Description

Technical Field

[0001] This invention relates to the field of turbine engines, and more specifically to a method for designing performance components. Background Technology

[0002] The pre-swirl nozzle is a crucial component of the high-pressure turbine unit in an aero-engine, belonging to the category of large, thin-walled annular parts. Located between the combustion chamber and the high-pressure turbine, the pre-swirl nozzle provides pre-swirled cooling gas to the downstream turbine rotor. As an annular component with inner and outer thin-walled rings, its complex structure and small blade height make it one of the most difficult engine parts to manufacture. Currently, casting is used to manufacture pre-swirl nozzles, but this method suffers from low yield and long production cycles.

[0003] During the design phase of the pre-swirling nozzle, a fluid-structure interaction (FSI) optimization method is employed. This method involves establishing a structural optimization model, an aerodynamic performance optimization model, and an intermediate platform. The intermediate platform serves to transmit the structural model and flow field boundaries. The specific optimization steps are as follows: first, structural optimization is performed, using the optimized structure as input for aerodynamic performance optimization; then, aerodynamic performance optimization is performed, using the optimized flow field boundaries as input for structural optimization, and so on, iterating repeatedly.

[0004] The inventors discovered that the existing technology has at least the following problems: this iterative optimization method requires rebuilding the mesh model for structural and performance analysis for each iteration, resulting in high computational costs and low design efficiency. Summary of the Invention

[0005] This invention proposes a performance component design method to improve the design method of performance components and enhance design accuracy and efficiency.

[0006] This invention provides a performance component design method, comprising the following steps:

[0007] Determine the solid and fluid analysis domains of the performance components;

[0008] A three-dimensional mesh model of the solid analysis domain of the aforementioned performance component is established;

[0009] Based on the three-dimensional mesh model of the solid analysis domain, the three-dimensional mesh model of the fluid analysis domain is obtained;

[0010] Establish the correspondence between the mesh nodes at the interface between the three-dimensional mesh model of the solid analysis domain and the three-dimensional mesh model of the fluid analysis domain;

[0011] The three-dimensional model of the performance component was calculated.

[0012] In some embodiments, before obtaining the three-dimensional model of the performance component, the following steps are further included:

[0013] Based on the weight reduction requirements of the performance component, determine the area to be optimized for the performance component;

[0014] For the area to be optimized, design for material removal or filling is performed.

[0015] In some embodiments, the filling method includes grid filling.

[0016] In some embodiments, before obtaining the three-dimensional model of the performance component, the following steps are further included:

[0017] Based on the stress condition of the performance component, determine the area of ​​the performance component that needs to be strengthened;

[0018] Increase the material thickness of the area to be reinforced.

[0019] In some embodiments, after obtaining the three-dimensional model of the performance component, the following steps are further included:

[0020] Verify whether the three-dimensional model of the performance component meets the process requirements;

[0021] A three-dimensional model of the performance component that meets the process requirements is printed to obtain the performance component.

[0022] In some embodiments, obtaining the three-dimensional mesh model of the fluid analysis domain based on the three-dimensional mesh model of the solid analysis domain includes the following steps:

[0023] Extract the surface mesh of the solid analysis domain at the interface with the fluid analysis domain from the three-dimensional mesh model of the solid analysis domain, and use this surface mesh as a shared mesh;

[0024] A two-dimensional mesh of the fluid analysis domain is established, and the two-dimensional mesh is overlapped with the common mesh nodes to obtain the overall two-dimensional mesh model of the fluid analysis domain;

[0025] Based on the overall two-dimensional mesh model of the fluid analysis domain, the three-dimensional mesh model of the fluid analysis domain is obtained.

[0026] In some embodiments, after establishing the correspondence between the mesh nodes at the boundary between the three-dimensional mesh model of the solid analysis domain and the three-dimensional mesh model of the fluid analysis domain, the following steps are further included:

[0027] Determine the optimization target parameters for the performance component;

[0028] Based on the optimization target parameters, the three-dimensional mesh model of the solid analysis domain and the three-dimensional mesh model of the fluid analysis domain are iteratively optimized.

