Description
Technical Field
[0001] The present invention belongs to the field of automobile technology, and in particular relates to a wheel wind deflector design method, device, terminal and storage medium taking into account engineering performance limitations. Background Art
[0002] During the automobile design process, the design of wheel deflectors is related to aerodynamic performance, vehicle passability, refinement, NVH performance, etc., and is an important part of automobile exterior design. Existing design methods often only limit the size or position boundaries such as passability and design boundaries to guide the deflector design. This method can achieve engineering feasible tire deflector parts, but does not take into account the needs of various engineering disciplines. After the design is completed, various engineering disciplines will intervene in the verification, resulting in repeated changes and adjustments to the deflector boundaries, increasing the R&D cycle and reducing R&D efficiency. Summary of the invention
[0003] The present invention provides a wheel wind deflector design method, device, terminal and storage medium that take engineering performance limitations into consideration, which can realize adding engineering professional demand limitations in the early stage of wheel wind deflector design, and reduce the problems of repeated design schemes, prolonged R&D cycle, reduced R&D efficiency, etc. caused by introducing engineering professional performance limitations after the wheel wind deflector is engineered.
[0004] The present invention is achieved through the following technical solutions:
[0005] In a first aspect, the present invention provides a method for designing a wheel wind deflector taking into account engineering performance limitations, which specifically comprises the following steps:
[0006] Step 1: Determine the design requirements of the wheel wind deflector;
[0007] Step 2: Collect boundary constraints of the wheel wind deflector and related engineering professional constraints;
[0008] Step 3: Perform parametric modeling based on the boundary constraints of the wheel wind deflector and related engineering professional constraints;
[0009] Step 4: Verify the size boundary and engineering professional restrictions based on the model established in step 3;
[0010] Step 5: Engineering the designed preliminary version data to complete the engineering data design;
[0011] Step 6: Check the engineering data for size, strength, and engineering performance requirements to determine whether the engineering data meets the requirements;
[0012] Step 7: The verified engineering data is reviewed by experts to confirm that all size, strength, and engineering performance constraints are met. If so, proceed to the next step. If not, identify the problem points, return to step 5 for optimization, and re-review until it passes the review;
[0013] Step 8: Complete the wheel wind deflector design;
[0014] After the review, the data is frozen, and relevant samples are processed to verify the test plan. After the test meets the requirements, a relevant test approval report is issued and the wheel wind deflector design is completed.
[0015] Furthermore, step one specifically includes the following contents:
[0016] According to the design requirements of the wheel windshield, the wind resistance target of the whole vehicle is decomposed, and the required amount of windshield resistance reduction is clarified. At the same time, the basic coverage area needs to be confirmed.
[0017] Among them, the design requirements include: boundary constraints of the wheel wind deflector and related engineering professional constraints.
[0018] Furthermore, the boundary constraints of the wheel wind deflector include the project development cycle, wind deflector installation method, wind deflector assembly method and whether it is divided into parts, materials, cost, and weight;
[0019] The relevant engineering professional restrictions include input information of the project development cycle, deadline for input of optimization plan, dates of key R&D node, test verification pass date, completion date, wind baffle installation, delivery method, materials, cost, weight requirements, and processing technology requirements.
[0020] Furthermore, step 2 specifically includes the following contents:
[0021] Determine the size limit of the wind stopper according to the parts of the wind stopper and pedestrian guard plate;
[0022] Collect relevant engineering professional constraints, including: perceived quality, aerodynamics, water management, NVH, maintainability, and vehicle passability.
[0023] Furthermore, in step four, if the conditions are met, proceed to the next step. If not, identify the problem points, feed back the preliminary version of the data to the relevant profession, conduct solution verification and simulation analysis, collect professional opinions and optimize the solution until the professional restrictions are met.
[0024] Furthermore, in step five, an engineering solution is designed based on the data that meets the size and professional performance requirements, and fillets and fixing points are added.
[0025] Furthermore, in step six, if the requirements are met, proceed to the next step. If the requirements are not met, it is necessary to identify the problem points, return to step five, re-perform engineering design, and then repeat the size, strength, and engineering professional performance requirement verification until the requirements are met.

[0028] Compared with the prior art, the advantages of the present invention are as follows:
[0029] The present invention discloses a wheel deflector design method, device, terminal and storage medium that take into account engineering performance limitations. In addition to introducing size boundary limitations at the initial design stage, the design considers the limitations of related engineering professional requirements and introduces performance limitations such as perceived quality visibility and passability in advance to prevent the situation in which the professional limitations are not met in the later stage of scheme engineering, resulting in the inability to optimize due to cycle problems and the only way to make adjustments is to simply cut the scheme. At the same time, limitations such as processing methods and processing materials are introduced in advance to prevent the situation in which the later design data cannot be engineered. Based on the above advantages, the consistency between the data state in the design stage of the wheel deflector and the engineering data state can be effectively guaranteed, and the engineering data scheme can be prevented from failing. At the same time, the scheme repetition is reduced, the design cycle is shortened, and the repetitive work in the design and manufacturing process of the wheel deflector is reduced.

