Technical Field

[0002] At present, there are a large number of steps that require manual operation in the test process of stabilizer trim motors of civil aircraft, which is not only time-consuming, but also prone to operational delays, thus affecting the progress of the entire test process. Different operators may have different operating techniques and strengths, which may lead to large discreteness of test results and make it difficult to ensure the accuracy and consistency of test results. Multiple independent test equipment has not been effectively integrated, and the test methods are relatively independent. There is no overall test solution, and the operating status and performance status of the trim motor during the test cannot be intuitively reflected.

[0003] The existing testing scheme relies on manual operation, which increases the complexity and risk of the operation. During the testing process of the trim motor, it is impossible to quickly and automatically determine whether the trim motor has a major fault. There is no in-depth analysis of the basic performance of the motor. There is a lack of a technical method for monitoring important parameters of the entire process of aircraft stabilizer trim motor testing and intuitively reflecting the motor performance.

[0004] In view of the above problems, effective technical solutions are currently awaited. Summary of the invention

[0072] Among them, the present application obtains the balancing motor test information of a preset time period, extracts the operating parameter monitoring information and the basic performance detection information, extracts the stall torque data and the vibration amplitude data according to the operating parameter monitoring information, compares the stall torque data with the preset stall torque threshold, and determines whether the stall torque of the balancing motor meets the requirements, compares the vibration amplitude data with the preset vibration amplitude threshold, and determines whether the vibration amplitude of the balancing motor meets the requirements, extracts the electrical parameter deviation rate data, the temperature rise rate data and the energy conversion efficiency data according to the basic performance detection information and processes them to obtain the motor performance index, obtains multiple historical motor performance indices corresponding to the preset time period for processing, and obtains the historical motor performance average index, corrects the motor performance index according to the historical motor performance average index through a preset performance evaluation correction model, and obtains the motor performance correction index, which is compared with the preset performance index threshold to determine whether the motor performance meets the requirements. This application not only takes into account key operating parameters such as the motor's stall torque and vibration amplitude, but also covers multiple aspects of the motor's basic performance, such as the electrical parameter deviation rate, temperature rise rate, energy conversion efficiency, etc., so as to comprehensively reflect the overall performance of the motor. The accuracy and reliability of the data are ensured through the balancing motor test information of a preset time period, as well as the operating parameter monitoring information and basic performance detection information extracted using professional equipment and technical means. This application has multiple advantages such as comprehensiveness and accuracy, scientificity and objectivity, efficiency and practicality, as well as preventive and foresightedness, and is of great significance for improving the operating efficiency of the balancing motor, extending its service life, and reducing maintenance costs.

[0073] Please refer to Figure 2 , Figure 2 The present invention is a flowchart of a method for processing a trim motor test of an aircraft stabilizer to determine whether the trim motor stall torque meets the requirements. According to this embodiment, the stall torque data is compared with a preset stall torque threshold to determine whether the trim motor stall torque meets the requirements, specifically:

[0074] S201, comparing the stall torque data with a preset first stall torque threshold and a second stall torque threshold, respectively, the first stall torque threshold being less than the second stall torque threshold;

[0075] S202: If the stall torque data is less than the first stall torque threshold, the trim motor torque is too low;

[0076] S203: If the stall torque data is greater than or equal to the first stall torque threshold and less than or equal to the second stall torque threshold, the trim motor torque meets the requirement;

[0077] S204: If the stall torque data is greater than the second stall torque threshold, the trim motor torque is too high.

[0078] Among them, in order to quickly judge the torque capacity of the balancing motor, the stall torque data is compared with the preset first stall torque threshold and the second stall torque threshold respectively. The first stall torque threshold is smaller than the second stall torque threshold. For example, the first stall torque threshold is 150Nm, and the second stall torque threshold is 158Nm. If the stall torque data is smaller than the first stall torque threshold, the torque of the balancing motor is too low, and it is necessary to check whether the motor is aging and whether the power supply system is normal. If the stall torque data is greater than or equal to the first stall torque threshold and less than or equal to the second stall torque threshold, the torque output of the motor is within the preset range, indicating that its performance is stable and meets the requirements. If the stall torque data is greater than the second stall torque threshold, the torque of the balancing motor is too high, and it is necessary to check whether the power supply system and the control system are normal.

