Description

Technical Field

[0001] This invention relates to the field of aerospace manufacturing technology, and in particular to a method, apparatus, equipment, medium and procedure for generating a shot peening coverage template. Background Technology

[0002] Currently, shot peening is widely used in the forming of integral wing panels for large and medium-sized passenger aircraft (including all currently operating Airbus and Boeing passenger aircraft) and transport aircraft. Therefore, shot peening technology for large integral wing panels is one of the core technologies in the manufacturing of large aircraft wings. After shot peening, the surface coverage needs to be measured, as the surface coverage of the part is a key quality indicator that directly affects strength and fatigue life.

[0003] Traditional methods for measuring coverage mainly rely on visual inspection, such as direct observation with magnifying glasses or microscopes, or evaluation after spraying a test coating. However, these methods have several drawbacks: First, they are time-consuming, labor-intensive, and computationally difficult, requiring careful manual observation and complex calculations; second, the results are greatly affected by the operator's experience and subjective judgment, and the measurement results from different personnel may vary significantly, making it difficult to achieve accurate and repeatable measurements; third, for large-area or complex-shaped parts, traditional methods are difficult to effectively evaluate and cannot meet actual measurement needs.

[0013] The simulated shot peening module is used to perform simulated shot peening on the current shot peening template with a simulated template as the current shot peening template and the theoretical shot quantity as the current shot peening quantity, so as to update the current shot peening template.

[0014] The additional shot peening module is used to calculate the actual coverage of the current shot peening sample, and when the difference between the actual coverage and the planned coverage is greater than the difference threshold, it calculates the additional shot peening quantity that needs to be added to the current shot peening sample.

[0015] The coverage rate judgment module is used to take the additional shot peening quantity as the new current shot peening quantity, and then return to execute the simulated shot peening operation in the current shot peening template to match the current shot peening quantity, until the difference between the actual coverage rate and the planned coverage rate is less than or equal to the difference threshold.

[0016] The solid template generation module is used to generate a solid shot peening template under the planned coverage based on the current shot peening template at the end of the iteration.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0032] Example 1

[0033] Figure 1 This is a flowchart of a shot peening coverage template generation method provided in Embodiment 1 of the present invention. This embodiment is applicable to the precise measurement of the coverage of shot peening formed on parts such as aircraft wing panels. The method can be executed by a shot peening coverage template generation device, which can be implemented in hardware and / or software and can be configured in a digital manufacturing system. Figure 1 As shown, the method includes:

[0034] S110. Based on the preset radius of the standard shot in the shot peening process and the size of the simulation template used to simulate shot peening formation, calculate the theoretical number of shot peening particles that need to be generated in the simulation template to meet the preset planned coverage rate.

[0035] Shot is the core medium in shot peening. In the aerospace manufacturing industry, during shot peening of aircraft wing panels, a high-speed stream of metal shot is ejected onto the wing panel surface, causing plastic deformation and forming the desired curvature. Shot acts like a tiny shaping tool; different sizes and materials of shot will have different effects on the shot peening effect. Taking standard shot with a preset radius of 0.6mm or 1.59mm as an example, the radius determines the size of the pit (a solid dot in simulated shot peening) formed on the surface of the part after shot peening by a single shot. In actual operation, the larger the shot radius, the larger the area of ​​the pit formed by a single shot, and the different the effects on the surface coverage and residual stress distribution of the part. If the shot radius is too large, it may lead to excessive deformation of the part surface, affecting its strength and fatigue life; if the radius is too small, the expected coverage and forming effect may not be achieved. Therefore, accurately selecting a shot with an appropriate radius is crucial to ensuring the quality of shot peening.

[0036] A simulation template is a tool used to simulate the shot peening process. Before actual production, simulation templates are used for testing to determine suitable shot peening parameters. For example, in automotive parts manufacturing, for some complex-shaped parts, to avoid waste from directly testing on expensive real parts, simulation templates are created that are similar in shape to the real parts but scaled down in size. In the process of generating the shot peening coverage template, the simulation template has a specific size, such as 20mm × 20mm. It provides a testing ground for simulated shot peening, where simulated shot peening operations are performed, coverage is calculated, and the amount and position of shot peening are adjusted until the preset planned coverage is achieved. By continuously optimizing the shot peening parameters on the simulation template and then applying these parameters to real parts in actual production, production efficiency can be greatly improved, production costs reduced, and product quality stability ensured.

