Description

Technical Field

[0001] This invention relates to the field of performance testing system technology, and more specifically to a comprehensive test system for performance testing of horizontal stabilizer actuators. Background Technology

[0002] With the rapid development of civil aviation technology, aircraft design and manufacturing are increasingly moving towards higher requirements for safety, reliability, and performance. Aircraft stability and control performance are key factors for safe aircraft operation, and the horizontal stabilizer, as a crucial component of aircraft stability, plays a vital role. The primary function of the horizontal stabilizer is to ensure aircraft stability during flight by adjusting the aircraft's pitch angle, while the actuators, as the driving devices of the horizontal stabilizer, are responsible for adjusting the tail angle, thereby achieving precise control of flight attitude. Performance testing of the horizontal stabilizer actuators is crucial during aircraft research and development and production.

[0003] A test bench for a horizontal stabilizer balancing actuator is disclosed in Chinese patent (publication number: CN115535291A). The test bench is characterized by being used for performance testing of horizontal stabilizer balancing actuators. The test bench includes a test mechanism, a mechanical input unit, a lifting control unit, a center distance measurement unit, a dynamic loading unit, a hydraulic test unit, a measurement and control system unit, and a static loading unit.

[0004] The patent and existing technologies have the following technical problems in practical use: 1. Lack of automated testing capabilities: Although the existing equipment has certain automated testing capabilities, it cannot achieve a completely automated testing process without human intervention after the test begins. During the test, the test must be interrupted, and the test personnel must adjust the equipment to the next test configuration before the next test can be carried out.

[0005] 2. Shortcomings in light load control capability: The existing equipment uses a dual-load cylinder loading system. Under light load conditions, the heavy-load cylinder does not disengage, which significantly affects the actual loading effect and stability of the light load.

[0006] 3. Risks exist in clamping and disassembling the horizontal stabilizer actuator: The existing equipment uses manual hoisting of the horizontal stabilizer actuator, which poses a risk of collision damage during clamping and disassembly.

[0007] 4. Lack of manual drive performance detection: During normal flight, actuators are typically controlled by an automated flight control system (such as an autopilot). However, in certain extreme or emergency situations, the automated flight system may malfunction, requiring the pilot to manually control the aircraft to maintain stability. In such cases, the manual input response performance of the horizontal stabilizer actuators becomes particularly critical. Summary of the Invention

[0008] The purpose of this invention is to provide a comprehensive test system for testing the performance of horizontal stabilizer actuators in order to solve the above problems.

[0013] Furthermore, the lifting clamp includes an upper protective shell rotatably mounted on the bottom of the base frame. An insertion window is provided on the outer side of the upper protective shell. The hydraulic motor oil circuit interface of the horizontal stabilizer actuator is located directly opposite the insertion window. A lower protective shell is provided at the bottom of the upper protective shell. A lifting cylinder is fixedly mounted on the front of the lower protective shell. A telescopic bottom shell is fixedly mounted at the bottom of the telescopic end of the lifting cylinder. The telescopic bottom shell can support the bottom end of the drive screw on the horizontal stabilizer actuator. Four sets of hooks are slidably connected inside the lower protective shell. Hanging grooves are provided inside the hooks. An opening is provided in the lower half of the hanging groove, allowing the actuator nut to enter the hanging groove through the opening.

[0014] Furthermore, a servo motor 2 is fixedly installed on the front of the lower protective shell, and a driving bevel gear is fixedly installed on the output end of the servo motor 2.

[0019] The beneficial effects of this invention are as follows: This invention enables the horizontal stabilizer actuator to be transported in a streamlined manner through a hoisting system, sequentially passing through a hydraulic drive system, a loading system, and a manual drive system. With the addition of hydraulic connection components and hoisting fixtures, it can automatically connect to the testing system. The comprehensive testing system for the horizontal stabilizer actuator can achieve fully automated testing without human intervention, greatly improving production efficiency.

