[0002] With the rapid development of modern industry and the continuous improvement of people's living standards, cars have become an indispensable means of transportation in daily life. As an important part of the car, the front hood of the car not only protects the engine, reduces wind resistance, and improves the appearance of the vehicle, but is also directly related to the overall design and manufacturing cost of the car.

[0003] At present, the front hood is usually considered as a whole during the design process. For example, the designer needs to draw an overall sketch of the front hood according to the overall design style and functional requirements of the car, and then use computer-aided design (CAD) software to refine the various components of the front hood, and finally obtain the front hood data model from the overall sketch. The entire design cycle is relatively long.

[0004] However, on family-based cars or family-based front hoods, different family-based front hoods have high similarities. Even if the currently designed family-based front hood has high similarities with the family-based front hoods of the same family, the currently designed family-based front hood still needs to be redesigned as a whole, so it takes a long time to design the desired family-based front hood. Summary of the invention

[0018] A combination module, used to combine multiple local data models that meet the design requirements to obtain at least one family-based front hood data model;

[0019] A selection module is used to select the family front hood data model with the best performance as the family front hood data model designed this time.

[0020] The fifth aspect of an embodiment of the present application provides an electronic device, comprising a memory, a processor, and a computer program stored on the memory and executable on the processor, wherein when the processor executes the computer program, the method for generating a family front hood design as described in the first aspect or the method for selecting a family front hood design as described in the second aspect is implemented.

[0043] Overview

[0044] like Figure 1 As shown, the overall structure of the front hood is very complex, and it is not formed by simple stamping. Moreover, for the sake of automobile safety, the front hood is also required to have certain safety performance. Therefore, the front hood is usually assembled or used as an integral component in the vehicle. As also described in the background technology, the front hood is usually considered as a whole during the design process. Designers continuously adjust the overall design of the front hood based on their own experience, and continuously verify the designed front hood data model, and finally generate a front hood data model that meets the design requirements or business requirements. Subsequent production links will be produced based on the final front hood data model.

[0045] For the front hood of a family car or a family front hood, each family front hood has the same design style and has a high degree of similarity. When a new design is made for the family front hood, even if the new design has a high degree of similarity with the existing design in the family, the new design still needs to be considered as a whole, which inevitably leads to the problem of a long design cycle.

[0046] In response to the above problems, the inventor of the present application has taken a different approach and decomposed the family-based front hood into multiple modules. When designing the family-based front hood, the family-based front hood data model is directly generated by using the module splicing / combination method. Therefore, the embodiment of the present application provides a method for generating a family-based front hood design, the purpose of which is that when designing a family-based front hood, the user or designer can directly select the required object from multiple existing local data models of the family-based front hood. Then the family-based front hood data model can be quickly obtained by combination. Compared with the method of modeling and designing the family-based front hood as a whole, the embodiment of the present application is undoubtedly more convenient and faster, and greatly shortens the design cycle of the family-based front hood. In addition, the target information based on which the family-based front hood is divided into components includes different constraints on the design of the family-based front hood. Therefore, the division of each component is very reasonable, and a reasonable balance can be achieved between the number of components and the difficulty of modeling the local data model. The specific scheme is described in detail below through an embodiment.

[0047] Exemplary Methods

[0048] The embodiment of the present application exemplifies the method for generating a family-based front hood design. Figure 2 As shown, the method for generating a family-based front hood design includes:

[0049] S201: Determine multiple local data models that meet the current design requirements.

[0050] It is understandable that the family-based front hood includes a front hood with a similar design. In the automotive field, some specific components of some vehicles have the same design style or a high degree of similarity, and such designs can be referred to as family-based designs. For example, for a family-based front hood, a family-based front hood with the same design style or a high degree of similarity is installed on different vehicles, and these vehicles or these family-based front hoods can be referred to as family-based designs. That is, these family-based front hoods with the same design style or a high degree of similarity are regarded as different members of a family, and each member has the same design style or a high degree of similarity with other members. In this way, when a front hood design is generated for a family-based front hood, the family-based front hood design to be generated will be a new family member and have a high degree of similarity with other members in the family. In some embodiments, based on the common features of the family-based front hood, a partial local data model matching it can be determined; then, by using the overlap relationship between different local data models, other partial local data models that can be overlapped with the aforementioned partial local data models are determined. Finally, the local data models determined twice are regarded as multiple local data models that meet the design requirements of this time. Among them, the common features of the family-based front hoods can be the same design style information or the same part of the structural information of each member in the family of the family-based front hoods. For example, the common features of the family-based front hoods can be the same outer contour, the same overall design style, etc. The multiple local data models determined in this way will belong to the same family of family-based front hoods, that is, multiple local data models that meet the design requirements of this time, avoiding interference from local data models in other families of family-based front hoods.