[0037] In this embodiment of the invention, the planned coverage rate during the shot peening process of aircraft wing panels is set based on the design requirements and performance demands of the wing panels. Aircraft wings experience enormous stress during flight, and the coverage rate after shot peening directly affects the strength and fatigue life of the wing panels. For example, for a certain type of aircraft wing panel, to ensure its safe and reliable operation under specified flight mileage and load conditions, designers, after extensive experimentation and theoretical analysis, determined that the planned coverage rate would be set at 40%. This means that during shot peening, the pits formed by the shot impact on the wing panel surface should cover 40% of the wing panel's surface area. This planned coverage rate is achieved by precisely controlling shot peening parameters, such as shot velocity, flow rate, and spray time. When this coverage rate is achieved, a reasonable residual stress field can be formed inside the wing panel, effectively improving its fatigue resistance and ensuring aircraft flight safety.

[0038] First, based on the preset radius of the standard shot in the shot peening process, the area formula of a circle, S = π·r, is used. 2 Calculate the area of ​​a single dot in the simulated shot peening process for each projectile after it has formed. Next, obtain the dimensions (length and width) of the simulated shot peening template and calculate its area. Then, calculate the theoretical total shot peening area based on the simulated template area and the preset planned coverage rate (theoretical total shot peening area = simulated template area × planned coverage rate). Finally, obtain the theoretical shot peening quantity by the ratio of the theoretical total shot peening area to the area of ​​a single dot.

[0039] Optionally, based on the preset radius of the standard shot in the shot peening process and the size of the simulation template used to simulate shot peening formation, the theoretical number of shot particles required to be generated in the simulation template to meet the preset planned coverage rate can be calculated, which may include:

[0040] Based on the preset radius of the standard shot in the shot peening process, calculate the area of ​​a single dot of simulated shot peening for each shot after shot peening formation.

[0041] Obtain the dimensions of the simulated template used for shot peening, and calculate the area of ​​the simulated template based on the dimensions;

[0042] The theoretical total shot peening area is calculated based on the area of ​​the simulated template and the preset planned coverage rate, and the theoretical shot peening quantity is obtained by calculating the ratio between the theoretical total shot peening area and the area of ​​a single dot.

[0043] A simulated shot peening process with the theoretical shot peening quantity is generated in the simulated template.

[0044] Standard shot refers to shot with specific dimensions, material properties, etc., used in shot peening to ensure consistency and stability of the process. Preset radius is the radius value of a standard shot that is set in advance and is a fixed known parameter used for relevant calculations throughout the shot peening process and template generation. Simulated shot peening is a representation of a shot-like impact effect formed when the actual shot peening process is simulated on a simulated template. In this embodiment of the invention, it is represented by a single dot.

[0045] The simulated template serves as the carrier for shot peening simulation operations, and its dimensions determine the size of the area that can be peened. Knowing the dimensions of the simulated template (such as length and width), the total area of ​​the simulated template can be calculated using the corresponding geometric area calculation formulas (such as rectangle area = length × width). This area is a crucial basis for subsequent calculations of the theoretical total shot peening area and coverage, as it defines the scope of the shot peening action.

[0046] The preset planned coverage rate is a shot peening coverage ratio pre-set based on actual production needs and product quality requirements. Multiplying the area of ​​the simulated sample by the planned coverage rate yields the total area theoretically required to be shot peened under this coverage requirement, i.e., the theoretical total shot peening area. Dividing the theoretical total shot peening area by the previously calculated area of ​​a single dot gives the theoretical number of shot particles needed on the simulated sample to achieve the planned coverage rate. This step converts the required shot peening area into a specific number of shot particles, providing a clear quantitative basis for subsequent simulated shot peening operations.

[0047] S120. Using the simulated template as the current shot peening template and the theoretical shot quantity as the current shot peening quantity, perform simulated shot peening on the current shot peening template to match the current shot peening quantity, so as to update the current shot peening template.