[0020] This invention uses a production line setup to ensure that the horizontal stabilizer actuator can only move to the heavy load position after being removed from the light load, thus ensuring that the two load systems do not interfere with each other.

[0021] The optimized lifting fixture of this invention provides excellent protection for the horizontal stabilizer actuator and facilitates its loading and unloading. At the same time, the dedicated lifting fixture also acts as a load transfer medium, enabling rapid connection with the loading system and manual drive system, resulting in high testing efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] Example 1, as Figures 1-8 As shown, a comprehensive test system for testing the performance of a horizontal stabilizer actuator includes a frame 1, a lifting platform 12 on the left side of the frame 1, a control platform 2 below the lifting platform 12, a hydraulic drive system 3 and a loading system 4 installed sequentially from front to back on the top of the lifting platform 12, a hydraulic connection assembly 5 on the right side of the hydraulic drive system 3, a hoisting system 6 installed on the top of the frame 1, a hoisting clamp 10 below the hoisting system 6, a manual drive system 9 installed at the inner bottom of the frame 1, the manual drive system 9 being located behind the loading system 4, and a displacement velocity detection system 7 and a visual positioning system 8 installed on the inner wall of the frame 1. Control platform 2 includes hardware and control software, used for automatic control of the entire system, data acquisition and analysis, fault diagnosis, process display and generation of test reports; Loading system 4 is used to apply heavy and light loads to horizontal stabilizer actuator 13; The hydraulic drive system 3 is used for hydraulic motor drive control and heavy load loading control on the horizontal stabilizer actuator 13; Hydraulic connection assembly 5 is used to realize the automatic connection and disconnection of pipelines between hydraulic drive system 3 and hydraulic motor; The displacement velocity detection system 7 is used to detect the moving position and velocity of the horizontal stabilizer actuator 13; The visual positioning system 8 is used to detect the ground clearance of the hydraulic motor oil circuit interface on the horizontal stabilizer actuator 13 and the actuator nut 14; The manual drive system 9 is used to test the manual input function of the horizontal stabilizer actuator 13; The lifting clamp 10 is used to protect the horizontal stabilizer actuator 13 and can transmit the load applied by the loading system 4 and the drive provided by the manual drive system 9 to the actuator nut 14.

[0026] Test Procedure: The horizontal stabilizer actuator 13 is hoisted onto the hoisting system 6. Then, the hoisting clamp 10 is attached to the actuator nut 14 of the horizontal stabilizer actuator 13. The hoisting clamp 10 provides protection for the horizontal stabilizer actuator 13. The hoisting system 6 then moves the horizontal stabilizer actuator 13 and the hoisting clamp 10 to the designated position. The displacement speed detection system 7 detects the movement position and speed of the horizontal stabilizer actuator 13, and the vision positioning system 8 detects the hydraulic motor oil circuit interface on the horizontal stabilizer actuator 13. When the horizontal stabilizer actuator 13 moves to the position of the hydraulic drive system 3, based on the feedback from the vision positioning system 8, the control platform 2 controls the lifting platform 12 to rise and fall. The lifting platform 12 aligns the hydraulic connection assembly 5 with the hydraulic motor oil circuit interface. The hydraulic connection assembly 5 connects the oil pipes on the hydraulic drive system 3 to the hydraulic motor oil circuit interface. After connection, the hoisting system 6 moves the horizontal stabilizer actuator 13 to the designated position. The horizontal stabilizer actuator 13 is transported to the loading system station 4, where light and heavy loads are applied sequentially, both on the lifting fixture 10. The lifting fixture 10 enables a quick connection with the actuator nut 14, simulating the load conditions experienced by the horizontal stabilizer actuator 13 during actual operation. After loading, the lifting system 6 transports the horizontal stabilizer actuator 13 to the manual drive system station 9. The manual drive system 9 directly drives the drive screw on the horizontal stabilizer actuator 13 to test the manual input function of the horizontal stabilizer actuator 13, completing the overall test of the horizontal stabilizer actuator 13. After the test, the lifting system 6 transports the horizontal stabilizer actuator 13 back to the hydraulic drive system station 3. The hydraulic connection component 5 separates the oil pipeline from the hydraulic motor oil circuit interface. Then, the horizontal stabilizer actuator 13 is removed from the equipment, and the lifting fixture 10 is disassembled. The entire process is automated, requiring no manual intervention, resulting in high testing efficiency and comprehensive test results.

