Detailed Implementation
[0021] Lifting lugs, as load-bearing components installed on equipment for lifting, are crucial connecting parts in the equipment hoisting process and directly affect the safety of hoisting. To ensure the safety of hoisting operations and prevent hoisting accidents, lifting lugs need to be checked. Lifting lug check refers to the process of verifying the mechanical strength, stiffness, and stability of the lifting lugs during hoisting operations through engineering calculations and simulation analysis, thereby ensuring that the lifting lugs can safely bear the load during hoisting without structural damage.
[0022] In related technologies, when performing lifting lug verification, the entire object being lifted with the lifting lugs installed is modeled using CAE, and the geometric model after modeling is simulated and analyzed to achieve the verification of the lifting lugs.
[0023] However, the overall CAE modeling in related technologies requires a long time to complete, and the simulation calculation after modeling involves a comprehensive analysis of the entire object being lifted, which requires a long time and a large amount of analysis and calculation, making it difficult to guarantee the efficiency of the lifting lug verification.
[0024] In view of this, embodiments of this application provide a method, apparatus, device, storage medium, and program product for calibrating lifting lugs. In the lifting lug calibration process, before performing finite element analysis on the three-dimensional digital model of the object being lifted based on the load of the lifting lugs, the three-dimensional digital model is simplified to reduce the computational load of the lifting lug calibration, thereby reducing the time occupied by the lifting lug calibration and improving the efficiency of the lifting lug calibration.
[0025] To provide a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0028] The method embodiments of this application will be described below.
[0029] Combination Figure 1 As shown, this application embodiment provides a hoisting application scenario corresponding to a multi-lug hoisting process. The scenario includes a hook 11, multiple lifting ropes 12, multiple lifting lugs 13, and an object 14 to be hoisted. Multiple lifting lugs 13 are mounted on the object 14, and the number of lifting ropes 12 is the same as the number of lifting lugs 13. Each lifting lug 13 is connected to the hook 11 via a lifting rope 12. During the hoisting operation, the force transmission process is as follows: the lifting power is transmitted to the object 14 through the hook 11, multiple lifting ropes 12, and multiple lifting lugs 13, realizing the lifting and displacement of the object 14.
[0030] The above Figure 1 The hoisting process described is for illustrative purposes only. In actual hoisting scenarios, the hoisted object 14 is not limited to a cuboid shape. For example, during the installation of a wind turbine, the gearbox being hoisted is not a cuboid but an irregular shape.
[0031] Based on the above-mentioned hoisting scenarios, this application provides a method for verifying lifting lugs. This method can be applied to electronic devices. The electronic devices support simulation software used in the lifting lug verification process, such as software for building three-dimensional digital models (creo software), finite element analysis software (ANSYS software), etc. For example, the electronic devices can be tablet computers, laptops, desktop computers, and servers.
[0032] Combination Figure 2 As shown in the embodiment of this application, the method for checking the lugs includes the following steps: S21. Determine the coordinates of multiple lifting lugs in the three-dimensional digital model of the object being lifted.
[0033] In step S21, the three-dimensional digital model of the object being hoisted can be a Creo model. The Creo model can be opened using Creo software. The Creo software interface has a preset coordinate system for the three-dimensional digital model. By obtaining the lifting lugs created by the user in the Creo software display interface, the coordinates of each lifting lug can be determined.
[0034] S22, by analyzing the three-dimensional digital model of the object being lifted, the weight and center of gravity coordinates of the object being lifted are determined.
[0035] In step S22, the weight and center of gravity coordinates of the object being lifted can be determined by responding to the user's analysis operation through the Creo software. Based on this, combined with the coordinates of multiple lifting lugs and the preset lifting rope length, parameter information for calculating the load on the lifting lugs can be obtained.
[0036] S23, based on the preset length of the lifting rope, the coordinates of multiple lifting lugs, the weight and center of gravity coordinates of the object being lifted, calculate the load on each lifting lug.
[0037] In step S23, after obtaining the parameter information used to calculate the load on the lifting lugs, namely the coordinates of each lifting lug, the weight and center of mass coordinates of the object being lifted, and the preset length of the lifting rope, the parameter information can be input into the pre-packaged load calculation model. The load calculation model can simulate and calculate the load on each lifting lug based on the above parameter information. During the simulation calculation, the length of each lifting rope is the same.
[0038] The load calculation model can be implemented using an Excel spreadsheet. Specifically, users can pre-set the formulas required for calculating the load of the lifting lugs in the cells of the Excel spreadsheet. Then, by inputting the parameter information into the Excel spreadsheet, the load of the lifting lugs can be calculated.
[0039] S24 simplifies the three-dimensional digital model of the object being hoisted.