[0048] The simulation template is a sample used to simulate the shot peening process. At the initial stage of generating the shot peening coverage template, it is used as the current object of operation, i.e., the current shot peening template. The theoretical shot quantity is calculated based on the preset radius of the standard shot in the shot peening process, the size of the simulation template, and the preset planned coverage. This quantity is the theoretically required shot quantity to achieve the planned coverage.

[0049] Through the above operations, the current state of the shot-peening sample is updated. Solid dots representing simulated shot peening appear on the previously blank sample. At this point, the sample's coverage status changes from no shot peening coverage to a certain degree of coverage, completing one simulated shot peening update of the sample. After each simulated shot peening operation, the sample's coverage and surface condition are different from before, thus updating the sample. This updated sample state provides a basis for subsequent calculations of the actual coverage and determining whether additional shot peening is needed.

[0050] Furthermore, performing simulated shot peening on the current shot peening template, matching the current shot peening quantity, can include:

[0051] The generation area of ​​the center coordinates is determined based on the current size of the shot peening sample, and a second number of random center coordinates are generated within the generation area, wherein the second number is greater than the first number;

[0052] In the generation area, a random center coordinate is assigned to each shot under the current shot peening quantity, and solid dots matching the current quantity are generated according to the random center coordinate and the preset radius of the shot to complete the simulated shot peening.

[0053] When the current shot peening quantity is updated, a random center coordinate is assigned to each additional shot under the new current shot peening quantity in the random center coordinates of the remaining quantity, and a solid circle matching the new current shot peening quantity is generated in the current shot peening template according to the random center coordinates and the preset radius of the shot, thus completing the additional simulated shot peening.

[0054] The remaining quantity is the difference between the second quantity and the current shot peening quantity.

[0055] The current shot peening template is the template undergoing simulated shot peening, and its size determines the effective range of the simulated shot peening. The generated area for the center coordinates is a coordinate value range set to ensure that the simulated shot peening occurs within the template's area. Random center coordinates are randomly generated coordinate values ​​used to determine the position of each simulated shot on the template. The first quantity is the number of shots to be simulated, which forms the basis for calculations and operations. The second quantity is the number of random center coordinates generated; it is greater than the first quantity to ensure sufficient coordinates for subsequent shot peening, guaranteeing the flexibility and accuracy of the simulation process.

[0056] Assigning random center coordinates involves mapping the generated random coordinates one-to-one with the simulated shot peening, ensuring that each simulated shot has a definite position. In a specific example, assuming the simulated template is 20mm × 20mm in size and the preset radius of the projectile is 0.6mm, 50 random center coordinates are generated within the [20,20] area corresponding to the template. Then, a random center coordinate is assigned to each of the 20 current shot peenings. A solid dot is drawn with each coordinate as the center and a radius of 0.6mm. These solid dots simulate the marks formed by the projectile impacting the template surface.

[0057] The current shot peening quantity update is due to the discrepancy between the actual and planned coverage, requiring adjustment of the shot peening quantity to achieve the target coverage. The remaining quantity refers to the unused quantity in the generated random center coordinates, providing coordinate resources for additional shot peening. Additional shot peening is a shot peening operation added to the original shot peening quantity, aiming to make the actual coverage of the sample closer to the planned coverage. Additional simulated shot peening is a simulation operation performed on additional shot peening, represented by the generation of solid circles.

[0058] S130. Calculate the actual coverage of the current shot peening sample, and when the difference between the actual coverage and the planned coverage is greater than the difference threshold, calculate the additional shot peening quantity that needs to be added to the current shot peening sample.

[0059] The coverage difference reflects the gap between the current actual coverage and the planned coverage; the additional shot peening area is the area that needs to be covered by additional shot peening to make the actual coverage reach the planned coverage; the additional shot peening quantity is the additional shot peening quantity that needs to be added based on the additional shot peening area.

[0060] After the initial simulated shot peening, the actual coverage rate is obtained by calculating the proportion of the area covered by solid dots on the current template to the total area of ​​the template. If there is a discrepancy between the actual coverage rate and the planned coverage rate, the shot peening quantity and position are further adjusted based on this updated template status, and simulated shot peening is performed again. This iterative optimization continues until the actual coverage rate approaches or reaches the planned coverage rate.