[0027] In the second embodiment, based on the above embodiment, the loading system 4 is further comprising a heavy-duty hydraulic cylinder 41, a heavy-duty pressure sensor 42, a heavy-duty head 43, a light-duty cylinder 44, a light-duty pressure sensor 45, and a light-duty head 46. The heavy-duty pressure sensor 42 is disposed between the heavy-duty head 43 and the extension / retraction end of the heavy-duty hydraulic cylinder 41, and the light-duty pressure sensor 45 is disposed between the light-duty head 46 and the extension / retraction end of the light-duty cylinder 44.

[0028] The horizontal stabilizer actuator 13 first moves to the position of the light load cylinder 44. The light load cylinder 44 drives the light load head 46 to be inserted into the lifting fixture 10, realizing a quick connection for light load testing. The loading status is fed back through the light load pressure sensor 45. Then, the lifting system 6 transports the horizontal stabilizer actuator 13 to the position of the heavy load hydraulic cylinder 41. The horizontal stabilizer actuator 13 is directly disengaged from the light load cylinder 44 to ensure that the two load systems do not interfere with each other. Then, the heavy load hydraulic cylinder 41 drives the heavy load head 43 to be inserted into the lifting fixture 10, realizing a quick connection for heavy load testing. The loading status is fed back through the light load pressure sensor 45.

[0029] In embodiment three, based on the above embodiments, the hydraulic connection assembly 5 includes a mounting plate 51 fixedly installed on the telescopic end of the light-load cylinder 44. A servo motor 52 is fixedly installed on the side of the mounting plate 51 near the hydraulic drive system 3. A set of driving wheels 53 and two sets of driven wheels 54 are rotatably installed on the other side of the mounting plate 51. The two sets of driven wheels 54 simultaneously mesh with the driving wheels 53. The driving wheels 53 are connected to the output end of the servo motor 52. A connector sleeve 55 is provided on the outer side of the driven wheels 54. The pipe connector on the hydraulic drive system 3 can be inserted into the connector sleeve 55, and the pipe passes through the driven wheels 54 and the mounting plate 51. A hose reel 31 is provided between the hydraulic drive system 3 and the mounting plate 51. The hose reel 31 can reel in or unreel the pipe.

[0030] When the horizontal stabilizer actuator 13 moves to the position of the hydraulic drive system 3, it controls the operation of the light load cylinder 44. At this time, the light load cylinder 44 acts as the extension and retraction drive source of the hydraulic connection assembly 5. Since the hydraulic connection assembly 5 and the loading system 4 are distributed in front and behind, the light load head 46 will not contact the horizontal stabilizer actuator 13, and the two will not affect each other. The light load cylinder 44 drives the mounting plate 51 to extend. The mounting plate 51 drives the oil pipe on the hydraulic drive system 3 to approach the hydraulic motor oil pipe interface. The feedback from the light load pressure sensor 45 can determine whether the oil pipe is pressing against the hydraulic motor oil pipe interface. Then, the servo motor 52 is powered on. The servo motor 52 drives the drive wheel 53 to rotate. The drive wheel 53 drives the driven wheel 54 to rotate. The driven wheel 54 connects the oil pipe to the hydraulic motor oil pipe interface through the connector sleeve 55, realizing automatic connection. When the horizontal stabilizer actuator 13 moves to the loading system 4 position, the hose reel 31 loosens the oil pipeline, allowing the horizontal stabilizer actuator 13 to operate normally. When resetting, the hose reel 31 automatically rewinds the oil pipeline, allowing the connector sleeve 55 to be re-attached to the interface position, thus achieving automatic disassembly of the oil pipeline.

