[0020] The embodiment of the present invention provides a topological design method for a radar array skeleton, including obtaining an array design index of the radar array skeleton, determining a skeleton design index of a skeleton structure of the radar array skeleton according to the array design index; splitting the skeleton structure into multiple unit structures, and converting the skeleton design index into a unit structure design index of multiple unit structures; based on the unit structure design index, using a finite element simulation tool to perform topological optimization on the unit structure; converting the topologically optimized unit structure into a frame structure; using a finite element simulation tool to optimize the size of the frame structure; merging the optimized frame structure into an overall skeleton structure, and obtaining a structural drawing according to the overall skeleton structure.

In addition, the simulation tool is reasonably used, and the finite element method is used to assist the skeleton structure design, accelerate the design iteration, shorten the design cycle and standardize the design process, thereby avoiding the uncertainty caused by the different experience of designers in the design of the radar array skeleton.

[0021] The control method of the embodiment of the present invention is further described below based on the accompanying drawings.

[0022] Reference Figure 1 , Figure 1 A flowchart of a topological design method of a radar array skeleton provided by an embodiment of the present invention, the topological design method of the radar array skeleton includes but is not limited to the following steps: Step S11, obtaining an array design index of the radar array skeleton, and determining a skeleton design index of the skeleton structure of the radar array skeleton according to the array design index; It should be noted that the array design indicators include but are not limited to the number of array elements, array element spacing, array size, array shape, frequency range, gain and radiation pattern, etc. The array design indicators are determined according to the different performance requirements and application scenarios of different radars. The skeleton design indicators of the skeleton structure of the radar array skeleton are determined by obtaining the array design indicators to ensure the reliability and stability of the skeleton structure, meet the rationality and reliability of the skeleton design indicators, and reduce the production cost and manufacturing cycle of the radar array skeleton.

[0023] Step S12, splitting the skeleton structure into a plurality of unit structures, and converting the skeleton design index into the unit structure design index of the plurality of unit structures; It should be noted that since the skeleton structure is usually an array frame similar to a truss structure, the skeleton structure is split into multiple unit structures, and the skeleton design indicators are converted into unit structure design indicators, so as to optimize the unit structure and array the unit structures into an overall skeleton structure, avoiding direct overall optimization of the large radar array skeleton, thereby saving the computing resources of the radar array skeleton.

[0024] Step S13, based on the unit structure design index, using a finite element simulation tool to perform topology optimization on the unit structure; It should be noted that the topological optimization design response of the unit structure is first determined, and the indicators related to the response are determined for the skeleton structure. Then, the geometric constraints are set according to the actual production and installation requirements of the unit structure, so as to perform topological optimization on the unit structure. This allows the design of the unit structure to reduce the weight of the structure and optimize the unit structure while meeting the requirements of strength, stiffness, strain energy, volume and displacement.

[0025] Step S14, converting the topology-optimized unit structure into a frame structure; It should be noted that the unit structure after topology optimization is similar to a frame layout composed of beams. In order to facilitate processing and assembly, the unit structure needs to be converted into a frame structure composed of standard beams. According to the optimized frame structure size, standard parts similar to the frame structure are selected and arranged according to the optimized layout. The unit structure is optimized and converted into a frame structure to remove excess materials in the unit structure, and the material distribution and connection method of the unit structure are optimized to improve the stiffness, strength and durability of the unit structure and improve the overall performance of the frame structure.

[0026] Step S15, using a finite element simulation tool to optimize the size of the frame structure; It should be noted that by using finite element simulation tools, the initial designed skeleton structure is numerically modeled, and the loads and constraints under actual working conditions are applied to perform static and mechanical analyses of the frame structure, thereby optimizing the size of the frame structure. The size optimization can follow the aforementioned design responses and geometric constraints and other conditions to convert the frame structure of approximate standard part sizes into a size range and add design responses.

[0027] Step S16, merging the optimized frame structures into an overall skeleton structure, and obtaining a structural drawing according to the overall skeleton structure.

[0028] It should be noted that the frame structures after topology optimization and size optimization are merged into an overall skeleton structure, and the optimized standard parts are assembled and connected according to the design requirements to form an overall skeleton structure again. The 3D skeleton structure drawings of the reintegrated overall skeleton structure are converted into 2D engineering drawings, so that the radar array skeleton can be processed and manufactured according to the 2D engineering drawings.