[0040] In step S24, during the lifting lug verification process, the key component is the lifting lug. Therefore, the 3D digital model of the object being lifted can be simplified by removing detailed features of non-essential components other than the lifting lug from the 3D digital model of the object being lifted. For example, using the Creo model, the simplified model can be exported as an STP format.
[0041] S25. Based on the load of each lifting lug, a simplified three-dimensional digital model is subjected to finite element analysis to verify each lifting lug.
[0042] In step S25, taking ANSYS software as an example of finite element analysis software, the STP format file exported after simplifying the Creo model is imported into ANSYS software, and the mesh of the lug structure is refined to achieve a detailed analysis of the lug.
[0043] The loads of each lifting lug are applied to each lifting lug separately, and stress analysis is performed using an inertial release algorithm to verify each lifting lug.
[0044] In the lifting lug verification method provided in this application embodiment, the electronic device can determine the coordinates of each lifting lug in the three-dimensional digital model of the object being lifted during the verification of multiple lifting lugs. By analyzing the three-dimensional digital model of the object being lifted, the weight and center of gravity coordinates of the object are determined. Based on the preset lifting rope length, the coordinates of each lifting lug, the weight and center of gravity coordinates of the object being lifted, the load on each lifting lug is calculated. Before performing finite element analysis based on the three-dimensional digital model of the object being lifted, the three-dimensional digital model is simplified. Based on the loads of each lifting lug, finite element analysis is performed on the simplified three-dimensional digital model, thus enabling the verification of each lifting lug.
[0045] In this embodiment of the application, after calculating the load of each lifting lug during the verification of multiple lifting lugs, the electronic device simplifies the three-dimensional digital model of the object being lifted and performs finite element analysis based on the simplified three-dimensional digital model. This reduces the amount of calculation required for finite element analysis, thereby reducing the time required for finite element analysis and improving the efficiency of lifting lug verification.
[0046] The following describes optional implementation methods for the lug verification method provided in the embodiments of this application.
[0047] In step S23 above, the process of calculating the load of each lifting lug in the load calculation model includes: based on the preset lifting rope length, the coordinates of multiple lifting lugs, and the coordinates of the center of mass of the object being lifted, calculating the coordinates of each lifting point corresponding to the upper end of each lifting rope. Based on the coordinates of each lifting point, determining whether the center of mass of the object being lifted has shifted. If the center of mass of the object being lifted has shifted, adjusting the length of the target lifting rope according to the direction of the shift; wherein the target lifting rope is located in the direction of the shift, or in the opposite direction of the shift. After the length of the target lifting rope is adjusted, calculating the load of each lifting lug based on the weight of the object being lifted.
[0048] In this embodiment, since the lifting point is usually located directly above the center of mass of the object being lifted during the hoisting process, the X and Y coordinates of the lifting point in the XY plane of the coordinate system of the three-dimensional digital model of the object being lifted are the same as the X and Y coordinates of the center of mass. Given that the X and Y coordinates of the lifting point, as well as the length of the lifting rope and the coordinates of the lifting lugs, are known, the Z coordinate of the lifting point can be calculated based on the Pythagorean theorem, thus obtaining the coordinates of the lifting point. Figure 3 Taking the simulated hoisting scenario shown as an example, when the center of gravity of the hoisted object shifts, the coordinates of the four hoisting points are obtained corresponding to the upper ends of the four hoisting ropes.
[0049] Ideally, assuming the center of gravity of the object being lifted does not shift, the Z-coordinates of the upper ends of the four fixed-length lifting ropes are the same or similar, meaning the Z-coordinates of the four lifting points are the same or similar. Therefore, by calculating the GAP (Gap Average) value of the Z-coordinates among the four lifting points, it can be determined whether the center of gravity of the object being lifted has shifted. Figure 3 Taking the hoisting scenario shown as an example, the difference in Z-coordinates between hoisting points A and B is calculated to obtain GAP1. The difference in Z-coordinates between hoisting points C and D is calculated to obtain GAP2. The difference between the maximum and minimum Z-coordinates among the four hoisting points, i.e., the difference in Z-coordinates between hoisting points A and D, is calculated to obtain GAP3. With a fixed rope length, a smaller GAP value indicates that the Z-coordinates of different hoisting points are closer, and also indicates a smaller displacement of the center of gravity of the hoisted object. Therefore, by determining whether GAP1, GAP2, and GAP3 are greater than the GAP threshold, it can be determined whether the center of gravity of the hoisted object has shifted.
[0050] When the center of gravity of the lifted object shifts, the shift can be corrected by adjusting the length of the lifting rope in the direction of the shift or in the opposite direction. After the lifting rope length adjustment is completed and the center of gravity shift of the lifted object is corrected, the load on each lifting lug can be calculated based on the weight of the lifted object. The specific calculation process is as follows: by Figure 1 Taking the scenario of lifting with four lifting lugs as an example, the sum of the components of the force on all the lifting lugs in the Z direction is equal to the weight of the object being lifted. The weight of the object being lifted is obtained based on the weight of the object being lifted, and the specific formula is as follows: (1) In formula (1), G represents the weight of the object being lifted, and F1, F2, F3 and F4 represent the tension of the lifting ropes on the four lifting lugs, respectively. , , and These represent the components of the rope tension acting on the four lugs in the Z direction.