[0051] The multiple local data models include: data models of different components into which the family-based front hood is divided based on the target information. In some embodiments, the multiple local data models include at least one data model of each component. For example, the components of the family-based front hood include component A, component B and component C. Then the multiple local data models include: a data model of at least one component A, a data model of at least one component B, and a data model of at least one component C. In the case where the multiple local data models include multiple data models of each component, the multiple data models of each component may not be completely different. For example, different designers can collaborate to create different designs and modeling for the same component to obtain multiple data models of the same component. For example, the data model of the component can also be stored in the library each time the family-based front hood is designed, so as to obtain a model library containing multiple data models of the same component. Of course, the model library can contain data models of the family-based front hood components of multiple families. In this way, no matter which family the new design belongs to, it is only necessary to filter out the data model of the family-based front hood component of the current family.

[0052] In the embodiment of the present application, multiple local data models are generated by pre-modeling. The timing of generating the local data models can be as described above and is not limited here. It is worth noting that the data model of the component can be a conceptual model. For example, the conceptual model can be a shell unit model generated by SFE software. The data model of the component can also be an engineering model. Thus, it is applied to the case where there is a specific design scheme for the family-based front hood. For example, the engineering model can be a 3D model generated by CATIA software.

[0053] In some embodiments, multiple local data models that meet the design requirements can also be determined in combination with the designer's operation. For example, the designer can refer to the same structure of the family front hood for the first input, so that multiple local data models that meet the design requirements can be selected from the aforementioned model library. The first input may include operations such as click, long press, and slide, but is not limited to this. The first input may also include a series of identical or different operations. For example, the first input includes: multiple clicks on different controls. In some embodiments, before responding to the user's first input, a target interface may also be displayed, which includes multiple controls, and each control is associated with multiple data models of a component. In this way, the user can operate each control in turn, thereby selecting one or more data models for each component, and finally obtaining multiple local data models that meet the design requirements. In other embodiments, the target interface displays the data model of the corresponding component and / or the text introduction of the data model for each control. This makes it convenient for users to understand the situation of each data model and provides convenience for users to select local data models.

[0054] As an important part of the car, the family front hood itself can be decomposed into different components. And the components obtained are different according to different decomposition bases. If decomposed from the perspective of quantity, the family front hood can be decomposed into a large number of components, so that the structure of each component will be relatively simple, which is convenient for modeling. However, the family front hood has too many components, which is not only prone to problems in the subsequent layout data model combination; at the same time, it takes users / designers more time and energy to make choices. Of course, if the family front hood is decomposed into fewer components. For example, the family front hood is decomposed into two components. The structure of each component is still very complex, and the modeling process is still complex and time-consuming. For this reason, when the embodiment of the present application decomposes the family front hood into different components, the target information based on it includes: different design constraints of the family front hood. In this way, the division of each component can be made very reasonable by decomposing the family front hood through constraints. Among them, the design constraints may include: constraints related to the structure of the family front hood itself.

[0055] S202: Combine multiple local data models that meet the current design requirements to obtain at least one family-based front hood data model.

[0056] In this step, a plurality of local data models that meet the design requirements can be combined using established combination rules. For example, the combination rules include: selecting one from the local data models of each component of the family-based front hood, respectively, and combining the selected local data models to obtain a combination result. Each combination method or each combination result corresponds to a family-based front hood data model, so that at least one family-based front hood data model can be obtained. In some embodiments, after obtaining the family-based front hood data model, a 3D image of the family-based front hood data model can also be displayed for relevant personnel to view.

[0057] In the embodiment of the present application, multiple local data models that meet the design requirements can be determined. Among them, the multiple local data models include: data models of different components divided into the family-based front hood based on target information, and the family-based front hood includes a family-based front hood with a similar design. Therefore, when designing a family-based front hood, the user or designer can directly select the required object from the multiple local data models of the existing family-based front hood. Then the family-based front hood data model can be quickly obtained by combination. Compared with the method of modeling and designing the family-based front hood as a whole, the embodiment of the present application is undoubtedly more convenient and faster, and greatly shortens the design cycle of the family-based front hood. In addition, the target information based on which the family-based front hood is divided into components includes different design constraints on the family-based front hood. Therefore, the division of each component is very reasonable, and a reasonable balance can be achieved between the number of components and the modeling difficulty of the local data model.

