. The method for designing an acoustic component provided in an embodiment of the present invention is generally executed by a computer device with certain computing capabilities, such as a terminal device, a server, or other processing device. The terminal device may be a user equipment (UE), a mobile device, a user terminal, or a terminal. In some possible implementations, the method for designing an acoustic component may be implemented by a processor invoking computer-readable instructions stored in a memory.

[0067] The following reference Figure 1 A method for designing an acoustic component according to an embodiment of the present invention will be described.

[0068] like Figure 1 As shown, the design method of the acoustic component in the present invention includes at least the following steps S100 to S300.

[0069] Step S100: Acquire target geometric parameters of the acoustic component in the target application environment.

[0070] Acoustic components are functional components or structures that, through specific design or material combination, can actively or passively control sound propagation and improve the acoustic environment. In the present invention, acoustic components can be cavity-type acoustic components or composite acoustic components containing metal inclusions, localized resonance units, and a rigid core.

[0071] In this invention, the target application environment refers to an environment in which the acoustic component may deform, causing its internal structure to deviate from its optimal design under normal pressure. Specifically, the target application environment is an environment where the acoustic component is subjected to pressures greater than or less than 1 standard atmosphere. Furthermore, temperature, humidity, water flow rate, wind speed, and other environmental factors are not considered in this invention and are therefore not considered in the design of the acoustic component.

[0072] Step S200: Determine the force acting on the acoustic component in the target application environment.

[0073] Specifically, in the present invention, the force acting on the acoustic component can be determined according to the pressure in the target application environment.

[0074] When the target application environment is such that the pressure on the acoustic component is greater than 1 standard atmosphere, the direction of the force is from the outside of the acoustic component to the inside, causing the acoustic component to contract. When the target application environment is such that the pressure on the acoustic component is less than 1 standard atmosphere, the direction of the force is from the inside of the acoustic component to the outside, causing the acoustic component to expand. It will be understood that the magnitude of the force is determined by the magnitude of the pressure.

[0075] Step S300: Calculate and obtain geometric design parameters of the acoustic component based on the target geometric parameters and the acting force.

[0076] Specifically, the method for calculating the geometric design parameters of the acoustic component in the present invention is to apply the reaction force of the action force to the acoustic cavity structure of the acoustic component, perform equivalent inversion, realize structural design, and obtain the geometric design parameters.

[0077] Specifically, when the target application environment is that the pressure on the acoustic component is greater than 1 standard atmospheric pressure, the direction of the reaction force is from the inside of the acoustic component to the outside, causing the acoustic component to expand; when the target application environment is that the pressure on the acoustic component is less than 1 standard atmospheric pressure, the direction of the reaction force is from the outside of the acoustic component to the inside, causing the acoustic component to contract.

[0078] It should be noted that the method of the present invention is not only applicable to acoustic components made of elastomers, such as rubber, thermoplastic elastomers, etc.; it is also applicable to acoustic components made of composite materials with nonlinear deformation capabilities, such as resin-based composite materials and insert structures.

[0079] The present invention provides a simple, efficient, and physically intuitive design method for acoustic components. Structural design is performed based on target geometric parameters and forces, which not only improves modeling efficiency but also significantly enhances the feasibility of the designed structure. The method has a wider scope of application and can cover a variety of material systems and structural forms. The designed structure has high manufacturability and engineering rationality.

[0080] In one embodiment of the present invention, Figure 2 As shown, the method for calculating the geometric design parameters of the acoustic component based on the target geometric parameters and the acting force includes the following steps S301 to S303.

[0081] Step S301: Based on target geometric parameters, an acoustic component model is established through software simulation.

[0082] In this embodiment, existing software may be used for simulation, such as finite element analysis software ABAQUS, finite element analysis software ANSYS, and multi-physics field simulation software COMSOL.

[0083] Step S302: Based on the manufacturing material of the acoustic component and the acting force, a reaction force to be applied to the acoustic component model under normal pressure is generated.

[0084] Specifically, based on the pressure of the action force, the reaction force pressure to be applied to the acoustic component model is determined using a pre-generated functional relationship between the action force pressure and the reaction force pressure of the manufacturing material. Based on the reaction force pressure, the reaction force to be applied to the acoustic component model under normal pressure is generated. It will be understood that the magnitude of the reaction force to be applied to the acoustic component model under normal pressure is determined based on the reaction force pressure, and the direction of the reaction force is opposite to that of the action force.

[0085] Step S303: applying a reaction force to the acoustic component model under normal pressure through software simulation to obtain deformed geometric parameters of the acoustic component model under normal pressure.

[0086] In this embodiment, the simulation method includes but is not limited to finite element numerical analysis method, mathematical analysis method, etc.

[0087] Step S304: Using the deformed geometric parameters as geometric design parameters of the acoustic component.