[0079] Please refer to Figure 3 , Figure 3 The present invention is a flowchart of a method for processing a trim motor test of an aircraft stabilizer to determine whether the trim motor vibration amplitude meets the requirements. According to this embodiment, the vibration amplitude data is compared with a preset vibration amplitude threshold to determine whether the trim motor vibration amplitude meets the requirements, specifically:

[0080] S301, comparing the vibration amplitude data with a preset vibration amplitude threshold;

[0081] S302, if the vibration amplitude data is greater than or equal to the vibration amplitude threshold, then obtaining vibration amplitude exceeding standard data;

[0082] S303, counting the vibration amplitude exceeding the standard data to obtain the number of exceeding the standard times data;

[0083] S304, comparing the exceeding times data with a preset exceeding times threshold;

[0084] S305: If the exceeding times data is greater than or equal to the exceeding times threshold, the vibration amplitude times of the trim motor are too high and do not meet the requirements.

[0085] Among them, in order to avoid damage to the motor or equipment caused by excessive vibration amplitude, it is judged whether the vibration amplitude of the balancing motor meets the requirements, and the vibration amplitude data is compared with the preset vibration amplitude threshold. If the vibration amplitude data is greater than or equal to the vibration amplitude threshold, the vibration amplitude exceeding standard data is obtained. The vibration amplitude can be measured by a vibration measuring instrument and other equipment, and the vibration amplitude exceeding standard data is counted to obtain the number of exceeding standard times data. The system will count all the data of vibration amplitude exceeding standard to obtain the number of exceeding standard times data, and compare the number of exceeding standard times data with the preset number of exceeding standard times threshold. If the number of exceeding standard times data is greater than or equal to the number of exceeding standard times threshold, the number of times of vibration amplitude of the balancing motor is too high and does not meet the requirements. For example, the number of exceeding standard times data is 6 times, and the number of exceeding standard times threshold is 3 times.

[0086] Please refer to Figure 4 , Figure 4 The present invention is a flowchart of a method for processing a test of an aircraft stabilizer trim motor to obtain a motor performance index. According to this embodiment, the motor performance index is obtained according to the basic performance test information, specifically:

[0087] S401, extracting electrical parameter deviation rate data, temperature rise rate data and energy conversion efficiency data according to the basic performance detection information;

[0088] S402: Process the electrical parameter deviation rate data, the temperature rise rate data, and the energy conversion efficiency data through a preset motor performance evaluation model to obtain a motor performance index.

[0089] Among them, in order to further judge the performance status of the balancing motor, it is necessary to analyze the basic performance data of the motor and reflect it intuitively. According to the basic performance detection information, the electrical parameter deviation rate data, temperature rise rate data and energy conversion efficiency data are extracted. The electrical parameter deviation rate data includes the deviation of parameters such as voltage, current and internal resistance, which can reveal whether the motor has electrical faults, aging or unstable operation. The temperature rise rate data refers to the speed at which the temperature of the motor rises during operation. Excessive temperature rise rate may mean that there is a problem with the cooling system of the motor, or there are friction, short circuit and other faults inside the motor, which need to be inspected and repaired in time. The energy conversion efficiency data refers to the efficiency of the motor in converting the input electrical energy into mechanical energy, which directly reflects the energy efficiency level of the motor. The motor performance index is obtained by processing the electrical parameter deviation rate data, temperature rise rate data and energy conversion efficiency data through the preset motor performance evaluation model. The motor performance index provides us with a concise and clear evaluation result, allowing us to quickly understand the performance status of the motor. By comparing the performance indexes of different motors, we can easily identify motors with better performance; at the same time, by monitoring the changing trend of the performance index, we can also timely discover the performance degradation or potential faults of the motor, providing strong support for the maintenance and optimization of the motor;

[0090] The calculation formula of the motor performance evaluation model is:

[0091]

[0092] Among them, D pa is the motor performance index, e ch 、w ds 、p ca are electrical parameter deviation rate data, temperature rise rate data and energy conversion efficiency data respectively. α, ∈, θ and κ are preset characteristic coefficients, which can be obtained by querying the preset trim motor database.