[0058] In some embodiments of the present application, determining a local data model that meets the current design requirements includes:

[0059] Based on the exterior shape information and / or main section information of the family-based front hood, a first type of local data model is determined; wherein the first type of local data model includes: a local data model having the same exterior shape information and / or the same main section information as the family-based front hood;

[0060] determining a second type of local data model that is compatible with the first type of local data model;

[0061] The first type of local data model and the second type of local data model are determined as local data models that meet the current design requirements.

[0062] It should be noted that the same design style or common features in the family-based front hood are usually reflected in the appearance and main section of the family-based front hood. Therefore, the outer shape information and / or main section information of the family-based front hood can be used as the common features of the family-based front hood. In some embodiments, the outer shape and main section of the family-based front hood design to be generated can be determined at the beginning of the design (for example, it can be a design sketch containing only the outer shape and the main section). Then use these data to determine the local data model that meets the design requirements of this time. For example, when generating the family-based front hood design of family A, the outer shape information and main section information of the family-based front hood in family A can be matched to the outer panel data model and the inner panel data model of family A, and then the overlap relationship between the components of the family-based front hood is used to obtain other local data models that are compatible with the outer panel data model and the inner panel data model, and finally these data models are used as local data models that meet the design requirements of this time. Among them, the outer panel data model and the inner panel data model are equivalent to the local data model of the first type. Other local data models adapted to the outer panel data model and the inner panel data model are equivalent to the second type of local data models.

[0063] In the embodiment of the present application, with the aid of the same exterior styling information and main cross-section information in the family-based front hood, the local data models in the same family can be quickly determined, thereby obtaining a local data model that meets the current design requirements.

[0064] In some embodiments of the present application, different design constraints on the family-style front hood include: exterior styling constraints, layout space constraints, dent resistance constraints, pedestrian head impact performance constraints, and pattern stamping process constraints.

[0065] It should be noted that the exterior styling constraints determine the appearance of the family-style front hood, including its coordination with the overall style of the car and its aesthetics. In addition, the exterior styling needs to comply with aerodynamic principles and reduce wind resistance, while also considering the aesthetic needs and design trends of consumers in the market.

[0066] The layout space constraints involve the relative position of the front hood and the components in the engine compartment. It is necessary to ensure that there is enough space between the front hood and these components to avoid interference. At the same time, it is also necessary to consider the convenience of maintenance and the replaceability of components.

[0067] Dent resistance refers to the ability of the front hood to resist deformation and dents when subjected to external forces. This is related to the material selection and structural design of the front hood, and it is necessary to ensure that the structure remains intact and the appearance is smooth under the action of external forces. When designing, it is necessary to consider the various external forces that the vehicle may encounter during driving, and ensure that the front hood has sufficient strength and rigidity to resist these forces. The dent resistance constraint is the constraint generated based on the dent resistance.

[0068] Regarding the constraints on pedestrian head impact performance, this is an important consideration from a safety perspective. The family-style front hood needs to be able to effectively reduce the impact force on the pedestrian's head and reduce damage in the event of a collision. It is also necessary to consider the use of specific materials and structural designs.

[0069] Pattern stamping process constraints: This involves the manufacturing process of the family-style front hood, especially the design constraints imposed by the stamping process. Pattern stamping is to achieve the specific appearance and structural features of the family-style front hood, but overly complex designs may be difficult to achieve through stamping, or may increase manufacturing costs and time.

[0070] The embodiment of the present application starts from all or part of the above constraints and decomposes the family-based front hood to obtain corresponding components. In this way, the family-based front hood obtained by the method provided by the present application can meet the relevant constraints in terms of appearance and performance.

[0071] In some embodiments of the present application, the family-based front hood is divided into different components based on target information, including:

[0072] The outer panel is divided from the family-style front hood based on the external styling constraints;

[0073] The inner panel is divided from the family-style front hood based on the layout space constraints;

[0074] A reinforcement piece divided from the family-style front hood based on the constraints of dent resistance and pedestrian head impact performance;

[0075] The inner panel pattern is divided from the family-style front hood based on the constraints of dent resistance performance, pedestrian head impact performance and pattern stamping process.