[0031] It should be noted that the hydraulic connection assembly 5 can be set in two sets according to the actual specifications of the horizontal stabilizer actuator 13. For example, the horizontal stabilizer actuator 13 has hydraulic motors on both sides, and the two sets are symmetrically arranged on both sides of the hoisting system 6.

[0032] Example 4, based on the above examples, further includes a hoisting system 6 consisting of a slide rail 61, a slide frame 62, a lead screw nut 63, a lead screw motor 64, and a lead screw 65. An electric lifting hoist 66 is installed at the bottom of the slide frame 62. A base frame 67 is fixedly installed at the bottom end of the steel wire on the electric lifting hoist 66. A lifting device 68 is fixedly installed at the bottom of the base frame 67. A secondary guide rail 69 is provided below the slide rail 61. The base frame 67 is slidably connected in the secondary guide rail 69. The entrance of the secondary guide rail 69 is arranged in a figure-eight shape.

[0033] The slide 62 is driven by the lead screw 65 to slide along the slide rail 61, thereby transporting the horizontal stabilizer actuator 13. The electric lifting hoist 66 is used to hoist the horizontal stabilizer actuator 13. The auxiliary guide rail 69 and the base frame 67 can limit the lifting device 68 of the horizontal stabilizer actuator 13 to prevent the lifting device 68 and the horizontal stabilizer actuator 13 below it from swinging during transportation, thus ensuring stable test transport.

[0034] Example 5, based on the above examples, further includes a lifting clamp 10 comprising an upper protective shell 101 rotatably mounted on the bottom of a base frame 67. An insertion window 103 is provided on the outer side of the upper protective shell 101. The hydraulic motor oil circuit interface of the horizontal stabilizer actuator 13 is located directly opposite the insertion window 103. A lower protective shell 104 is provided at the bottom of the upper protective shell 101. A lifting cylinder 110 is fixedly mounted on the front of the lower protective shell 104. The bottom of the extension / retraction end of the lifting cylinder 110... The lower protective shell 104 is fixedly installed with a telescopic base 105, which can support the bottom end of the drive screw on the horizontal stabilizer actuator 13. Four sets of hanging claws 109 are slidably connected inside the lower protective shell 104. The hanging claws 109 have hanging grooves inside, and the lower half of the hanging groove has an opening. The actuator nut 14 can enter the hanging groove through the opening. Loading grooves 108 are provided on both sides of the lower protective shell 104. The heavy load head 43 and the light load head 46 can be inserted into the loading grooves 108.

[0035] A servo motor 111 is fixedly mounted on the front of the lower protective shell 104. A drive bevel gear 112 is fixedly mounted on the output end of the servo motor 111. A drive shaft 113 is rotatably mounted on the outer side of the lower protective shell 104. A driven bevel gear 114 is fixedly mounted on the outer side of the drive shaft 113. The driven bevel gear 114 meshes with the drive bevel gear 112. Four sets of threaded grooves are opened on the outer side of the drive shaft 113. Two sets of threaded grooves on the same end rotate in opposite directions. Four sets of hooks 109 are threadedly connected to the four sets of threaded grooves respectively.

[0036] A ball bearing 107 is rotatably mounted on the lifting surface of the telescopic base 105. Since the telescopic base 105 is in contact with the drive screw, the ball bearing 107 ensures that the telescopic base 105 does not apply additional load to the drive screw, thus not affecting the subsequent load test results.