[0061] S140. After adding the shot peening quantity as the new current shot peening quantity, return to the execution of the simulated shot peening operation in the current shot peening template that matches the current shot peening quantity, until the difference between the actual coverage and the planned coverage is less than or equal to the difference threshold.

[0062] "Return to perform simulated shot peening on the current shot peening template, matching the current shot peening quantity" means returning to the simulated shot peening step and continuing the simulated shot peening based on the existing current shot peening template. By continuously repeating this process, adjusting the shot peening quantity each time based on the difference between the actual and planned coverage, and then performing simulated shot peening again, the coverage of the template gradually approaches the planned coverage, until the difference between the actual and planned coverage is less than or equal to the difference threshold, thus obtaining a shot peening template that meets the requirements.

[0063] S150. Generate a solid shot peening template with the planned coverage based on the current shot peening template at the end of the iteration.

[0064] By iteratively simulating shot peening and adjusting the shot peening quantity, the difference between the actual and planned coverage is kept within acceptable limits. For example, in manufacturing shot peening samples for aircraft wing panels, the shot peening process is continuously optimized to ensure the sample coverage meets design requirements.

[0065] This invention employs simulated shot peening, avoiding problems such as uneven coverage caused by improper operation or environmental factors in traditional shot peening processes. Furthermore, by controlling the simulated and subsequent shot peening processes through computer programs, the shot peening process is automated and intelligent, improving production efficiency and consistency. In actual production, this method enhances reliability and safety for shot peening of critical components such as aircraft wings. Whether for structural parts of large machinery or components of small precision instruments, this method can be used to generate corresponding shot peening coverage templates for effective process control and quality inspection, demonstrating strong versatility and adaptability.

[0066] Example 2

[0067] Figure 2 This is a flowchart of another method for generating shot peening coverage templates according to Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment, and correspondingly, as shown... Figure 2As shown, the method specifically includes:

[0068] S210. Based on the preset radius of the standard shot in the shot peening process and the size of the simulation template used to simulate shot peening formation, calculate the theoretical number of shot peened in the simulation template to meet the preset planned coverage rate.

[0069] S220. Using the simulated template as the current shot peening template and the theoretical shot quantity as the current shot peening quantity, perform simulated shot peening on the current shot peening template to match the current shot peening quantity, so as to update the current shot peening template.

[0070] S230. Calculate the actual total shot peening area of ​​the current shot peening sample based on the area of ​​a single dot and the current shot peening quantity.

[0071] During simulated shot peening, the area of ​​each individual dot formed by each simulated shot peening is known, calculated from the preset radius of the standard shot. The current shot peening quantity refers to the number of simulated shot peenings already generated on the template during the current simulated shot peening operation. Multiplying the area of ​​each individual dot by the current shot peening quantity yields the total area formed by all simulated shot peenings on the current shot peening template, i.e., the actual total shot peening area. This step is fundamental to determining the actual coverage rate, providing data support for subsequent coverage rate calculations by quantifying the size of the shot peening coverage area.

[0072] S240. The actual coverage of the current shot-peened sample is obtained by calculating the ratio of the area of ​​a single dot to the total actual shot-peened area.

[0073] After obtaining the actual total shot peening area, the area of ​​a single dot is divided by the actual total shot peening area. The resulting ratio is the actual coverage of the current shot peening sample. This actual coverage reflects the degree of coverage of the current simulated shot peening on the sample. By comparing it with the planned coverage, it can be determined whether the effect of the current simulated shot peening has met expectations, and thus decide whether it is necessary to adjust the shot peening quantity or other parameters.

[0074] S250. Calculate the difference between the planned coverage rate and the actual coverage rate to obtain the coverage rate difference value, and multiply the simulated sample area by the coverage rate difference value to obtain the additional shot peening area.

[0075] Multiplying the difference between the simulated sample area and the coverage rate gives the additional area that needs to be shot-peened in order for the actual coverage rate to reach the planned coverage rate.

[0076] S260. By calculating the ratio of the additional shot peening area to the area of ​​a single dot, the number of additional shot that needs to be added to the current shot peening template is obtained.