[0076] It should be noted that when the car is in normal driving or parking, the part of the family-style front hood that the user can see can be regarded as the appearance part of the family-style front hood, and the appearance part needs to comply with the external shape constraints. Therefore, this part can be classified as the outer panel. Figure 3 As shown, the outer panel 301 shows the appearance of a family-style front hood.

[0077] The side of the front hood opposite to the outer panel faces the engine compartment of the car, and the internal structure of the engine compartment is usually more complicated, so this part of the front hood needs to be reasonably matched with the engine compartment to avoid interference. Therefore, this part (the side of the front hood opposite to the outer panel) can be divided into the inner panel. In some embodiments, the inner panel is constrained by the layout information, and the main section needs to be consistent. And it can be used as a variety of solutions according to the different sealing surfaces and support forms. Figure 4 and Figure 5 As shown, the inner panel 401 may have different structures / schemes.

[0078] The inner and outer panels of the front hood of a family usually need to be filled with some structure to improve the dent resistance and pedestrian head impact performance. Therefore, the structure between the inner and outer panels can be divided into reinforcements. In some embodiments, the reinforcements can include reinforcement plates and support plates between the inner and outer panels. The design of the reinforcement is related to the structure of the inner and outer panels and is not fixed. For example Figure 6 and Figure 7 As shown, the number and specific structure of the reinforcement 601 are not fixed. In some embodiments, when the inner panel structure is relatively flat, more reinforcements are required between the inner and outer panels. They can be support panels on the front, rear, and side surfaces, front door lock reinforcements, and rear hinge reinforcements. In other embodiments, the inner panel structure has a large stamping depth, part of the inner panel and the outer panel serve as a supporting structure, there are fewer internal reinforcements and support members, and the reinforcements may only be front door lock reinforcements and rear hinge reinforcements.

[0079] The design of the inner panel pattern mainly considers two aspects: one is that the performance (anti-dent performance and pedestrian head impact performance) meets the standards, and the other is that the stamping process is feasible. Some more complex shapes and forming angles cannot be achieved by the stamping process, and even if the performance meets the standards, it is impossible to manufacture the actual product. Therefore, the inner panel pattern is considered as a component alone. Figure 8 As shown, twelve different flower types are illustrated.

[0080] In the embodiment of the present application, the family-style front hood can be divided into an inner panel, an outer panel, a reinforcement and a pattern according to different constraints.

[0081] In some embodiments of the present application, the target information also includes: the physical connection relationship inside the family-based front hood. Among them, the inside of the family-based front hood can be understood as the overall structure of the family-based front hood. It is understandable that the family-based front hood is usually not formed in one piece, and its various parts are connected by physical connection to form a whole. Therefore, the family-based front hood can be divided based on the physical connection relationship. In some embodiments, the different components into which the family-based front hood is divided based on the target information include any of the following:

[0082] Outer panels, inner panels with flower patterns, and reinforcements;

[0083] Outer panels, inner panels with reinforcements, and inner panel patterns;

[0084] Outer panels, inner panels, inner panel patterns, front reinforcements, rear reinforcements and side reinforcements.

[0085] Among them, some physical inner panels contain patterns, so the inner panel and the inner panel pattern can be combined into one component. Fig. 9 As shown, twelve different ways of combining the flower pattern with the inner panel are illustrated. At this time, the components of the family-style front hood include: an outer panel, an inner panel with a flower pattern, and a reinforcement.

[0086] The inner panel and the reinforcement of some real family-based front hoods are physically connected, so the inner panel and the reinforcement can be combined into one component. In this case, the components of the family-based front hood include: an outer panel, an inner panel with reinforcements, and an inner panel pattern.

[0087] Similarly, the reinforcements can be subdivided into front reinforcements, rear reinforcements, and side reinforcements. At this time, the components of the family-style front hood include: outer panel, inner panel, inner panel pattern, front reinforcement, rear reinforcement, and side reinforcement.

[0088] In the embodiment of the present application, the components can be divided according to the physical connection relationship between the components in the family front hood.

[0089] According to another aspect of the present application, the present application embodiment also provides a method for selecting a family-style front hood design. Fig.10 As shown, the method for selecting a family-style front hood design includes:

[0090] S1001: Determine multiple local data models that meet the requirements of this design.