[0037] Example 1
[0038] like Figure 1 FIG. 1 is a flow chart of a method for designing a wheel wind deflector taking into account engineering performance limitations in this embodiment. The method specifically includes the following steps:
[0039] Step 1: Start designing the wheel wind deflector;
[0040] Receive the design requirements of the wheel spoiler, decompose the wind resistance target of the whole vehicle, clarify the required amount of wind spoiler drag reduction, and confirm the initial requirements such as the basic coverage area (design scope of the spoiler component);
[0041] Step 2: Clarify the design limitations and requirements of the wheel wind deflector, including the project development cycle, wind deflector installation method, wind deflector assembly method and whether it is divided into parts, materials, cost, weight, etc., and set a development plan;
[0042] Collection of guard plate design engineering requirements, including project development cycle (input information required for each project node, deadline for input of optimization plan, dates of each key R&D node, test verification passing date, completion date, etc.), wind deflector installation, delivery method (wind deflector is a separate component or integrated with wheel cover or wind deflector is composed of wheel cover and pedestrian guard plate), materials (resin or felt, etc.), cost (design and development fee, mold fee, material fee, test approval fee, etc.), weight requirement (part weight requirement meets the comprehensive evaluation cost and lightweight requirements under the condition of part strength), processing technology requirements (stamping, injection molding, etc.);
[0043] Step 3: Collect size boundary restrictions and engineering professional restrictions related to wind baffles;
[0044] Determine the size limit of the wind spoiler according to the components of the wind spoiler and pedestrian guard (for example, if the approach angle is 13° and the minimum ground clearance of the vehicle is 120mm, the size of the wind spoiler should meet the boundary limit at the same time, and the position of the fixed point needs to be determined, and the spoiler profile should avoid the fixed point as much as possible to prevent the profile from being discontinuous);
[0045] Collect relevant engineering professional restrictions, such as perceived quality (no obvious leakage of the wind spoiler, beautiful design of the wind spoiler, etc.), aerodynamics (wind spoiler surface continuity, wind spoiler wind resistance sensitive area), water management (the wind spoiler should meet the requirements of wading and have a drainage structure), NVH (the electric vehicle wind spoiler has a buzzer sound transmission structure, etc.), maintenance convenience (the wind spoiler is easy to disassemble), vehicle passability (the wind spoiler meets most working conditions without the risk of collision), etc.;
[0046] Step 4: Perform parametric modeling based on boundary restrictions and wind-block-related engineering restrictions;
[0047] Based on the engineering professional restrictions collected in step three, the initial version of the wheel wind deflector profile is designed. In addition to considering the drag reduction performance, engineering issues such as materials (affecting strength), processing methods (affecting the detailed characteristics of the finished product) and component division methods (affecting the continuity of the profile, detailed characteristics, etc.) are also considered simultaneously. At the same time, relevant engineering professional restrictions are considered simultaneously to ensure boundary validity and engineering feasibility.
[0048] Step 5: Check and optimize the initial version of the wheel wind deflector engineering;
[0049] Check the size boundary and engineering professional restriction conditions of the initial version of the wheel wind deflector designed in step 4. If the conditions are met, proceed to the next design. If not, identify the problem points, feedback the initial version data to the relevant professionals, conduct solution verification and simulation analysis, collect professional opinions and optimize the solution until the professional restriction conditions are met;
[0050] Step 6: Engineering the designed preliminary version data to complete the engineering data design;
[0051] Engineering solutions are designed based on data that meets size and professional performance requirements, including adding rounded corners, fixing points, etc.
[0052] Step 7: Check the engineering data for size, strength, and engineering performance requirements to determine whether the engineering data meets the requirements. If it does, proceed to the next step. If it does not, identify the problem points, return to step 6, re-engineer the design, and then repeat the size, strength, and engineering performance requirements until the requirements are met. For example, to meet the wading strength requirements, the engineering data will add drainage holes and reinforcement ribs. The hole position and reinforcement rib form will affect the effect of the wind blocker. At the same time, the engineering data will add fixed points. The location and depth of the fixed points will affect the effect of the solution, and all need to be repeatedly checked and optimized.
[0053] Step 8. Subject the verified engineering data to expert review to confirm that all size, strength, and engineering performance constraints are met. If so, proceed to the next step. If not, identify the problem points, return to step 6 for optimization, and re-evaluate until passed.
[0054] Step 9: Complete the wheel wind deflector design;
[0055] After the plan passes the review, the data is frozen, and relevant samples are processed to verify the test plan. After the test meets the requirements, a relevant test approval report is issued and the wheel wind deflector design is completed.