[0029] In some embodiments, the optimization target parameters include at least one of the following: strength parameters and performance parameters.

[0030] In some embodiments, the performance component includes one of the following: a pre-swirl nozzle, a compressor guide vane, a turbine guide vane, and a fuel nozzle.

[0031] The performance component design method provided by the above technical solution first divides the performance component into a solid analysis domain and a fluid analysis domain based on its characteristics, and then establishes a three-dimensional mesh model for the solid analysis domain. Based on the obtained three-dimensional mesh model of the solid analysis domain, the three-dimensional mesh model of the fluid analysis domain is determined. In determining the three-dimensional mesh model of the fluid analysis domain, the method relies on the parameters in the three-dimensional mesh model of the solid analysis domain. This ensures that the three-dimensional mesh models of the solid and fluid analysis domains are not completely independent, but rather share some identical, one-to-one corresponding mesh nodes at the boundary between the two domains. During subsequent optimization design, these identical mesh nodes consistently maintain the same coordinate parameters. If the coordinate parameters of one of a pair of corresponding nodes change during the design process, the other node in the pair also changes synchronously. In other words, the three-dimensional mesh models of the solid and fluid analysis domains are synchronously linked and can be adjusted synchronously. This design method reduces the number of iterative calculations in the performance component design process, eliminates the need for re-mesh generation in the fluid-structure interaction iteration section, and significantly improves design efficiency.

[0043] The following is combined Figures 1-10 The technical solution provided by this invention will be described in more detail below.

[0044] This invention provides a method for designing a performance component, used to design performance component 1. Performance component 1 includes one of the following: a pre-swirl nozzle, a compressor guide vane, a turbine guide vane, and a fuel nozzle.

[0045] See Figure 1 The design method for this performance component includes the following steps:

[0046] Step S100: Determine the solid analysis domain and fluid analysis domain of performance component 1.

[0047] The solid analysis domain of performance component 1 corresponds to the physical structure of performance component 1. The fluid analysis domain of performance component 1 is the region where the fluid enters performance component 1 or flows through a portion of performance component 1. For example, see the documentation for a pre-swirling nozzle. Figure 2 , Figure 3 and Figure 4 The gas flows into the cavity of the pre-swirling nozzle in the direction indicated by arrow S0. The thin-walled shell of the pre-swirling nozzle corresponds to the solid analysis domain S1; there is a fluid analysis domain S2 at both the inlet and outlet of the pre-swirling nozzle.

[0048] Step S200: Establish a three-dimensional mesh model of the solid analysis domain of performance component 1.

[0049] Once the solid analysis domain of performance component 1 is determined, a three-dimensional mesh model of the solid analysis domain can be established using methods such as finite element analysis.

[0050] Step S300: Obtain the three-dimensional mesh model of the fluid analysis domain based on the three-dimensional mesh model of the solid analysis domain.

[0051] In step S300 above, the three-dimensional mesh model of the fluid analysis domain can be obtained from the three-dimensional mesh model of the solid analysis domain using various methods. Since the parameters used to obtain the three-dimensional mesh model of the fluid analysis domain are the node parameters in the three-dimensional mesh model of the solid analysis domain, the three-dimensional mesh models of the solid and fluid analysis domains are not independent models but are linked at their nodes. This eliminates the need to design additional auxiliary models to establish the three-dimensional mesh models of the fluid and solid analysis domains, making the entire design method more efficient.

[0052] See Figure 5 In some embodiments, step S300 specifically includes the following steps:

[0053] Step S301: Extract the surface mesh of the solid analysis domain from the three-dimensional mesh model of the solid analysis domain and use it as the interface between the solid analysis domain and the fluid analysis domain, and use this surface mesh as the shared mesh;

[0054] Step S302: Establish a two-dimensional mesh for the fluid analysis domain and overlap the two-dimensional mesh with the shared mesh nodes to obtain a closed two-dimensional mesh model of the entire fluid analysis domain.