[0091] The plurality of local data models include: data models of different components into which the family front hood is divided based on target information, the target information including: different design constraints of the family front hood; the family front hood includes family front hoods with similar designs;

[0092] S1002: combining multiple local data models that meet the current design requirements to obtain at least one family-based front hood data model;

[0093] S1003: Selecting the family-based front hood data model with the best performance as the family-based front hood data model designed this time.

[0094] It should be noted that for steps S1001 to S1002, see Figure 2The relevant contents of S201 to S202 shown are not repeated here. In this embodiment, after obtaining at least one family-based front hood data model, if the number of the family-based front hood data models is multiple, it is necessary to select one of them as the family-based front hood data model designed this time. Among them, the selection basis may include the performance of each family-based front hood data model. The performance here can be understood as the performance of the family-based front hood data model applied to the vehicle. If the performance of a family-based front hood data model is the best, it means that the family-based front hood produced according to it is most suitable for application to the vehicle.

[0095] In the embodiment of the present application, multiple local data models that meet the design requirements can be determined. Among them, the multiple local data models include: data models of different components divided into the family front hood based on the target information, and the family front hood includes a family front hood with a similar design. Therefore, when designing the family front hood, the user or designer can directly select the required object from the multiple local data models of the existing family front hood. Then the family front hood data model can be quickly obtained by combination. Finally, the one with the best performance is selected as the family front hood data model designed this time. Compared with the method of modeling and designing the family front hood as a whole, the embodiment of the present application is undoubtedly more convenient and faster, greatly shortening the design cycle of the family front hood, and can quickly select the best family front hood data model. In addition, the target information based on which the family front hood is divided into components includes different constraints on the design of the family front hood.

[0110] For the relevant contents of the embodiments of the present application, please refer to the corresponding contents in the above-mentioned method embodiment of generating a family-style front hood design, which will not be repeated here.

[0111] In some embodiments of the present application, when there are multiple family-based front hood data models, the family-based front hood data model with the best performance is selected as the family-based front hood data model designed this time, including:

[0112] Simulate each family front hood data model separately to obtain the simulation results of each family front hood data model; determine the family front hood data model with the best simulation results based on the simulation results of each family front hood data model; select the family front hood data model with the best simulation results as the family front hood data model designed this time.

[0113] It should be noted that, when the optimal design is the goal, it is necessary to select the optimal family-based front hood data model from multiple family-based front hood data models and use it as the family-based front hood data model designed this time. In the embodiment of the present application, each family-based front hood data model is simulated in the form of simulation, and then the simulation results are used to compare the advantages and disadvantages of each family-based front hood data model, and finally the optimal family-based front hood data model is determined.

[0114] In some embodiments, a CAE simulation analysis scheme may be used to simulate each family front hood data model and obtain simulation results. The simulation analysis scheme may include at least four aspects of simulation analysis, namely modal analysis, collision safety analysis, stiffness analysis, and structural durability analysis. The simulation results represent the performance of the family front hood data model in each simulation analysis scheme. By comparing the simulation results, the advantages and disadvantages of the family front hood data models can be judged.

[0115] In some embodiments, all possible combinations can be determined based on the specific circumstances of the local data model, and then multiple family-based front hood data models can be obtained based on the determined combinations. For example, the local data model includes: two data models of component A of the family-based front hood, three data models of component B of the family-based front hood, and five data models of component C of the family-based front hood. Then the number of all possible combinations = 2*3*5=30. The local data models can be combined according to these 30 combinations to obtain 30 family-based front hood data models. In some embodiments, before generating the family-based front hood data model, the numbering information of the corresponding data model can be displayed for each component. Fig.11 As shown, in the case where the family-style front hood includes: an outer panel, an inner panel, a reinforcement and an inner panel pattern, the corresponding data model number is displayed in the second area 1102 corresponding to each component in the first area 1101, and preferably, a 3D image of the corresponding data model can also be displayed.

[0116] In the embodiment of the present application, simulation technology can be used to select a family-based front hood data model with the best simulation results as the family-based front hood data model designed this time, so that a more optimized family-based front hood data model can be obtained.

[0117] In some embodiments of the present application, based on the simulation results of each family-based front hood data model, determining the family-based front hood data model with the best simulation result includes:

[0118] Based on the simulation results of each family front hood data model and the preset weights of different simulation dimensions, the design score of each family front hood data model is calculated; the family front hood data model with the largest design score is determined as the family front hood data model with the best simulation result.