[0088] The structural reconstruction technology of this embodiment is based on the pressure-deformation equivalence principle and provides an effective tool for the reverse design of acoustic functional structures through the inverse geometric design method, which has important engineering application prospects.

[0089] Next, refer to Figure 3 A method for designing an acoustic component according to an embodiment of the present invention will be described.

[0090] In this embodiment, the target application environment is a deep-sea underwater environment. The force acting on the acoustic component is hydrostatic pressure. Accordingly, the action pressure is hydrostatic pressure, and the reaction pressure is expansion pressure. The acoustic component is made of a composite material with nonlinear deformation capabilities. The steps of this embodiment are described in detail below.

[0091] like Figure 3 As shown, in this embodiment, the design method of the acoustic component includes the following steps S101 to S301.

[0092] Step S110: target structure setting, obtaining target geometric parameters and pressure under deep-sea high hydrostatic pressure environment.

[0093] In this embodiment, the acoustic component is a sound-absorbing component on the outer surface of the underwater vehicle. First, the internal structure of the acoustic component to be achieved in a deep-sea high hydrostatic pressure environment is designed, such as a cavity structure or an inclusion arrangement, to obtain the target geometric parameters.

[0094] Step S210: Equivalent expansion loading.

[0095] Based on the target geometric parameters, an acoustic component model is created through software simulation. In a simulation environment at normal pressure, an equivalent reaction pressure is applied to the cavity of the acoustic component model, causing it to expand, thereby driving the expansion and deformation of the entire acoustic component model.

[0096] Specifically, the expansion pressure corresponding to the reaction pressure is obtained by the relationship function between the hydrostatic pressure and the expansion pressure shown in the following formula (1):

[0097] p hydrostatic =a(p expansion ) b +c (1)

[0098] Among them, p hydrostatic represents the hydrostatic pressure, p expansion represents the expansion pressure, and a, b, and c represent the relationship coefficients respectively.

[0099] In this embodiment, by controlling the expansion loading conditions, the normal pressure geometry can be flexibly adjusted and mapping models of various target shapes can be quickly obtained.

[0100] Step S310: extracting geometric parameters of the expanded model.

[0101] The structural shape and geometric parameters of the expanded model are recorded and used as the geometric design parameters of the acoustic component under normal pressure.

[0102] This embodiment, based on structural reconstruction technology based on the pressure-deformation equivalence principle, provides a reverse geometry design method for acoustic components under hydrostatic pressure. By "equivalently inverting" the compression process of the acoustic cavity structure caused by hydrostatic pressure into an internal expansion process, the reverse derivation of the structural design objectives is achieved. This method not only improves modeling efficiency but also significantly enhances the feasibility of the designed structure. It effectively solves the mapping problem between the acoustic component's normal pressure manufacturing shape and its deep-water deformed shape. Therefore, it can be widely applied to the pre-deformation geometry design of various underwater sound-absorbing structures.

[0103] In one embodiment, the method for generating the relationship function includes:

[0104] Through simulation experiments, the corresponding expansion pressure of the composite material under different hydrostatic pressures is obtained;

[0105] The conversion relationship between the hydrostatic pressure and the expansion pressure to be fitted is obtained by fitting and a relationship function is generated.

[0106] Next, refer to Figure 4 The following describes in detail a method for generating a relationship function in a design method for an acoustic component according to an embodiment of the present invention, using an acoustic component made of a composite material with nonlinear deformation capability as an example.

[0107] like Figure 4 As shown, in this embodiment, the method for generating a relationship function includes the following steps S401 to S406.

[0108] Step S401: Obtain target geometric parameters and net water pressure of the test component in different underwater environments.

[0109] For example, the structure of the test component is a trumpet-shaped acoustic cavity, and the cross section of the unit structure is as follows: Figure 5 As shown, the volume of the cavity is 1.5153×10-6m 3, serving as the target cavity structure under a water pressure of 1.2 MPa (approximately 120 meters underwater). This means the geometry to be solved should achieve this design shape under a net water pressure of 1.2 MPa. Periodic boundary conditions are set in the x and y directions to simulate the periodic arrangement of these units in actual acoustic components.

[0110] Step S402: for each pure water pressure, apply expansion pressures of different pressures to the test component in a normal pressure environment in sequence through simulation to obtain multiple alternative geometric parameters; wherein the different applied pressures belong to a preset pressure range and increase arithmetically.

[0111] The material model uses the Mooney-Rivlin hyperelastic constitutive model. Finite element simulation is used to apply an expansion pressure of 0.1MPa-0.5MPa to the cavity. The changes in characteristic parameters such as the cavity volume are monitored. All geometric results are extracted and saved. Some Mises stress diagrams during the expansion process are shown in the figure. Figure 6 As shown, Figure 6 (a) is the Mises stress diagram at 0.01MPa (gauge pressure), (b) is the Mises stress diagram at 0.1MPa (gauge pressure), (c) is the Mises stress diagram at 0.3MPa (gauge pressure), and (d) is the Mises stress diagram at 0.5MPa (gauge pressure). The change of cavity volume is as follows: Figure 7 As shown, the horizontal axis is the expansion pressure, the unit is MPa; the vertical axis is the real-time volume of the cavity, the unit is cubic meter (m 3 ).