[0093] Please refer to Figure 5 , Figure 5 The present invention is a flowchart of a method for processing a test of an aircraft stabilizer trim motor to obtain a motor performance correction index. According to this embodiment, the motor performance index is processed in combination with a historical motor performance average index to obtain a motor performance correction index, specifically:

[0094] S501, acquiring a plurality of historical motor performance indexes corresponding to the preset time period;

[0095] S502, performing processing according to the plurality of historical motor performance indexes to obtain a historical motor performance average index;

[0096] S503 , correcting the motor performance index according to the historical motor performance average index by using a preset performance evaluation correction model to obtain a motor performance correction index.

[0097] In order to more accurately analyze and reflect the performance status of the motor, a plurality of historical motor performance indexes corresponding to the preset time period are obtained and processed to obtain a historical motor performance average index, and then the motor performance index is corrected by a preset performance evaluation correction model to obtain a motor performance correction index;

[0098] The calculation formula of the performance evaluation correction model is:

[0099]

[0100] in, is the motor performance correction index, D pa is the motor performance index, D pha is the historical motor performance average index, β, τ is a preset characteristic coefficient, and the characteristic coefficient can be obtained by querying a preset trim motor database.

[0101] In this embodiment, the motor performance correction index is compared with the preset performance index threshold to determine whether the motor performance meets the requirements, specifically:

[0102] Comparing the motor performance correction index with a preset performance index threshold to obtain a performance deviation rate;

[0103] comparing the performance deviation rate with a preset performance deviation rate threshold;

[0104] If the performance deviation rate is less than the performance deviation rate threshold, the motor performance meets the requirements;

[0105] If the performance deviation rate is greater than or equal to the performance deviation rate threshold, the motor performance does not meet the requirements.

[0106] Among them, in order to judge whether the motor performance meets the requirements, the motor performance correction index is compared with the preset performance index threshold to obtain the performance deviation rate. The size of the performance deviation rate directly reflects the degree of deviation between the motor performance and the expected target. The performance deviation rate is compared with the preset performance deviation rate threshold. If the performance deviation rate is less than the performance deviation rate threshold, it means that the motor performance is good and meets the established requirements. If the performance deviation rate is greater than or equal to the performance deviation rate threshold, it means that the motor performance is insufficient and fails to meet the expected standards. We can make objective and accurate judgments on the performance of the motor and provide a strong basis for subsequent maintenance, optimization or replacement decisions. At the same time, it also provides an important reference for us to continuously improve the performance of the motor and enhance the overall efficiency of the equipment.

[0107] According to this embodiment, it also includes:

[0108] Extracting acceleration rate data according to the trim motor operating parameter information;

[0109] Comparing the acceleration rate data with a preset first acceleration rate threshold and a second acceleration rate threshold respectively, the first acceleration rate threshold being smaller than the second acceleration rate threshold;

[0110] If the acceleration rate data is less than the first acceleration rate threshold, the trim motor acceleration rate is too low;

[0111] If the acceleration rate data is greater than or equal to the first acceleration rate threshold and less than or equal to the second acceleration rate threshold, the trim motor acceleration rate meets the requirement;

[0112] If the acceleration rate data is greater than the second acceleration rate threshold, the trim motor acceleration rate is too high.