[0119] It should be noted that when simulating the family front hood data model, simulation can be performed from different simulation dimensions. This simulation dimension is equivalent to the aforementioned simulation analysis scheme, namely modal analysis, collision safety analysis, stiffness analysis and structural durability analysis. The corresponding simulation results are obtained for each simulation dimension. For example, the simulation dimensions include: modal analysis, collision safety analysis, stiffness analysis and structural durability analysis. Then the simulation results of the family front hood data model include four simulation results, and each simulation dimension corresponds to each simulation dimension. Since the importance of each simulation dimension in the design of the family front hood is different, a weight can be assigned to each simulation dimension in advance. The importance of the corresponding simulation dimension is represented by the weight. Then, when determining the optimal family front hood data model, the simulation results and weights are used for calculation to obtain a design score that measures the excellence / optimization degree of the family front hood data model. The higher the design score, the better. Among them, the family front hood data model with the largest design score can be regarded as the family front hood data model with the best simulation result. There is no limitation here on the numerical relationship between the weights of different simulation dimensions.

[0120] For example, the weights of the four simulation dimensions of modal analysis, collision safety analysis, stiffness analysis, and structural durability analysis are 0.2, 0.4, 0.2, and 0.2, respectively. Assume that the simulation results are represented by normalized scores, and the simulation results corresponding to the simulation dimensions of a family-based front hood data model are 8, 6, 10, and 9, respectively. Then the design score of the family-based front hood data model = 0.2*8+0.4*6+0.2*10+0.2*9=7.8.

[0121] In the embodiment of the present application, the weights of different simulation dimensions can be used to calculate a design score for measuring the degree of optimization of the family-based front hood data model, and then the optimal family-based front hood data model can be determined based on the design score.

[0122] In some embodiments of the present application, when there are multiple family-based front hood data models, the family-based front hood data model with the best performance is selected as the family-based front hood data model designed this time, including:

[0123] Simulate each family front hood data model separately to obtain the simulation result of each family front hood data model; based on the simulation results of each family front hood data model, determine the family front hood data model with the best simulation result as the target combination data model; according to the target fine-tuning rule, fine-tune the local data model in the target combination data model to generate multiple alternative combination data models; simulate each alternative combination data model separately to obtain the simulation result of each alternative combination data model; select the data model with the best simulation result among the multiple alternative combination data models and the target combination data model as the family front hood data model designed this time.

[0124] It should be noted that the family-based front hood data model with the best simulation result can be the family-based front hood data model with the largest design score determined by comparing the design scores in the above embodiment, but is not limited thereto. Any comparison rule can be used to compare the simulation results of each family-based front hood data model to determine the family-based front hood data model with the best simulation result.

[0125] The target fine-tuning rule can be a pre-established rule for adjusting any one or more data models in the target combination data model, and the adjustment scale is small. Therefore, the adjusted multiple candidate combination data models have a high degree of similarity with the target combination data model. In the field of family front hood design, some minor adjustments may greatly improve the optimization degree of the family front hood. Therefore, this embodiment searches for a data model that is better than the target combination data model by fine-tuning.

[0126] The simulation process of the candidate combination data model is the same as the simulation process of the family front hood data model in the above embodiment, and will not be repeated here. In addition, the process of determining the data model with the best simulation result from multiple candidate combination data models and the target combination data model is similar to the process of determining the data model with the best simulation result by comparing the simulation results in the above embodiment, and will not be repeated here.

[0127] In the embodiment of the present application, by fine-tuning the target combination data model, an attempt can be made to find a more optimal data model as the family-based front hood data model.

[0128] In order to avoid interference between the parts in the family front hood data model and thus affect the simulation results, in some embodiments of the present application, each family front hood data model is simulated separately. Before obtaining the simulation results of each family front hood data model, the method further includes:

[0129] Display a three-dimensional image of any family-based front hood data model; adjust the position and / or size of the family-based front hood components in the three-dimensional image in response to a first input from a user; and make corresponding adjustments to the family-based front hood data model corresponding to the three-dimensional image based on changes before and after the three-dimensional image is adjusted.

[0130] It should be noted that for the currently displayed three-dimensional image, there is a corresponding family-based front hood data model. When the three-dimensional image changes, the corresponding family-based front hood data model will change accordingly to ensure the adaptation of the two.