[0055] See Figure 6 As shown, Figure 6 This is a closed two-dimensional mesh for the obtained fluid analysis domain. Figure 5 In the diagram, the dashed and solid lines together represent the boundaries of the fluid analysis domain of performance component 1. Dashed lines M11, M12, and M13 are the inlet boundaries of the fluid analysis domain. Dashed lines M21, M22, and M23 are the outlet boundaries of the fluid analysis domain. Solid lines M31 and M32 correspond to the shared boundaries of the fluid and solid analysis domains.

[0056] Step S303: Based on the overall two-dimensional mesh model of the fluid analysis domain, obtain the three-dimensional mesh model of the fluid analysis domain. Known techniques can be used to convert the two-dimensional mesh to a three-dimensional mesh model.

[0057] Step S400: Establish the correspondence between the mesh nodes at the interface between the three-dimensional mesh model of the solid analysis domain and the three-dimensional mesh model of the fluid analysis domain.

[0058] The mesh nodes at the interface between the 3D mesh models of the solid and fluid analysis domains are shared nodes, which have the same coordinate parameters in the 3D mesh models. There is a one-to-one correspondence between the mesh nodes at the interface between the 3D mesh models of the solid and fluid analysis domains. For any pair of corresponding mesh nodes, a change in the parameter of one mesh node will synchronously change the parameter of the other mesh node. This change defines the correspondence between the mesh nodes at the interface between the 3D mesh models of the solid and fluid analysis domains.

[0059] Step S500: Design and obtain the three-dimensional model of performance component 1.

[0060] In some embodiments, after step S500, the performance component design method further includes the following steps:

[0061] Step S600: Verify whether the 3D model of performance component 1 meets the process requirements;

[0062] Step S700: Print a three-dimensional model of performance part 1 that meets the process requirements to obtain performance part 1.

[0063] A geometric model of the pre-rotating nozzle, meeting the format requirements of additive manufacturing equipment, was exported and its process verified. Once the process verification met the requirements, the fabrication of performance component 1 was completed, thus completing the entire process from design to manufacturing. The performance component design method provided by the above technical solution can utilize additive manufacturing to address the low yield and long cycle time issues of traditional foundry processing, but it is not limited to additive manufacturing. Using additive manufacturing can broaden the design optimization space, enabling the design of complex structures and local surface improvements for performance component 1. Additive manufacturing technology uses metal powder as raw material, employing laser melting / rapid solidification layer-by-layer deposition for "growth manufacturing," allowing for the one-step creation of fully dense, high-performance titanium alloy structural components from a part CAD model.

[0064] See Figure 7 In some other embodiments, prior to step S300 described above, the performance component design method further includes the following steps:

[0065] Step S210: Based on the weight reduction requirements of performance component 1, determine the optimization area of ​​performance component 1. Topology optimization can be used to design the optimization area. For each performance component 1, the weight reduction can be set according to design requirements. Taking the pre-swirl nozzle as an example, the topology optimization area is selected from the inner mesh of the non-aerodynamic surface. Topology optimization technology refers to finding the optimal material distribution or force transmission path within a given design space, thereby obtaining the lightest design while satisfying various performance requirements.

[0066] Step S220: Design or fill the area to be optimized by removing material. See [link / reference] Figure 8 Region Y1 is the topology optimization region, which is hollowed out. This region is the solid interior of the pre-swirl nozzle; hollowing it out will not significantly affect the strength or aerodynamic performance of the pre-swirl nozzle, and it also allows for weight reduction. If the product weight is too light or the strength decreases after material removal, the empty region can be filled as needed. Mesh filling can be used for this purpose.

[0067] In some embodiments, prior to step S300, the performance component design method further includes the following steps:

[0068] Step S230: Determine the area to be reinforced for performance component 1 based on the stress condition of performance component 1;

[0069] Step S240: Increase the material thickness of the area to be reinforced.