[0029] It should be noted that by dividing a large skeleton structure into multiple unit structures, optimizing the unit structures, converting the optimized unit structures into frame structures, and then integrating the frame structures into skeleton structures, the design efficiency of the radar array skeleton can be improved. In addition, by rationally utilizing simulation tools and using finite element methods to assist skeleton structure design, design iterations can be accelerated, the design cycle can be shortened, and the design process can be standardized, thereby avoiding the uncertainty problems caused by different experience of designers in radar array skeleton design. In addition, in one embodiment, referring to Figure 2 and Figure 7 ,exist Figure 1 Step S12 of the illustrated embodiment also includes but is not limited to the following steps: Step S21, obtaining first size information of the skeleton structure, and splitting the skeleton structure into a plurality of unit structures according to the first size information, wherein the first size information includes at least length, height and thickness; Step S22, obtain first quantity information, second quantity information and third quantity information of multiple unit structures, and calculate the outer dimensions of each unit structure based on the first quantity information, the second quantity information and the third quantity information, wherein the first quantity information represents the number of unit structures divided by the skeleton structure in the width direction, the second quantity information represents the number of unit structures divided by the skeleton structure in the height direction, and the third quantity information represents the number of unit structures divided by the skeleton structure in the thickness direction.

[0030] It should be noted that the array design indicators of the radar array skeleton include but are not limited to external dimensions, mounting surface flatness, and overall rigidity. In this embodiment, the radar array skeleton is similar to a rectangular parallelepiped structure. Assuming that the dimensions of the radar array skeleton are width W, height H, and thickness T, the radar array skeleton is divided into n unit structures, then:

[0031] Among them, i is the first quantity information, that is, the number of unit structures divided by the skeleton structure in the width direction, j is the second quantity information, that is, the number of unit structures divided by the skeleton structure in the height direction, and k is the third quantity information, that is, the number of unit structures divided by the skeleton structure in the thickness direction.

[0032] The outer dimensions of each unit structure are calculated according to the first quantity information, the second quantity information and the third quantity information, where the width, height and thickness of the outer dimensions are W / i, H / j and T / k respectively.

[0033] Furthermore, assuming that the flatness of the mounting surface of the radar array skeleton is P, the flatness of the mounting surface of the skeleton structure is P / max(i, j), where "max()" represents the maximum value of the values ​​in the brackets. In addition, the stiffness E of the skeleton structure is consistent with the stiffness of the radar array skeleton.

[0034] In addition, in one embodiment, referring to Figure 3 and Figure 8 ,exist Figure 1 Step S13 of the illustrated embodiment also includes but is not limited to the following steps: Step S31, obtaining topology optimization design responses and geometric constraints of multiple unit structures; Step S32, topology optimization is performed on the unit structure according to the topology optimization design response and the geometric constraints.

[0035] It should be noted that specific topology optimization design responses are defined for multiple unit structures, and the topology optimization design responses include but are not limited to strain energy, volume, mass, displacement and stress, etc. For the skeleton structure, the topology optimization design response includes but is not limited to strain energy, volume restriction and displacement, etc. The design response results of each unit structure under different conditions are obtained through finite element simulation tools; the geometric constraints of multiple unit structures include but are not limited to axisymmetry, cyclic array or restrictions on the size of the unit structure; based on different topology optimization design responses and set constraints, a variety of different topology optimization schemes can be obtained to optimize the unit structure, and on the premise of ensuring the structural strength and stiffness of the unit structure, the material usage of the unit structure is minimized, the weight of the unit structure is reduced, material costs and energy consumption are reduced, and the efficiency of radar array skeleton design is improved.

[0036] Furthermore, the design response includes at least one of minimum strain energy, volume restriction and displacement, and the geometric constraint includes at least one of axisymmetry, cyclic array and restriction on the size of the skeleton structure. It should be noted that by taking the minimum strain energy as the design response, the distribution of materials in the unit structure is optimized to reduce the total strain energy of the unit structure when loaded after being arrayed into the radar array skeleton, thereby improving the performance and durability of the radar array skeleton. The volume restriction is used to control the overall volume of the radar array skeleton to ensure the stiffness of the optimized unit structure within a certain volume. The displacement is used to improve the stiffness and stability of the unit structure. By reducing the displacement of the unit structure, the deflection of the unit structure is reduced, thereby improving the stability of the radar array skeleton. The axisymmetric constraint can help maintain the axisymmetry of the unit structure, help simplify manufacturing and improve the stability of the unit structure. The cyclic array constraint is suitable for designing a unit structure with periodicity, helping to optimize the material distribution and shape of the periodic unit structure. Limiting the size of the skeleton structure can control the overall size and shape of the structure, ensuring that the final optimized unit structure meets the actual design requirements and constraints.