[0113] Among them, in order to meet the time requirement for the trim motor to reach the rated speed without generating excessive energy consumption and mechanical damage, the acceleration rate data is extracted according to the trim motor operating parameter information, and compared with the preset first acceleration rate threshold and the second acceleration rate threshold respectively. The first acceleration rate threshold is less than the second acceleration rate threshold. If the acceleration rate data is less than the first acceleration rate threshold, the acceleration rate of the trim motor is too low and cannot meet the time requirement for reaching the rated speed. If the acceleration rate data is greater than or equal to the first acceleration rate threshold and less than or equal to the second acceleration rate threshold, it is judged that the acceleration rate of the trim motor meets the requirement and can reach the rated speed within the specified time. If the acceleration rate data is greater than the second acceleration rate threshold, the acceleration rate of the trim motor is too high. Although it can quickly reach the rated speed, it may bring other adverse factors, such as mechanical wear, increased energy consumption, etc.

[0114] According to this embodiment, it also includes:

[0115] Obtain historical trim motor test result information and extract multiple test failure rate data;

[0116] According to the plurality of test failure rate data, obtaining failure rate growth rate data;

[0117] Comparing the unqualified rate growth rate data with a preset growth rate threshold;

[0118] If the failure rate growth rate data is greater than or equal to the growth rate threshold, an in-depth inspection of the trim motor and the corresponding aircraft end is required.

[0119] Among them, in order to improve the working stability of the trim motor and its compatibility with the aircraft end, the historical trim motor test result information can be obtained through the preset database, and multiple test failure rate data can be extracted, arranged and calculated in chronological order, and the failure rate growth rate data can be obtained, and then compared with the preset growth rate threshold. If the failure rate growth rate data is greater than or equal to the growth rate threshold, it means that the overall performance of the trim motor has declined beyond the requirements, and there may be hidden faults or improper operation, and an in-depth inspection of the trim motor and the corresponding aircraft end is required.

[0120] This embodiment also discloses a processing system for testing an aircraft stabilizer trim motor, including a memory and a processor, wherein the memory includes a processing method program for testing an aircraft stabilizer trim motor, and when the processing method program for testing an aircraft stabilizer trim motor is executed by the processor, the following steps are implemented:

[0126] The motor performance correction index is compared with a preset performance index threshold to determine whether the motor performance meets the requirements.

[0127] According to this embodiment, the stall torque data is compared with a preset stall torque threshold to determine whether the stall torque of the trim motor meets the requirement, specifically:

[0128] comparing the stall torque data with a preset first stall torque threshold and a second stall torque threshold respectively, the first stall torque threshold being less than the second stall torque threshold;

[0129] If the stall torque data is less than the first stall torque threshold, the trim motor torque is too low;

[0130] If the stall torque data is greater than or equal to the first stall torque threshold and less than or equal to the second stall torque threshold, the trim motor torque meets the requirement;

[0131] If the stall torque data is greater than the second stall torque threshold, the trim motor torque is too high.

[0132] Among them, in order to quickly judge the torque capacity of the balancing motor, the stall torque data is compared with the preset first stall torque threshold and the second stall torque threshold respectively. The first stall torque threshold is smaller than the second stall torque threshold. For example, the first stall torque threshold is 150Nm, and the second stall torque threshold is 158Nm. If the stall torque data is smaller than the first stall torque threshold, the torque of the balancing motor is too low, and it is necessary to check whether the motor is aging and whether the power supply system is normal. If the stall torque data is greater than or equal to the first stall torque threshold and less than or equal to the second stall torque threshold, the torque output of the motor is within the preset range, indicating that its performance is stable and meets the requirements. If the stall torque data is greater than the second stall torque threshold, the torque of the balancing motor is too high, and it is necessary to check whether the power supply system and the control system are normal.