[0051] In the simulated lifting scenario, the moment of the object being lifted in the XZ plane can be considered to be balanced. By taking the distance between the lifting lug and the center of mass, the following formula can be obtained: (2) In formula (2), , , and These represent the distance of the lug from the center of mass in the X direction. , , and Let F1 and F2 represent the distances of the lifting lugs from the center of mass in the Z direction. In the above formulas (1) and (2), the forces F1 and F2 on the two lifting lugs on the left can be considered equal, and the forces F3 and F4 on the two lifting lugs on the right can be considered equal. Solving formulas (1) and (2) will yield F1, F2, F3 and F4. Finally, the component forces of F1, F2, F3 and F4 in the XYZ directions are calculated to obtain the loads of the four lifting lugs.
[0052] By adopting this implementation method, the displacement of the center of gravity of the hoisted object can be corrected during the calculation of the load on the lifting lug. After the center of gravity of the hoisted object is corrected, the load on the lifting lug can be calculated more accurately, reducing the impact of the displacement of the center of gravity of the hoisted object on the load on the lifting lug.
[0053] Furthermore, the length of the target suspension rope is adjusted according to the direction of the center of gravity shift, including: shortening the length of the target suspension rope when it is in the direction of the center of gravity shift, and lengthening the length of the target suspension rope when it is in the opposite direction of the center of gravity shift.
[0054] In this implementation, Figure 3 Taking the scenario of the hoisted object's center of gravity shifting as an example, when the center of gravity shifts to the right, the length of the right-side hoisting rope can be shortened or the length of the left-side hoisting rope can be extended according to the shift, thereby correcting the center of gravity shift. The shift amount can be determined based on the center of gravity's shift coordinates or the GAP value calculated in the aforementioned embodiments. By adjusting the hoisting rope length, the GAP value can be made to approach zero.
[0055] Optionally, in step S25 above, each lifting lug is checked, including: for each lifting lug, comparing the maximum stress and allowable stress of the lug. If the maximum stress of the lug is less than the allowable stress, the lug is determined to have passed the check. If the maximum stress of the lug is greater than or equal to the allowable stress, the lug is determined to have failed the check.
[0056] In this implementation, after applying loads to each lifting lug on the simplified 3D digital model, the lifting lug verification is determined by comparing the maximum stress and the allowable stress. The allowable stress refers to the maximum stress value the lifting lug can withstand, obtained by processing the safety factor using the yield strength. During the lifting lug verification process, if the maximum stress of the lifting lug is less than the allowable stress, it indicates that the lifting lug is in a safe state, and the verification passes. If the maximum stress of the lifting lug is greater than or equal to the allowable stress, it indicates that the stress on the lifting lug has exceeded the critical value for a safe state, and the verification fails. Thus, by comparing the maximum stress and the allowable stress during the lifting lug verification process, it can be determined whether the lifting lug is in a safe state. Based on the safety status of the lifting lug, it can be determined whether the lifting lug meets the lifting requirements, thereby facilitating the optimization of the lifting lug design.
[0057] Furthermore, if the lifting lug fails the verification, a strain assessment can be performed based on the maximum stress of the lifting lug and the material of the lifting lug to determine whether the lifting lug structure is safe.
[0058] In this implementation, the failure of the lug verification only indicates a safety risk. Whether the lug structure is damaged requires a strain assessment, i.e., plastic limit analysis. When assessing the strain of the lug, the maximum stress and material-related parameters need to be considered. The main material-related parameters are the elastic modulus and yield strength. Specifically, the square of the maximum stress of the lug is divided by the elastic modulus and then by the yield strength. The calculated value reflects the strain level of the lug. This value is compared with a strain level threshold. If the value is less than the threshold, it indicates that the lug deformation is small, meaning the lug structure is within a safe range. If the value is greater than or equal to the strain level threshold, it indicates that the lug deformation is large, meaning the lug structure has undergone irreversible deformation, causing damage. The strain level threshold can be preset according to the lug material, for example, 1%.
[0059] By adopting this implementation method, if the lifting lug fails the verification, that is, if the lifting lug has a safety hazard, further plastic limit analysis can be performed on the lifting lug to clarify the critical point of lifting lug failure and realize the assessment of the lifting lug's limit state, which is conducive to optimization in the lifting lug design process.
[0060] The following describes the product embodiments provided in this application.

[0069] Optionally, the verification module 405, when verifying each lifting lug, specifically compares the maximum stress and allowable stress of each lifting lug.
