It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0025] like Figure 1 As shown, the present application provides a method for detecting the performance reliability of a high-profile skid landing gear, which is applied to a high-profile skid landing gear performance reliability detection system, and the method includes:

[0026] Step S100: Obtaining performance calculation results of the high-profile skid landing gear to be tested;

[0027] In one embodiment, step S100 of the present application further includes:

[0028] Step S110: Calculating the stiffness and strength of the high-attitude ski landing gear to be tested based on the landing condition type to obtain stiffness and strength calculation results;

[0029] In one embodiment, step S110 of the present application further includes:

[0030] Step S111: the landing condition types include vertical landing condition, landing condition with forward flight speed, sideways landing condition and single skid horizontal landing condition;

[0031] Step S112: performing stiffness calculations on each component of the high-profile skid landing gear to be tested based on the landing condition type, wherein the components of the high-profile skid landing gear to be tested include a front cross tube, a rear cross tube, a skid tube, a boarding step, and a maintenance step, and obtaining stiffness calculation results;

[0032] Step S113: performing strength calculation on each component of the high-profile skid landing gear to be tested based on the landing condition type to obtain a strength calculation result;

[0033] Step S114: obtaining the stiffness-strength calculation result based on the stiffness calculation result and the strength calculation result.

[0034] Specifically, the method provided in this application is used to test the performance reliability of a high-profile skid landing gear. First, the landing conditions of a helicopter's onboard high-profile skid landing gear are classified to obtain the landing condition type. The landing condition refers to the contact between the onboard high-profile skid landing gear and the ground when the helicopter lands. Due to different landing conditions, the center of gravity of the onboard high-profile skid landing gear is also different, and the stiffness and strength of each component are also different. The landing condition types include helicopter vertical landing conditions, helicopter landing conditions with forward flight speed, helicopter sideways landing conditions, and helicopter single-skid horizontal landing conditions. The components of the high-profile skid landing gear to be tested include five major components: the front cross tube of the landing gear, the rear cross tube of the landing gear, the landing gear slide tube, the boarding pedal, and the maintenance pedal. Vertical loads are applied to each component of the high-profile skid landing gear to be tested, and the stiffness curves of the front and rear cross tubes are calculated. The stiffness calculation results are further calculated. Then, strength calculations are performed on each component of the high-attitude skid landing gear to be tested, based on various landing conditions. Strength calculation results are obtained, including stress values ​​and residual strength coefficients. Rigidity calculation results are further obtained, including both the stiffness calculation results and the strength calculation results. Obtaining these rigidity calculation results provides data support for the subsequent performance calculation results.

[0035] Step S120: performing landing performance calculation on the high-profile skid landing gear to be tested to obtain a landing performance calculation result;

[0036] In one embodiment, step S120 of the present application further includes:

[0037] Step S121: obtaining the ground reaction forces of the front and rear cross tubes of the high-profile skid landing gear to be tested;

[0038] Step S122: Obtaining deformations of the front and rear transverse tubes of the high-profile skid landing gear to be tested;

[0039] Step S123: Calculating a performance relationship curve based on the ground reaction force and the deformation;

[0040] Step S124: Obtain the landing performance calculation result according to the performance relationship curve:

[0041] Step S130: Obtaining the performance calculation result based on the stiffness calculation result and the landing performance calculation result.

[0042] Specifically, a helicopter landing test is conducted on the high-profile skid landing gear to be tested based on different landing conditions. Parameters such as the front cross tube height, rear cross tube height, and helicopter center of gravity coordinates of the high-profile skid landing gear to be tested are first obtained. The distance from the helicopter center of gravity to the front cross tube and its vertical height to the ground are then calculated. The ground reaction forces of the front and rear cross tubes of the high-profile skid landing gear to be tested are then calculated. The deformation of the front and rear cross tubes of the high-profile skid landing gear to be tested is then measured. The work of the front and rear cross tubes is calculated based on the material, structure, and deformation of the front and rear cross tubes of the high-profile skid landing gear to be tested. A relationship curve between the ground reaction force P and the deformation δ of the front and rear cross tubes is calculated, and the area within the relationship curve is further calculated to obtain the absorbed work, thereby obtaining the landing performance calculation results. Finally, the performance calculation results are obtained, which include the stiffness calculation results and the landing performance calculation results. By obtaining the performance calculation results, original data support is provided for the next step of obtaining actual performance reliability prediction results.

[0043] Step S200: obtaining historical performance calculation results and actual performance reliability results of a plurality of high-profile skid landing gears, wherein the historical performance calculation results and the actual performance reliability results have a corresponding relationship;

[0044] Specifically, based on big data technology, a query is performed to obtain historical performance calculation results and actual performance reliability results for multiple high-profile ski landing gear. The actual performance reliability results indicate whether a landing accident occurred during a helicopter flight due to the onboard high-profile ski landing gear. The actual performance reliability results are represented by an actual performance reliability coefficient. The smaller the actual performance reliability coefficient, the lower the number of landing accidents. A value of 0 indicates that no landing accidents have occurred. The historical performance calculation results and the actual performance reliability results have a one-to-one correspondence. By obtaining the historical performance calculation results and the actual performance reliability results, raw data is provided for the next step of correlation analysis.