[0133] According to this embodiment, the vibration amplitude data is compared with a preset vibration amplitude threshold to determine whether the vibration amplitude of the trim motor meets the requirement, specifically:

[0135] If the vibration amplitude data is greater than or equal to the vibration amplitude threshold, the vibration amplitude exceeding standard data is obtained;

[0136] Counting the vibration amplitude exceeding the standard data to obtain the number of exceeding the standard times data;

[0137] Comparing the exceeding times data with a preset exceeding times threshold;

[0138] If the exceeding times data is greater than or equal to the exceeding times threshold, the vibration amplitude of the trim motor is too high and does not meet the requirements.

[0139] Among them, in order to avoid damage to the motor or equipment caused by excessive vibration amplitude, it is judged whether the vibration amplitude of the balancing motor meets the requirements, and the vibration amplitude data is compared with the preset vibration amplitude threshold. If the vibration amplitude data is greater than or equal to the vibration amplitude threshold, the vibration amplitude exceeding standard data is obtained. The vibration amplitude can be measured by a vibration measuring instrument and other equipment, and the vibration amplitude exceeding standard data is counted to obtain the number of exceeding standard times data. The system will count all the data of vibration amplitude exceeding standard to obtain the number of exceeding standard times data, and compare the number of exceeding standard times data with the preset number of exceeding standard times threshold. If the number of exceeding standard times data is greater than or equal to the number of exceeding standard times threshold, the number of times of vibration amplitude of the balancing motor is too high and does not meet the requirements. For example, the number of exceeding standard times data is 6 times, and the number of exceeding standard times threshold is 3 times.

[0140] According to this embodiment, the motor performance index is obtained according to the basic performance detection information, specifically:

[0141] Extracting electrical parameter deviation rate data, temperature rise rate data and energy conversion efficiency data according to the basic performance detection information;

[0142] The electrical parameter deviation rate data, the temperature rise rate data and the energy conversion efficiency data are processed through a preset motor performance evaluation model to obtain a motor performance index.

[0143] Among them, in order to further judge the performance status of the balancing motor, it is necessary to analyze the basic performance data of the motor and reflect it intuitively. According to the basic performance detection information, the electrical parameter deviation rate data, temperature rise rate data and energy conversion efficiency data are extracted. The electrical parameter deviation rate data includes the deviation of parameters such as voltage, current and internal resistance, which can reveal whether the motor has electrical faults, aging or unstable operation. The temperature rise rate data refers to the speed at which the temperature of the motor rises during operation. Excessive temperature rise rate may mean that there is a problem with the cooling system of the motor, or there are friction, short circuit and other faults inside the motor, which need to be inspected and repaired in time. The energy conversion efficiency data refers to the efficiency of the motor in converting the input electrical energy into mechanical energy, which directly reflects the energy efficiency level of the motor. The motor performance index is obtained by processing the electrical parameter deviation rate data, temperature rise rate data and energy conversion efficiency data through the preset motor performance evaluation model. The motor performance index provides us with a concise and clear evaluation result, allowing us to quickly understand the performance status of the motor. By comparing the performance indexes of different motors, we can easily identify motors with better performance; at the same time, by monitoring the changing trend of the performance index, we can also timely discover the performance degradation or potential faults of the motor, providing strong support for the maintenance and optimization of the motor;

[0144] The calculation formula of the motor performance evaluation model is the aforementioned formula (1).

[0145] According to this embodiment, the motor performance index is processed in combination with the historical motor performance average index to obtain the motor performance correction index, which is specifically:

[0146] Acquire a plurality of historical motor performance indexes corresponding to the preset time period;

[0147] Processing the plurality of historical motor performance indexes to obtain an average historical motor performance index;

[0148] The motor performance index is corrected according to the historical motor performance average index through a preset performance evaluation correction model to obtain a motor performance correction index.

[0149] In order to more accurately analyze and reflect the performance status of the motor, a plurality of historical motor performance indexes corresponding to the preset time period are obtained and processed to obtain a historical motor performance average index, and then the motor performance index is corrected by a preset performance evaluation correction model to obtain a motor performance correction index;

[0150] The calculation formula of the performance evaluation correction model is the aforementioned formula (2).