[0037] In addition, in one embodiment, referring to Figure 4 and Fig. 9 ,exist Figure 1 Step S15 of the illustrated embodiment also includes but is not limited to the following steps: Step S41, obtaining a standard component structure of a frame structure, and obtaining type information of the standard component structure; Step S42, when the type information is more than one, obtaining second size information of the standard part structure, converting the second size information into a size threshold of the standard part structure, so that the standard part structure is added to the design response according to the size threshold; Step S43, when the standard component structure with the design response added meets the unit structure design index, a unique optimization result of the frame structure is obtained; Step S44, arraying the frame structure into an overall skeleton structure according to the unique optimization result.

[0038] It should be noted that, in the process of selecting standard parts, when there is more than one type of standard parts, it is necessary to optimize the size of the frame structure to further determine the size of the standard parts. In this embodiment, the second size information is the size information of the frame structure. When optimizing the size of the frame structure, the aforementioned design response and geometric constraints and other conditions can be used to determine the standard parts structure. When the standard parts structure meets the unit structure design indicators, a unique optimization result of the frame structure is obtained. According to the unique optimization result, the optimized frame structure is arrayed according to the design requirements, thereby forming a radar array skeleton and improving the design efficiency and reliability of the radar array skeleton.

[0039] In addition, in one embodiment, referring to Figure 5 ,exist Figure 1 After step S15 in the illustrated embodiment, the following steps are also included but not limited to: Step S51, performing simulation calculation on the overall skeleton structure to obtain simulation calculation results; Step S52, when the simulation calculation results do not meet the skeleton design indicators, the overall skeleton structure is split into multiple unit structures again, and the process returns to the step of splitting the skeleton structure into multiple unit structures and converting the skeleton design indicators into unit structure design indicators of the multiple unit structures, and iterates again to make the simulation calculation results after the iteration meet the skeleton design indicators.

[0040] It should be noted that the optimized frame structure is arrayed into an overall skeleton structure, and the skeleton structure is simulated and calculated to determine whether the skeleton structure meets the skeleton design index. When the skeleton structure does not meet the index, it returns to step S12 for iteration, so that the iterative simulation calculation structure meets the skeleton design index. By simulating and verifying the overall skeleton structure, it is timely discovered that the performance of the skeleton structure does not meet the skeleton design index, which provides a guarantee for the subsequent optimization of the skeleton structure. The overall skeleton structure is split into multiple unit structures, and specific parts are adjusted and optimized in a targeted manner to further improve the adaptability and performance of the unit structure. The skeleton design index is converted into the design index of the unit structure, and the tasks and performance requirements of each unit structure are clarified to ensure that the overall structure meets the comprehensive performance requirements of the radar array skeleton. Through the process of iterative optimization, each unit structure is gradually improved, and finally an overall structure that meets the skeleton design index is obtained, thereby improving the stability and reliability of the radar array skeleton.

[0041] In addition, in one embodiment, referring to Figure 6 ,exist Figure 1 After step S16 in the illustrated embodiment, the following steps are also included but not limited to: Step S61, obtaining stiffness information, strength information and flatness information of the overall skeleton structure; Step S62, performing static calculation on the overall skeleton structure according to the stiffness information, the strength information and the flatness information to obtain a static calculation result of the overall skeleton structure; Step S63, when the static calculation results meet the array design index, the overall skeleton structure is converted into a structural drawing.

[0042] It should be noted that by performing static calculations on the overall skeleton structure under working loads, it is confirmed that the strength, stiffness and flatness of the overall skeleton structure meet the array design indicators. By obtaining stiffness information, strength information and flatness information and performing static calculations, the force performance of the overall skeleton structure can be comprehensively evaluated, including information on stiffness, strength and flatness. When the static calculation results meet the array design indicators, it indicates that the overall skeleton structure meets the array design indicator requirements under stress, has sufficient bearing capacity and stability, and can be used as a safe and reliable structure for subsequent construction and use. Converting the overall skeleton structure into a structural drawing can convert a 3D stereoscopic drawing into a specific 2D construction drawing, further improving the design and construction efficiency of the radar array skeleton.