[0037] The loading slot 108 is V-shaped, and the insertion ends of the heavy-load head 43 and the light-load head 46 are adapted to the loading slot 108. This design allows the heavy-load head 43 and the light-load head 46 or heavy-load head 43 to be inserted into the loading slot 108 even if there is a slight height difference, reducing the difficulty of loading connection. Simultaneously, the loading force applied by the light-load head 46 or heavy-load head 43 is a horizontal force, which is converted into a vertical load force on the actuator nut 14 through the inclined surface of the loading slot 108. Therefore, a smaller loading force can be converted into a larger load force, broadening the range of drive sources for both light and heavy loads.

[0038] During hoisting: The horizontal stabilizer actuator 13 is hung on the lifting device 68, and the horizontal stabilizer actuator 13 is inserted into the hoisting clamp 10. The hydraulic motor is located in the upper protective shell 101, and the actuator nut 14 is located in the lower protective shell 104. The hydraulic motor oil circuit interface is located at the insertion window 103. The connecting part on the actuator nut 14 enters the hanging groove from the opening below the hanging groove inside the claw 109. Then, the lifting cylinder 110 drives the telescopic base shell 105 to rise. The telescopic base shell 105 supports the bottom end of the drive screw of the horizontal stabilizer actuator 13 from below. After being pushed against the bottom of the drive screw, the telescopic bottom shell 105 applies a downward pulling force to the lower protective shell 104 through the lifting cylinder 110. The connecting parts on the actuator nut 14 are fully inserted into the hanging groove. At the same time, the second servo motor 111 is powered on. The second servo motor 111 drives the transmission shaft 113 to rotate through the driving bevel gear 112 and the driven bevel gear 114. The transmission shaft 113 drives the two hanging claws 109 on the same end to move away from each other through the threaded groove. The hanging claws 109 are engaged with the connecting parts on the actuator nut 14, and the lifting fixture 10 is automatically clamped on the actuator nut 14.

[0039] During loading, the light load head 46 or heavy load head 43 is inserted into the loading slot 108, and the actuator nut 14 is loaded by the lifting fixture 10. It should be noted that during the loading process, the actuator nut 14 is driven by an upward rotation force, so that the load can be stably applied by the claw 109 and the lifting fixture 10. During the load test, the pressure sensor detects data. When the pressure exceeds the threshold, the light load head 46 or heavy load head 43 retracts, and the actuator nut 14 drives the lifting fixture 10 to rise as a whole. By controlling the retraction speed of the light load head 46 or heavy load head 43, it is ensured that the actuator nut 14 is always subjected to the same load when it rotates upward, thereby realizing the load test.

[0040] Example 6, based on the above examples, further includes a manual drive system 9 consisting of a low-speed motor and a drive wheel. A manual transmission wheel 106 is fixedly installed at the bottom of the telescopic base 105. The length of the manual transmission wheel 106 is 20-50cm. The upper protective shell 101 is rotatably installed at the bottom of the base frame 67 via a telescopic connector 102.

[0041] The hoisting system 6 transports the horizontal stabilizer actuator 13 to the manual drive system 9. The manual transmission wheel 106 engages with the drive wheel, first applying a screwing force to the actuator nut 14 through the manual transmission wheel 106 until it reaches the top and the actuator nut 14 can no longer rise. At this point, the manual transmission wheel 106 drives the drive screw on the horizontal stabilizer actuator 13 to rotate through the actuator nut 14, thus achieving manual testing. The manual transmission wheel 106 has sufficient length and will not disengage from the drive wheel, ensuring stable testing.

[0042] By using the telescopic connector 102, the lifting clamp 10 is not affected by the base frame 67 when it rotates up with the actuator nut 14.

[0043] Example 7, based on the above examples, further includes a lifting cylinder 11 and a pneumatic control system installed on the left side of the frame 1. The telescopic end of the lifting cylinder 11 is connected to the lifting platform 12. The pneumatic control system is used for loading control of the light-load cylinder 44 and telescopic control of the lifting cylinder 110 and the lifting cylinder 11.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
