Abstract
Description
Technical Field
[0001] The present application relates to the technical field of aviation seat testing, and in particular to an aviation seat dynamic impact automatic deformation testing platform. Background Art
[0002] Passenger seats are one of the main onboard equipment of commuter aircraft. After passengers enter the cabin, most of their activities take place in the seats. Seats play a vital role in the comfort and safety of passengers in the cabin. Passenger seats are not only an indispensable component of the aircraft, but also directly affect the safety of the cabin in survivable crash accidents. They are the last barrier to protect passengers from fatal injuries. Dynamic impact tests are irreplaceable for the safety assessment of aviation seats. In the existing technology, when conducting dynamic seat impact tests, the seat angle and position are usually adjusted manually. The test conditions are less accurate and the adjustment efficiency is low, which affects the test results, so there is room for improvement. Utility Model Content

[0006] By adopting the above technical solution, the spacing value between the left track fixing tool and the right track fixing tool is set according to the spacing size of the legs of the aviation seat to be tested. Through the external driving mechanism, the left track fixing tool and the right track fixing tool are made to slide on the yaw chassis, so that the spacing between the two is consistent with the spacing of the legs of the aviation seat. The aviation seat to be tested is installed on the deformation tool, and the yaw angle, roll angle and pitch angle of the deformation tool relative to the left track fixing tool and the right track fixing tool are adjusted. After all adjustments are completed, the accelerated impact test bench can be operated to perform a dynamic impact test of the seat, which is recorded by a camera. Compared with the traditional manual adjustment method, the test platform of the present application can realize automatic deformation adjustment of the seat yaw angle in the dynamic impact test, thereby improving the test accuracy and efficiency.
[0007] Optionally, a sliding track is provided on the surface of the yaw chassis, and the sliding track is used to install and adjust the left track fixing tooling and the right track fixing tooling.
[0008] By adopting the above technical solution, the sliding track is provided to adjust the distance between the left track fixing tooling and the right track fixing tooling, thereby improving the applicability of the test platform of this application.
[0009] Optionally, the sliding track is opened in a tic-tac-toe shape.
[0010] By adopting the above technical solution, the sliding track is opened in a crisscross shape, which can realize multi-directional adjustment of the left track fixing tooling and the right track fixing tooling, and can be suitable for testing aviation seats with different chair leg spacing and different configurations.

[0012] By adopting the above technical solution, the arc groove can enable the deformable tooling on the left track fixing tooling to rotate, and at the same time can play a limiting role. The sliding groove can enable the deformable tooling on the right track fixing tooling to slide, thereby facilitating convenient adjustment of the test seat.
[0013] Optionally, the rotation angle of the deformable tooling relative to the left track fixed tooling is 10° clockwise-10° counterclockwise; the sliding angle of the deformable tooling relative to the right track fixed tooling is 10° downward-10° upward.
[0014] By adopting the above technical solution, when conducting horizontal impact tests, the deformation of the floor can be simulated through the deformation fixture. That is, the fixture is used to make the slide rail on one side of the seat pitch down or up 10°, and the slide rail on the other side roll 10° clockwise or counterclockwise. This verifies that although the aircraft and seat have been severely deformed under the action of the impact force, the seat is still connected to the aircraft body, making the dynamic impact test results more accurate.
[0015] Optionally, the yaw chassis is rotatably connected to the bottom of the test bench.
[0016] By adopting the above technical solution, the yaw chassis is rotatably connected to the bottom of the test bench, so that the yaw chassis has the function of realizing 360° rotation. Through this rotation feature, the yaw deformation requirements of the seat to be tested can be achieved, so that the test platform can better simulate dynamic impact and make the test results more accurate.
[0017] Optionally, a seat fixing track is provided on the deformation tooling.
[0018] By adopting the above technical solution and providing a seat fixing track, the seat to be tested can be quickly fixed, thereby effectively improving the efficiency of the entire dynamic impact test.
[0019] Optionally, the bottom of the test bench is made of steel.
[0020] By adopting the above technical solution, the test bench bottom is used to connect the test platform and the impact test bench. The test bench bottom is made of steel material, which makes the test bench bottom have the advantages of high rigidity and high strength, thereby extending the service life of the test bench bottom.

[0022] 1. According to the leg spacing of the aircraft seat to be tested, the spacing between the left and right track fixtures is set. Through an external drive mechanism, the left and right track fixtures are made to slide on the yaw chassis, thereby making the spacing between them consistent with the leg spacing of the aircraft seat. The aircraft seat to be tested is installed on the deformation fixture, and the yaw angle, roll angle, and pitch angle of the deformation fixture relative to the left and right track fixtures are adjusted. After all adjustments are completed, the accelerated impact test bench can be operated to conduct a dynamic impact test of the seat, which is recorded by a camera. Compared with the traditional manual adjustment method, the test platform of the present application can realize automatic deformation adjustment of the seat yaw angle during the dynamic impact test, thereby improving the test accuracy and efficiency.