[0070] The execution order of steps S210 and S230 described above is not specified. See also Figure 9 , Figure 9 The diagram illustrates the model after local reinforcement, where the material thickness at the region Y2 to be reinforced is increased, thereby increasing the strength of this region.

[0071] See also Figure 7 After step S400, the performance component design method further includes the following steps:

[0072] S410. Determine the optimization target parameters for performance component 1. Optimization targets may include, for example, the performance, weight, load-bearing capacity, and strength of performance component 1. For the pre-swirl nozzle, the optimization targets are primarily its performance and strength.

[0073] S420. Based on the optimization target parameters, iteratively optimize the three-dimensional mesh model of the solid analysis domain and the three-dimensional mesh model of the fluid analysis domain.

[0074] The above technical solution, after establishing the correspondence between the mesh nodes at the intersection of the three-dimensional mesh model of the solid analysis domain and the three-dimensional mesh model of the fluid analysis domain, performs iterative optimization based on the optimization target parameters. This not only achieves the coupling of the solid analysis domain and the fluid analysis domain of performance component 1, but also eliminates the need to reconstruct the three-dimensional analysis meshes of the fluid analysis domain and the fluid analysis domain during the iteration process. Furthermore, it can generate additional reinforcing structures and low-mass-density grid-filling structures during the optimization process, based on structural strength or weight reduction requirements, to meet the different performance requirements of different regions of performance component 1.

[0075] It is evident that the performance component design method provided by the above technical solution combines the advantages of additive manufacturing processes. Furthermore, it achieves weight reduction and localized reinforcement of performance component 1 during the process, simplifies the iteration process, eliminates the need for repeatedly constructing 3D analysis meshes for both the fluid and solid analysis domains, resulting in high design efficiency. The resulting 3D model structure of performance component 1 is more optimized, leading to a high yield rate in subsequent manufacturing. Additive manufacturing technology represents the development direction of advanced manufacturing technology and has significant advantages in manufacturing complex structural parts. In engine component design, combining additive manufacturing processes and optimization techniques broadens the design space for engine components.

[0076] See Figure 10 The following section uses performance component 1, a pre-swirl nozzle on an aero-engine, as an example to introduce a specific implementation method. The pre-swirl nozzle is part of the engine's air supply system, mainly providing pre-swirl cooling gas to the turbine blades.

[0077] Step S1. Determine the fluid analysis domain and solid analysis domain of the pre-swirling nozzle structure. For example... Figure 4 As shown, the solid analysis domain S1 corresponds to the solid structure of the pre-swirling nozzle. The fluid analysis domain S2 corresponds to the regions where the fluid is located at the inlet and outlet of the pre-swirling nozzle, as well as the region corresponding to the through-hole.

[0078] Step S2. Establish a three-dimensional mesh model of the solid analysis domain. A finite element analysis software can be used to obtain a three-dimensional mesh model of the solid analysis domain. The three-dimensional mesh model includes many mesh nodes, each with relatively defined three-dimensional position parameters.

[0079] Step S3. Extract the surface mesh of the solid mesh at the interface between the solid analysis domain and the fluid analysis domain. Once the 3D mesh model of the solid analysis domain is determined, the coordinates of each mesh node on this 3D mesh model are also determined. Considering the structural characteristics of the pre-swirling nozzle, the wall of the through-hole of the pre-swirling nozzle is the interface between the solid analysis domain and the fluid analysis domain. The mesh nodes on the 3D mesh model of the solid analysis domain corresponding to this interface can be simultaneously used as mesh nodes in the fluid analysis domain. This node is a mesh node on the surface mesh and is a two-dimensional parameter.

[0080] Step S4. Establish surface meshes at the air inlet and outlet of the fluid analysis domain and overlap the nodes with the two-dimensional surface mesh extracted in step S3 of the previous step to form a closed loop, as shown below. Figure 6 As shown. The entire fluid analysis domain S2 comprises three main regions. Step 3 above defines the middle section of the fluid analysis domain S2, plus... Figure 6 The regions corresponding to the inlet and outlet shown form the complete fluid analysis domain S2, i.e. Figure 6 The dashed lines and the area enclosed are shown.

