Abstract
Description
Technical Field
[0001] This invention belongs to the field of integrated assembly and adjustment technology of aircraft system piping, specifically a dynamic clearance measurement system and method for aircraft system piping. Background Technology
[0002] After the aircraft system piping is assembled, the clearances between the pipes and between the pipes and surrounding system components must be checked. This is because when the aircraft is in flight, due to its high speed and large vibrations, the system piping will sway and undergo small displacements. If the static clearance after installation is not greater than the positional offset during flight, it will cause interference between the system piping and surrounding components during flight, leading to malfunctions such as pipe breakage and damage to surrounding components, which will seriously affect the aircraft's flight performance and safety. Therefore, checking the clearances after the system piping is assembled is particularly important.
[0003] Generally, clearances can be divided into static clearances and dynamic clearances. Static clearances refer to the clearances between system pipes or between system management and surrounding system components when the system is stationary. Because the component being inspected is stationary, it can be measured using a feeler gauge, standard gauge block, or vernier caliper. Due to the ease of measurement, repeated measurements are possible, resulting in accurate and verifiable results. Dynamic clearances, on the other hand, refer to the clearances between system pipes or between system management and surrounding system components when they are in motion. Because the component being inspected is in motion, it is difficult to measure during inspection. Current inspection methods involve manually controlling the motion, reducing the speed of the moving component within a feasible range, and then using the same tools used for static clearance inspection throughout the entire stroke of the movement. This involves manually dividing the dynamic clearance into several static clearance positions for inspection.
[0004] The aforementioned method for determining dynamic clearance in the system piping has the following problems: First, manually controlling the movement of moving parts can only be achieved by controlling the aircraft's operating pressure. Since the hydraulic pressure is established non-linearly, the control process itself cannot be linear, affecting the clearance measurement results. Second, when manually dividing the dynamic clearance into several static clearance positions, it is impossible to accurately determine which dividing point is the minimum clearance point, resulting in inaccurate measurement results and only approximate values. Finally, the measurement area is the dynamic system piping movement area. After manually controlling the pressure to stop it, if the system malfunctions or pressure control fails, causing the dynamic system piping to move, safety accidents such as injury to the inspectors may occur when personnel enter this area to measure the clearance.
[0005] Given the above reasons, it is urgent to solve the problem of how to efficiently and accurately measure dynamic gaps after the assembly of aircraft system piping. Summary of the Invention
[0006] To address the aforementioned issues, this invention provides a dynamic clearance measurement system and method for aircraft system piping. Based on an efficient and high-precision image acquisition method for aircraft dynamic system piping, it enables the analysis of the actual state of aircraft moving piping, thereby achieving accurate measurement of dynamic clearance in aircraft system piping.
[0007] The technical solution of the present invention is as follows:
[0008] A dynamic clearance measurement system for aircraft system piping includes a processor, a data storage module, a dynamic system piping visual analysis module, a dynamic system piping information feedback module, and a monitoring terminal. The processor is communicatively connected to the data storage module, the dynamic system piping visual analysis module, and the dynamic system piping information feedback module. The processor is also communicatively connected to visual inspection devices corresponding to each group of dynamic system piping and surrounding system components, and to the monitoring terminal. The corresponding visual inspection devices measure the area where the dynamic system piping is located, and send the image information of the dynamic system piping and surrounding system components to the dynamic system piping visual analysis module via the processor. The dynamic system piping visual analysis module performs visual analysis of the dynamic system piping, determining the motion state of each dynamic system piping, i.e., whether the system piping is in motion or stationary. During motion, it determines the minimum clearance value and compares it against a pre-set standard range to determine if it meets the requirements, marking the corresponding dynamic system piping as qualified. The processor identifies either a dynamic system pipeline or a non-compliant dynamic system pipeline, and then sends the dynamic system pipeline marking information to the processor. Upon receiving the marking information, the processor generates corresponding control commands and sends them to the corresponding vision inspection device. The vision inspection device displays the measurement results on the monitor, providing the operator with non-compliance information. The operator then troubleshoots the problem on the machine based on the non-compliance information and performs another measurement. After the measurement of the corresponding dynamic system pipeline on the corresponding vision inspection device is completed, the processor generates an information feedback analysis signal and sends it to the dynamic system pipeline information feedback module. Upon receiving the dynamic system pipeline information feedback signal, the dynamic system pipeline information feedback module performs information feedback analysis on the corresponding dynamic system pipeline on the corresponding vision inspection device. Through information feedback analysis, it marks the corresponding dynamic system pipeline on the corresponding vision inspection device as a compliant or non-compliant dynamic system pipeline and sends the relevant information to the processor. The data storage module stores the data in the processor.
[0009] The specific operation process of the dynamic system pipeline visual analysis module is as follows: It acquires and determines the image measurement information of the dynamic system pipeline and surrounding system components in the detection area, and calculates the gap values at all times, based on the following calculation principles:
[0010] 1) Define the spatial location model of the pipeline in the dynamic system under test. for:

[0013] 2) Similarly, the spatial location model of the components of the surrounding system being measured. for:
[0014]
[0015] in, For the horizontal coordinates of the surrounding system components; For the longitudinal coordinates of the surrounding system components; , indicating the height of the surrounding system components.
[0016] 3) For the pipeline of the dynamic system under test, it can be represented by a six-degree-of-freedom vector in the test space as follows:
[0017]
[0018] in, , , The coordinates of the measurement point at time t in the pipeline of the dynamic system under test; , , These represent the inclination angles of the pipeline of the dynamic system under test at time t relative to the spatial coordinate axes x, y, and z.
[0019] 4) The trajectory of motion is within a time period Let the integral of the measured dynamic system pipeline be the rate function per second. The trajectory of the pipeline in the dynamic system under test for:
[0020]
[0021] 5) Similarly, for peripheral system components, they can be represented by a six-degree-of-freedom vector in the measured space as follows:
[0022]
[0023] in, , , Let t be the coordinates of the measurement points of the surrounding system components; , , , respectively, are the inclination angles relative to the spatial coordinate axes x, y, and z at time t.
[0024] 6) The trajectory of motion is within a time period Let the integral be the rate function per second of the peripheral system components. The movement trajectory of the surrounding system components for:
[0025] =
[0026] 7) The difference between the motion trajectory of the pipeline in the tested dynamic system and the motion trajectory of the surrounding system components. The gap between the two:
[0027]
[0028] 8) Based on different gap value requirements, different allowable ranges are set, and the dynamic system pipeline visual analysis module automatically determines whether the simulation meets the requirements within the allowable tolerance range.
[0029] The analysis and determination of gap values between dynamic system pipelines and multiple peripheral system components under simultaneous measurement shall be carried out according to the following principles:
[0030] 1) The dynamic system pipeline visual analysis module is designed to simultaneously determine the gap values of multiple measured peripheral system components, and simultaneously receive or send information. The information is actually an analog signal value, which is determined based on the attribute parameters of each sensor and the actual current. The specific formula is as follows:
[0031]
[0032] in, Represents the value of an analog signal; For sensor fixed coefficients; This is the actual current value of the sensor; This is the sensor resistance value; This is the sensor correction voltage value.
[0033] 2) The total data transmission model for multiple tested peripheral system components is as follows:
[0034]
[0035] Where X represents the total amount of data. to These represent the data volume of n peripheral system components being tested.
[0036] 3) The data volume of the tested peripheral system components depends on the data volume of each individual line and the total number of lines. The data volume model is as follows:
[0037]
[0038] in, The amount of data for the components of the surrounding system under test; N represents the data volume of a single line of the peripheral system component under test; N represents the total number of lines of the peripheral system component under test.
[0039]
[0040] in, Fixed parameter coefficients for the components of the surrounding system under test; The amount of data on a single line of the peripheral system component under test at time t. Analog signal value The accumulation is modeled as follows:
[0041]
[0042] in, is the sensor fixation coefficient corresponding to the measured peripheral system component at time t; Let t be the actual sensor current value corresponding to the measured peripheral system component at time t; Let t be the sensor resistance value corresponding to the measured peripheral system component at time t; Let t be the sensor correction voltage value corresponding to the measured peripheral system component at time t.
[0043] 4) Combining the above derived model formulas, the corresponding model formulas for the data volume of the measured peripheral system components, actual current values, and sensors are obtained:
[0044]
[0045] 5) Therefore, the model for the total amount of data transmitted by multiple tested peripheral system components collected by the dynamic system pipeline visual analysis module is as follows:
[0046]
[0047] in, These are the fixed parameter coefficients for n components of the surrounding system under test. Each represents the total number of circuits for n tested peripheral system components; These are the sensor fixation coefficients corresponding to the n measured peripheral system components at time t; These are the actual sensor current values corresponding to the n measured peripheral system components at time t; These are the sensor resistance values corresponding to the n measured peripheral system components at time t; These are the sensor correction voltage values corresponding to the n measured peripheral system components at time t.
[0048] The dynamic system pipeline visual analysis module receives information simultaneously from multiple tested peripheral system components. In this case, it is crucial for the dynamic system pipeline visual analysis module to determine and analyze the source of the received information. If it cannot accurately analyze and determine the source, it may be impossible to determine the minimum gap value or the determination may be inaccurate. Therefore, the total data volume model is specified to take the minimum value of the data volume of multiple tested peripheral system components to determine the location of the minimum gap value and output the minimum gap value.
[0049] A method for measuring dynamic clearances in aircraft system piping, employing the aforementioned measurement system, comprises the following specific steps:
[0050] S1. Use visual inspection equipment to measure and image the moving area of the dynamic system pipeline, and send the image information of the dynamic system pipeline and surrounding system components to the dynamic system pipeline visual analysis module via the processor.

