Description

Technical Field

[0001] The present invention relates to the technical field of simulated flight, and in particular to a quick-detachable portable control load test bench and a test method. Background Art

[0002] A quick-detachable portable control load test bench and test method are based on the characteristics of aluminum profile structure. According to different test scenarios, the structural position is changed and the structural modules are installed, making it suitable for control load testing in multiple scenarios.

[0003] China's Civil Aviation Regulations (CCAR) Part 60 classifies simulators into four levels: A, B, C, and D. Level D simulators, as the highest level flight simulators, achieve high-fidelity simulation of aircraft characteristics (aerodynamics, control, vision, sound, etc.). They not only play a key role in pilot training, but also play an important role in aircraft design and testing, and the development of emerging aviation fields.

[0004] As one of the important subsystems of the simulator, the control load system establishes an equivalent model of the aircraft / helicopter flight control system and internal and external force loop control to realistically simulate the static control force-displacement characteristics and dynamic control quality characteristics of the real aircraft, providing pilots with a high-quality flight training experience.

[0005] Therefore, it is necessary to set up a quick-detachable portable control load test bench to provide a diverse and easy-to-operate test environment for the control load system, and provide a basis for the research and development, debugging and testing of high-level control load systems. Summary of the Invention

[0006] The purpose of the present invention is to provide a quick-detachable portable control load test bench and test method. Based on the usage scenario, by designing a quick-detachable portable control load test bench, a test environment is provided for two sets of independent, linked, and universally rotating control loads and one set of control loads as an active test motor exciter to perform automatic testing of dynamic and static characteristics, thereby meeting the research and development, debugging and testing needs of the control load system.

[0007] The objectives of the present invention are achieved through the following technical solutions: a quick-release portable control load test bench includes a test bench, a control load motor, a driver, and a control box. The test bench provides a control load testing environment, enabling independent and linked testing of up to two control load systems. The control load motor serves as an actuator to execute control instructions, the driver controls the motor drive, and the control box issues control instructions and collects sensor signals. The quick-release portable control load test bench and testing method are used for independent, linked, and universal rotation testing of the two control loads, as well as automated dynamic and static characteristic testing of one control load as an active test motor exciter.

[0008] Specifically, the quick-release portable control loading test bench uses 4040 aluminum profiles and is connected by quick-release screws. By turning the quick-release screws, quick disassembly and quick adjustment of the height and position of the control loading motor can be achieved. It can support the installation and testing of up to 2 sets of control loading systems; when installing 2 sets of control loading systems, different specifications of control loading motors can be selected, and the 2 sets of control loading systems share 1 control loading control box.

[0009] Specifically, for the independent testing method of the 2 sets of control loading, the height of the motor mounting bracket of the test bench (101) is adjusted by the quick-release screw (112) to adapt to the installation of 2 control loading motors (108&107) of the same or different specifications. The corresponding-direction joysticks are connected through connecting rods and force sensors, and the control box (110) and their respective drivers (105&106) are connected by cables to form 2 independent control loading systems. By operating the connecting mechanisms (109&104) through the joysticks (102&103), the control loading motors (108&107) are actuated to provide a sense of force at the gripping positions of the testers. The control parameters are viewed through the upper computer to carry out the control loading performance test based on this motor.

[0010] Specifically, for the method of the 2 sets of control loading for combined linkage testing, the height of the motor mounting bracket of the test bench (201) is adjusted by the quick-release screw (212). Two control loading motors (208&207) of the same specification are installed in parallel on both sides of the test bench. The corresponding-direction joysticks are connected through connecting rods and force sensors, and the control box (210) and their respective drivers (205&206) are connected by cables to form a 2-channel soft-linkage control loading system, which are respectively configured as control loading channel 1 and control loading channel 2. By pushing the joysticks (202 / 203) of control loading channel 1 / 2, the motors (207 / 208) of control loading channel 2 / 1 are made to follow through software algorithms, and the control parameters are viewed through the upper computer to achieve the dual-channel linkage function test of the control loading.

[0011] Specifically, for the method of the 2 sets of control loading for universal rotation testing, by adjusting the height and position of the motor mounting bracket of the test bench (301), two control loading motors (303&310) of the same specification are installed crosswise on both sides of the test bench. The position of the joystick (305) is adjusted, and the universal rotation mechanism (306) and the connecting rod mechanisms (304&309) are installed. The rocker arms of the two control loading motors (303&310) are connected. The control box (310) and their respective drivers (307&308) are connected by cables to form a set of control loading system with universal rotation. The joystick (305) is pushed horizontally and vertically to operate the connecting mechanisms (309&304), and then the control loading motors (308&307) are actuated, and the control parameters are viewed through the upper computer to achieve the universal rotation function test of the control loading for 2 channels.

[0012] Specifically, for the method of automatically testing the dynamic and static characteristics of the 1 set of control load as an active test motor exciter, specifically by adjusting the height and position of the motor mounting bracket in the test bench (401), two control load motors (405&409) of the same specification are installed in parallel on one side of the test bench. The rocker arms of the motors (405&409) are connected through connecting rods (407) and bearings (406&408). One of the control load motors (405 / 409) is paired with a control box (404) and a driver (403 / 402) to form 1 set of the measured control load system, and the other control load motor (409 / 405) is paired with the same control box (404) and driver (402 / 403) to form 1 set of active test motor exciters. The active test motor exciters are made to move at a sinusoidal speed, ramp speed, constant speed, etc. through the upper computer software. The rotation of the shaft of the measured control load system motor (405 / 409) is driven through the connecting rod (407) and bearings (406&408), realizing the automatic testing of the dynamic and static characteristics of the control load.