[0081] Step S5. Based on the closed-loop mesh from the previous step, generate a three-dimensional mesh model of the fluid domain. The two-dimensional fluid region obtained in Step 4 is transformed to obtain a three-dimensional mesh model of the fluid domain.

[0082] Step S6. Extract the fluid and solid mesh nodes at the fluid-solid interface and use them as design variables for the fluid and solid domains, respectively (specifically, mesh node coordinates). Establish a synchronization relationship between the mesh nodes of the fluid and solid analysis domains at the interface. Specifically, each mesh node in the fluid analysis domain at the interface corresponds to one of the mesh nodes in the solid analysis domain located at the interface. In subsequent design, if a mesh node in the fluid analysis domain changes, the corresponding node in the solid analysis domain at the same location will also change, and vice versa. This achieves coupling between the fluid and solid analysis domains.

[0083] Step S7. Based on the weight reduction requirements of the pre-swirl nozzle, determine whether topology optimization design is necessary. The area for topology optimization should avoid the main flow channel as much as possible to prevent affecting the flow characteristics of the fluid after entering the pre-swirl nozzle. In some embodiments, the topology optimization region of the pre-swirl nozzle is a non-aerodynamic inner mesh. No fluid flows through this region, so it does not affect the aerodynamic profile of the fluid. If the design requirements of the pre-swirl nozzle determine the weight reduction optimization target and strength requirements, then based on these targets, determine whether to remove material from the optimization region, and whether to fill the removed area. There are various filling methods, such as grid filling, and specifically, rod-shaped or sheet-shaped fillers can be selected.

[0084] Step S8. Based on the stress requirements of the structural components, determine whether it is necessary to improve the local stress concentration or strengthen the local design of the structural components. The design area should avoid the main flow channel as much as possible, that is, select a non-main flow channel area for structural reinforcement to avoid the reinforced structure affecting the flow characteristics. In some embodiments, the corner of the outer surface of the pre-swirl nozzle structure is selected as the area to be optimized, and the node design boundary at the corner is determined. That is, the nodes in this area can be disturbed within a small range within the space defined by the design boundary and the original outer surface of the outer ring to alleviate the stress concentration problem at the corner point.

[0085] Step S9. Set the optimization objectives and boundary parameters (including process boundary parameters) for other optimization parameters in the fluid and solid domains. The optimization objectives and boundary parameters for performance components 1 with different structures are different. Taking a pre-swirling nozzle as an example, its optimization objectives and boundary parameters mainly include performance parameters and strength parameters.

[0086] Step S10. Perform the optimization design of the pre-swirl nozzle structure. This can be repeated iteratively. Figure 10The steps within the dashed box are for achieving optimized design.

[0087] Finally, a pre-rotating nozzle geometric model that meets the format requirements of additive manufacturing equipment is exported, and the process is verified. Finally, the fabrication of the redesigned pre-rotating nozzle model structure is completed.

[0088] The performance component design method provided by the above technical solution, in the design process of performance component 1, establishes a synchronous relationship between the deformation of mesh nodes at the common boundary of the solid domain and the fluid domain, realizing fluid-structure interaction iterative calculation without re-meshing, and simultaneously achieving optimization. Furthermore, it realizes the weight reduction and local reinforcement design of the pre-swirling nozzle, achieving fluid-structure interaction optimization design of the pre-swirling nozzle. The pre-swirling nozzle designed using this method improves the engine's efficiency and economic benefits. Fluid-structure interaction refers to the interaction between a movable or deformable structure and its internal or environmental fluid. Moreover, in the above design process, the aerodynamic performance optimization of the pre-swirling nozzle structure, the optimized design of the pre-swirling nozzle to reduce its weight, and the addition of nodal perturbation design variables to improve the local stress concentration problem of the pre-swirling nozzle structure can all be implemented in parallel to further improve the efficiency of design analysis.