[0045] Step S300: performing a correlation analysis on the historical performance calculation result and the actual performance reliability result to obtain a correlation analysis result;

[0046] In one embodiment, step S300 of the present application further includes:

[0047] Step S310: performing a correlation evaluation on the historical performance calculation results and the actual performance reliability results to obtain a plurality of correlation evaluation coefficients;

[0048] Step S320: screening the plurality of correlation evaluation coefficients based on the correlation evaluation coefficient threshold, and obtaining a plurality of correlation evaluation results corresponding to the plurality of correlation evaluation coefficients that meet the correlation evaluation coefficient threshold;

[0049] Step S330: performing feature fusion on the multiple correlation evaluation results to obtain the correlation analysis result.

[0050] Specifically, a correlation evaluation is performed on multiple groups of the historical performance calculation results and the actual performance reliability results. The correlation evaluation refers to exploring the relationship between the historical performance calculation results and the multiple actual performance reliability results of the products, and obtaining multiple correlation evaluation coefficients. The correlation evaluation coefficient is used to measure the coefficient index of the relationship between the historical performance calculation results and the multiple actual performance reliability results of the products. The larger the correlation evaluation coefficient is, the closer the relationship between the two is. A correlation evaluation coefficient threshold is set, and the correlation evaluation coefficient threshold can be customized according to the size of the correlation evaluation coefficient. The multiple correlation evaluation coefficients are screened by the correlation evaluation coefficient threshold, and the multiple correlation evaluation results corresponding to the multiple correlation evaluation coefficients greater than the correlation evaluation coefficient threshold are screened out to obtain the multiple correlation evaluation results. The multiple correlation evaluation results are then subjected to feature fusion. The feature fusion refers to collecting the most different feature information in the correlation evaluation results to generate new fusion features to obtain the correlation analysis results. By performing feature fusion on multiple correlation evaluation results, the most distinctive feature information can be obtained from the multiple correlation evaluation results, and redundant information generated by the correlation between different feature sets can be eliminated, thereby improving the efficiency of obtaining correlation analysis results.

[0051] Step S400: obtaining an actual performance reliability prediction result based on the correlation analysis result and the performance calculation result;

[0052] In one embodiment, step S400 of the present application further includes:

[0053] Step S410: extracting features from the correlation analysis results to obtain correlation feature data;

[0054] Step S420: matching the performance calculation results based on the correlation feature data to obtain a performance matching calculation result;

[0055] Step S430: generating the actual performance reliability prediction result according to the performance matching calculation result.

[0056] Specifically, the principal component analysis algorithm is used to extract features from the correlation analysis results. The principal component analysis refers to reducing the dimension of the correlation analysis results, eliminating redundant data while ensuring the amount of information, and obtaining the correlation feature data. Then, the correlation features in the performance calculation results are matched according to the correlation feature data to obtain the performance matching calculation results. Finally, the actual performance reliability prediction results are generated based on the performance matching calculation results. The actual performance reliability prediction results refer to the probability of a future landing accident of the high-profile ski landing gear to be tested, which is obtained based on the performance calculation results. By obtaining the actual performance reliability prediction results, support is provided for the next step of the performance reliability test of the high-profile ski landing gear to be tested, thereby further improving the accuracy of the performance reliability test of the high-profile ski landing gear.

[0057] Step S500: constructing a reliability detection knowledge base, and detecting the performance reliability of the high-profile skid landing gear to be detected based on the reliability detection index, the actual performance reliability prediction result and the reliability detection knowledge base.

[0058] In one embodiment, step S500 of the present application further includes:

[0059] Step S510: performing product type analysis on the high-profile skid landing gear to be inspected to obtain a product type analysis result;

[0060] Step S520: obtaining a first performance reliability testing solution based on the product type analysis result and the reliability testing knowledge base;

[0061] Step S530: The performance reliability of the high-profile skid landing gear to be tested is tested item by item according to the first performance reliability testing scheme, the reliability testing index, and the actual performance reliability prediction result.

[0062] Specifically, a reliability testing knowledge base is constructed based on big data technology. The reliability testing knowledge base includes a series of performance testing-related knowledge, including test items, test procedures, test specifications, and precautions for various types of high-profile skid landing gear performance reliability tests. First, a product type analysis result of the high-profile skid landing gear to be tested is obtained based on the production parameters and instructions of the high-profile skid landing gear to be tested. The product type analysis result includes information such as the production material type, structure type, specifications, and applicable scenarios of the high-profile skid landing gear to be tested. Then, based on the product type analysis result, a test solution is matched within the reliability testing knowledge base to obtain a first performance reliability test solution. The first performance reliability test solution is a performance test solution suitable for the high-profile skid landing gear to be tested, including test items, test procedures, test specifications, and precautions. Finally, the performance reliability of the high-profile skid landing gear to be tested is tested item by item based on the first performance reliability test solution. The reliability test indicators and the actual performance reliability prediction results are used to judge and adjust the performance reliability test results of the high-profile skid landing gear to be tested, thereby obtaining a performance reliability test result. This solves the technical problem of low accuracy in reliability testing of high-profile skid landing gear performance. It improves the accuracy of reliability testing of high-profile skid landing gear performance, ensuring the stability of high-profile skid landing gear performance, thereby further ensuring the personal safety of the helicopter and crew.