[0131] It is understandable that when the image of a component in a three-dimensional image interferes with the images of other components, it will inevitably affect the subsequent simulation process. Moreover, in the process of designing a family-based front hood, a family-based front hood with interference is generally not designed. Therefore, the aforementioned interference needs to be eliminated. In this embodiment, the first input includes operations such as clicking, sliding, and long pressing, and may also include a series of operations. The user can directly operate the three-dimensional image, and by adjusting the position and / or size of the selected component, most of the interference can be basically eliminated. At the same time, the way of directly operating the image also greatly facilitates user operation.

[0132] In some embodiments, the three-dimensional image of each family-based front hood data model may be displayed in sequence, so that the user can adjust the family-based front hood data model in which interference or other problems occur. In other embodiments, the user may independently trigger the three-dimensional image to be displayed. For example, in response to the user's second input, the three-dimensional image of the family-based front hood data model selected by the user may be displayed.

[0133] In the embodiment of the present application, the user can directly operate the three-dimensional image, and by adjusting the position and / or size of the selected component, most interference situations can be basically eliminated. At the same time, the method of directly operating the image also greatly facilitates the user's operation.

[0134] To facilitate understanding of the method for selecting a family-oriented front hood design provided by the present application, a specific example is used below to illustrate the method, but the method protected by the present application is not limited to the example.

[0135] First, based on the constraints of the family-based front hood in terms of exterior styling, layout space, dent resistance, pedestrian head impact performance, and pattern stamping process, consider dividing the family-based front hood into four components: outer panel, inner panel, reinforcement, and inner panel pattern. In the process of designing the family-based front hood, the data models obtained after modeling each component are stored in a library. An outer panel module library, an inner panel module library, a reinforcement module library, and an inner panel pattern module library can be established; among them, the outer panel module library is dedicated to storing different data models of outer panels, the inner panel module library is dedicated to storing different data models of inner panels, the reinforcement module library is dedicated to storing different data models of reinforcements, and the inner panel pattern module library is dedicated to storing different data models of inner panel patterns. The data models in the above libraries are equivalent to the local data models in the above embodiments, which will not be described in detail here. After the aforementioned data models are stored in the library, they can be stored according to Fig.12 The front hood design is shown in Figure 1. Fig.12 As shown, including:

[0136] Start: The user / designer operates in the display interface of the terminal device and selects a data model from the above four libraries for each component of the family front hood.

[0137] S1201: Determine whether the front hood assembly is successfully matched. If yes, execute S1202, if no, prompt the user to continue to select a data model. The front hood assembly here can be understood as the family-based front hood data model in the above embodiment. No further details will be given here.

[0138] S1202: CAE meshing is performed on the family-based front hood data model or its corresponding three-dimensional image, and the family-based front hood data model is converted into data that can be used for CAE simulation. Then, simulation is performed from four simulation dimensions: modal analysis, collision safety analysis, stiffness analysis, and structural durability analysis.

[0139] S1203: DOE experiment result response: Display the simulation results under the above four simulation dimensions.

[0140] S1204: Confirmation of the optimal combination solution: Based on the simulation result of S1203, the family-based front hood data model with the best simulation result is determined as the optimal combination solution, but the method is not limited thereto.

[0141] S1205: Determine whether detail optimization is required. If not, end. If yes, execute S1206. Here, it can be determined whether detail optimization is required based on the actual needs of the user and the actual situation of the optimal combination solution in S1204. For example, a pop-up box can be provided to select whether to perform detail optimization.

[0142] S1206: CAE structure optimization. This optimization process is similar to the process in the above embodiment, in which the local data model in the target combination data model is fine-tuned according to the target fine-tuning rule to generate multiple candidate combination data models; each candidate combination data model is simulated respectively to obtain the simulation result of each candidate combination data model; the data model with the best simulation result among the multiple candidate combination data models and the target combination data model is determined as the family front hood data model. The optimal combination scheme is equivalent to the above target combination data model, which will not be repeated here.

[0143] The embodiment of the present application provides a modular modeling idea for a family-based front hood. In the application, modular assembly is used to generate multiple solutions that meet different requirements, providing a convenient way for solution selection and simplifying the design process of the family-based front hood. Rapid modeling in the early stage can provide more decision-making time for the optimization and performance balance of the later solutions.