[0112] The structural shape and geometric parameters of the expanded model are recorded and used as the alternative geometric design parameters of the acoustic component under normal pressure.

[0113] Step S403: Based on the multiple candidate geometric parameters, multiple candidate test component models are obtained through simulation.

[0114] All geometric results saved during the expansion process are remodeled to obtain multiple alternative test component models.

[0115] Step S404 : for a plurality of candidate test component models, a corresponding net water pressure is applied to the outer surface of each candidate test component model through simulation to obtain a plurality of deformed candidate test component models.

[0116] In the simulation, a target hydrostatic pressure of 1.2 MPa was applied to the outer surfaces of multiple alternative test component models to perform compression simulation.

[0117] Step S405: Select an alternative test component model whose error with the target structure is less than a preset threshold from the multiple deformed alternative test component models as the target component model, and use the pressure corresponding to the expansion pressure used in the simulation of the target component model as the expansion pressure to be fitted.

[0118] For the trumpet-shaped cavity of this embodiment, five parameters, namely, cavity volume, total thickness of the covering layer, cavity height, cavity bottom position, and bottom diameter, are used to verify whether it is close to the designed shape after compression. Methods for verifying whether it is close to the designed shape include but are not limited to geometric contour comparison method, node error analysis method, volume error method, overall shape similarity index, etc.

[0119] After calculation, it was found that the geometric shape corresponding to the expansion pressure of 0.5 MPa in step S402 is most consistent with the design shape after compression. Table 1 is a comparison table of the geometric parameters after 0.5 MPa compression and the design shape.

[0120] Table 1

[0121]

[0122]

[0123] As shown in Table 1, the average relative error of each key dimensional parameter reaches 1.827%, which is within the engineering allowable range. It can be considered that the cavity shape after compression reaches the designed shape. Figure 8 To compare the shape of the cavity unit of the test component before and after compression with the target design shape, Figure 8 (a) shows the component's initial shape, i.e., the geometry corresponding to an expansion pressure of 0.5 MPa; (b) shows the shape under a water pressure of 1.5 MPa; and (c) shows the target shape. Therefore, the candidate test component model corresponding to an expansion pressure of 0.5 MPa is used as the target component model, and 0.5 MPa is used as the expansion pressure to be fitted.

[0124] Step S406: Obtain the conversion relationship between the hydrostatic pressure and the expansion pressure to be fitted by fitting and generate a relationship function.

[0125] In the present invention, the fitting method can adopt the existing method, which will not be described in detail here.

[0126] It was found in the simulation experiment that the relationship between expansion pressure and hydrostatic pressure is not linear, but is closely related to the nonlinear constitutive properties of the matrix material. The corresponding conversion relationship can be obtained through numerical fitting, and finally the relationship function shown in formula (1) is obtained.

[0127] The method of generating the relationship function in this embodiment utilizes the reversible deformation characteristics of the material, ultimately making the structural deformation path of the acoustic component "controllable and reversible."

[0128] An embodiment of the present application also provides an electronic device, which includes a memory and a processor. The memory stores a computer program run by the processor. When the computer program is run by the processor, the device equipped with the processor executes the acoustic component design method of any of the above embodiments.

[0129] Next, refer to Figure 9 An example electronic device 100 for implementing the method for designing an acoustic member according to an embodiment of the present invention will be described.

The processor 110, the memory 120, and the communication interface 130 can be interconnected and communicated via a communication bus 140 and / or other forms of connection mechanisms (not shown).

[0131] It should be noted that Figure 9 The components and structure of the electronic device 100 shown are merely exemplary and non-limiting. The electronic device may also have other components and structures as needed.

[0132] Optionally, the communication interface 130 may further include a transmitter and / or a receiver.

[0133] The processor 110 may be a microcontroller unit (MCU), a central processing unit (CPU), a digital signal processor (DSP), a single-chip microcomputer, an embedded device, or other forms of processing units with data processing capabilities and / or instruction execution capabilities.

[0134] The memory 120 can be various forms of computer-readable storage media, such as volatile memory and / or non-volatile memory. Volatile memory may include, for example, random access memory (RAM), cache memory, and synchronous dynamic random access memory (SDRAM). Non-volatile memory may include, for example, read-only memory (ROM), a hard disk, and flash memory. One or more computer program instructions may also be stored on the computer-readable storage medium, and the memory 120 may execute the program instructions to implement the acoustic component design method described above in the embodiments of the present invention.