[0052] S3. After receiving the dynamic system pipeline marking information, the processor sends the corresponding control command to the corresponding vision inspection device. The vision inspection device displays the measurement results on the display and provides the operator with non-compliance information.
[0053] S4. The operator can troubleshoot the problem on the machine based on the non-conforming information, and then measure again;
[0054] S5. After all measurements are completed, the processor will send the received dynamic system pipeline measured gap value information to the monitoring terminal for viewing, storage and output of the measurement technical report.
[0055] The beneficial effects of this invention are:

The visual inspection device displays the measurement results on the display and provides the operator with the option to manually check the unqualified pipeline again. This helps the operator to manually select to measure again, avoid measurement errors, and ensure measurement quality.

The results are visualized and the measurement information is sent to the corresponding supervision terminal through the processor, which facilitates the selection of visual inspection equipment by the staff and helps the staff to carry out targeted supervision and maintenance of different dynamic system pipelines.

[0070] S5. After all measurements are completed, the processor will send the received dynamic system pipeline measurement information to the monitoring terminal for viewing / storage and output of the measurement technical report.
[0071] In this embodiment, the analysis and determination of the gap values of the dynamic system pipeline and five peripheral system components under test are simultaneously measured according to the following principles:
[0072] 1) The dynamic system pipeline visual analysis module is designed to simultaneously determine the gap value of multiple measured peripheral system components. Taking five measured peripheral system components as an example, information is received or sent simultaneously. The information is actually an analog signal value, which is determined based on the attribute parameters of each sensor and the actual current. The specific formula is as follows:
[0073]
[0074] in, Represents the value of an analog signal; The sensor is fixed, and in this embodiment, the value is (1, 5). This is the actual current value; This is the sensor resistance value; This is the sensor correction voltage value.
[0075] 2) The total data transmission model for the five tested peripheral system components is as follows:
[0076]
[0077] Where X represents the total amount of data. to These represent the data volume of five tested peripheral system components.
[0078] 3) Taking the first tested peripheral system component information receiving device as an example, its data volume depends on the data volume of its single line and the total number of lines. The data volume model is as follows:
[0079]
[0080] in, This represents the data volume of the first tested peripheral system component; N represents the data volume of a single line of the first tested peripheral system component; N represents the total number of lines of the first tested peripheral system component.
[0081]
[0082] in, The fixed parameter coefficients are those for the first tested peripheral system component. This represents the amount of data on a single line of the first tested peripheral system component at time t. Analog signal value The accumulation is modeled as follows:
[0083]
[0084] 4) Combining the above derived model formulas, the corresponding model formulas for the data quantity of the first measured peripheral system component, the actual current quantity, and the sensor can be obtained:
[0085]
[0086] 5) Therefore, the total data volume model of the five tested peripheral system components collected by the dynamic system pipeline visual analysis module can be processed as follows:
[0087]
[0088] In this embodiment, the specific analysis process of the dynamic system pipeline visual analysis is as follows:
[0089] Step S1: Obtain the dynamic system pipeline number of the vision inspection equipment, and obtain the dynamic system pipeline measurement information obtained by the vision inspection equipment through measurement. The dynamic system pipeline measurement information includes the dynamic system pipeline outline, length, outer diameter, outer nut shape, etc. The above measurement information is marked as TC1, TC2, TC3, and TC4 respectively.
[0090] Step S2: Using the dynamic gap value determination formula of the dynamic system pipeline visual analysis module, for example, by analyzing and calculating the outline TC1 of the system pipeline, the difference between the motion trajectory of the tested dynamic system pipeline and the motion trajectory of the surrounding system components is obtained. :
[0091]
[0092] The component requirements in this embodiment should ensure that The product must satisfy the range [5, +∞). If it does not satisfy this range, mark this position as unqualified. The determination of whether a product is qualified is based on the calculation result; for example, if the result is "5", then for... If the system meets the requirement of being within the range of [5, +∞), the dynamic clearance of the piping is deemed acceptable; if the result is "2", then for... Based on the principle of satisfying the range [5, +∞), the dynamic clearance of the pipeline in this system is deemed unqualified.
[0093] Step S3: If the test result is "2", it proves that there is a defective pipeline. Therefore, according to the system pipeline information displayed on the display, the pipeline is corrected by disassembling and reassembling the pipeline and bending it off the machine. After correction, it is reinstalled on the machine and checked again.
[0094] Step S4: The dynamic system pipeline visual analysis module will receive information simultaneously sent by five tested peripheral system components. In this case, it is particularly important for the dynamic system pipeline visual analysis module to determine and analyze the source of the received information. If it cannot accurately analyze and determine, it will be impossible to determine the minimum gap value or the determination will be inaccurate. Therefore, it is stipulated that the total data model takes the minimum value of the data volume of multiple tested peripheral system components to determine the position of the minimum gap value and output the minimum gap value. For example, the minimum gap value after calibration is "6".
[0095] Step S5: After all measurements are completed, the processor will send the received dynamic system pipeline measurement information to the monitoring terminal for viewing / storage and output of the measurement technical report.