[0077] Given the additional shot peening area and the area of ​​a single dot, dividing the additional shot peening area by the area of ​​a single dot yields the number of additional shot pieces needed to be added to the current shot peening sample to achieve the planned coverage. This number of additional shot pieces is a key parameter for the next step of simulated shot peening, allowing the actual coverage of the sample to more closely approximate the planned coverage.

[0078] S270. After adding the shot peening quantity as the new current shot peening quantity, return to the execution of the simulated shot peening operation in the current shot peening template that matches the current shot peening quantity, until the difference between the actual coverage and the planned coverage is less than or equal to the difference threshold.

[0079] S280. Export the current shot peening template at the end of the iteration as a template image, and use laser printing technology to print the template image on a film plate to form a physical shot peening template under the planned coverage, so as to provide a basis for the coverage measurement of the Almen test piece to be tested.

[0080] The solid shot peening template is the final template with practical application value, used to compare and measure coverage with the Almen test piece to be tested; the Almen test piece is a standard test piece used in the shot peening process to test and evaluate the shot peening effect.

[0081] The shot-peened samples with different coverage rates were compared with the Almen test specimen in turn. Visual comparison can be used to directly observe the similarity between the shot-peening marks on the specimen surface and the sample; alternatively, auxiliary tools such as a magnifying glass can be used to examine details more clearly. If the shot-peening marks on the specimen surface are most similar to the 40% coverage sample, the specimen coverage is preliminarily judged to be close to 40%. For measurement scenarios requiring higher precision, image analysis software can be used. Images of the specimen and sample can be imported into the software, and the software can measure and analyze data such as the pixel ratio of the shot-peened area in the image to obtain a more accurate coverage value, thereby accurately determining whether the specimen coverage meets the design requirements.

[0082] The technical solution of this invention refines the overall solution, focusing on "how to perform simulated shot peening matching the current shot peening quantity on the current shot peening template" and "how to accurately calculate and add shot peening quantity to approximate the planned coverage when there is a deviation between the actual coverage and the planned coverage." Specifically, by randomly assigning center coordinates and generating solid dots, a random and uniform distribution of simulated shot peening is achieved, improving the simulation accuracy of shot peening coverage. By calculating the coverage difference and adding shot peening area, the shot peening coverage is ensured to gradually approach the planned coverage, achieving precise adjustment and control of the shot peening quantity, thereby ensuring the accuracy and reliability of the shot peening coverage. Finally, the generated solid shot peening template can also serve as a quality control standard, used to detect and evaluate whether the coverage of the Almen specimen meets the requirements, helping to improve evaluation quality and performance.

[0085] The shot peening quantity calculation module 310 is used to calculate the theoretical number of shot peening particles that need to be generated in the simulated template to meet the preset planned coverage rate, based on the preset radius of the standard shot in the shot peening process and the size of the simulated template used to simulate shot peening formation.

[0086] The simulated shot peening module 320 is used to perform simulated shot peening matching the current shot peening quantity on the current shot peening template after taking the simulated template as the current shot peening template and taking the theoretical shot quantity as the current shot peening quantity, so as to update the current shot peening template.

[0087] The additional shot peening module 330 is used to calculate the actual coverage of the current shot peening sample, and when the difference between the actual coverage and the planned coverage is greater than the difference threshold, it calculates the additional shot peening quantity that needs to be added to the current shot peening sample.

[0088] The coverage rate judgment module 340 is used to take the additional shot peening quantity as the new current shot peening quantity, and then return to execute the simulated shot peening operation in the current shot peening template that matches the current shot peening quantity, until the difference between the actual coverage rate and the planned coverage rate is less than or equal to the difference threshold.

[0089] The solid template generation module 350 is used to generate a solid shot peening template under the planned coverage based on the current shot peening template at the end of the iteration.

[0090] This invention employs simulated shot peening, avoiding problems such as uneven coverage caused by improper operation or environmental factors in traditional shot peening processes. Furthermore, by controlling the simulated and subsequent shot peening processes through computer programs, the shot peening process is automated and intelligent, improving production efficiency and consistency.