[0151] According to this embodiment, the motor performance correction index is compared with a preset performance index threshold to determine whether the motor performance meets the requirements, specifically:

[0152] Comparing the motor performance correction index with a preset performance index threshold to obtain a performance deviation rate;

[0153] comparing the performance deviation rate with a preset performance deviation rate threshold;

[0154] If the performance deviation rate is less than the performance deviation rate threshold, the motor performance meets the requirements;

[0155] If the performance deviation rate is greater than or equal to the performance deviation rate threshold, the motor performance does not meet the requirements.

[0156] Among them, in order to judge whether the motor performance meets the requirements, the motor performance correction index is compared with the preset performance index threshold to obtain the performance deviation rate. The size of the performance deviation rate directly reflects the degree of deviation between the motor performance and the expected target. The performance deviation rate is compared with the preset performance deviation rate threshold. If the performance deviation rate is less than the performance deviation rate threshold, it means that the motor performance is good and meets the established requirements. If the performance deviation rate is greater than or equal to the performance deviation rate threshold, it means that the motor performance is insufficient and fails to meet the expected standards. We can make objective and accurate judgments on the performance of the motor and provide a strong basis for subsequent maintenance, optimization or replacement decisions. At the same time, it also provides an important reference for us to continuously improve the performance of the motor and enhance the overall efficiency of the equipment.

[0157] According to this embodiment, it also includes:

[0158] Extracting acceleration rate data according to the trim motor operating parameter information;

[0159] Comparing the acceleration rate data with a preset first acceleration rate threshold and a second acceleration rate threshold respectively, the first acceleration rate threshold being smaller than the second acceleration rate threshold;

[0160] If the acceleration rate data is less than the first acceleration rate threshold, the trim motor acceleration rate is too low;

[0161] If the acceleration rate data is greater than or equal to the first acceleration rate threshold and less than or equal to the second acceleration rate threshold, the trim motor acceleration rate meets the requirement;

[0162] If the acceleration rate data is greater than the second acceleration rate threshold, the trim motor acceleration rate is too high.

[0163] Among them, in order to meet the time requirement for the trim motor to reach the rated speed without generating excessive energy consumption and mechanical damage, the acceleration rate data is extracted according to the trim motor operating parameter information, and compared with the preset first acceleration rate threshold and the second acceleration rate threshold respectively. The first acceleration rate threshold is less than the second acceleration rate threshold. If the acceleration rate data is less than the first acceleration rate threshold, the acceleration rate of the trim motor is too low and cannot meet the time requirement for reaching the rated speed. If the acceleration rate data is greater than or equal to the first acceleration rate threshold and less than or equal to the second acceleration rate threshold, it is judged that the acceleration rate of the trim motor meets the requirement and can reach the rated speed within the specified time. If the acceleration rate data is greater than the second acceleration rate threshold, the acceleration rate of the trim motor is too high. Although it can quickly reach the rated speed, it may bring other adverse factors, such as mechanical wear, increased energy consumption, etc.

[0164] According to this embodiment, it also includes:

[0165] Obtain historical trim motor test result information and extract multiple test failure rate data;

[0166] According to the plurality of test failure rate data, obtaining failure rate growth rate data;

[0167] Comparing the unqualified rate growth rate data with a preset growth rate threshold;

[0168] If the failure rate growth rate data is greater than or equal to the growth rate threshold, an in-depth inspection of the trim motor and the corresponding aircraft end is required.

[0169] Among them, in order to improve the working stability of the trim motor and its compatibility with the aircraft end, the historical trim motor test result information can be obtained through the preset database, and multiple test failure rate data can be extracted, arranged and calculated in chronological order, and the failure rate growth rate data can be obtained, and then compared with the preset growth rate threshold. If the failure rate growth rate data is greater than or equal to the growth rate threshold, it means that the overall performance of the trim motor has declined beyond the requirements, and there may be hidden faults or improper operation, and an in-depth inspection of the trim motor and the corresponding aircraft end is required.
