Description

Technical Field

[0001] The utility model relates to the technical field of aircraft collision testing, in particular to a collision testing mechanism. Background Art

[0002] During the design process of an aircraft, some aircraft, such as cargo aircraft, need to be dropped from high altitudes, cruise to a designated location, then begin to decelerate and finally land on the ground. Therefore, it is necessary to consider the impact of the impact on the aircraft itself when it touches the ground. In order for the aircraft to be used normally, it is necessary to ensure that all functions of the aircraft are normal after landing.

[0003] Usually, designers will install a buffer energy absorption device on the aircraft to alleviate the impact caused by the aircraft when it touches the ground. In order to verify the feasibility and energy absorption effect of the designed buffer energy absorption device, it is necessary to test the aircraft to verify whether the device is effective.

[0004] During the design and test phase, the aircraft does not need to be dropped from high altitude for realistic simulation; however, in order to obtain the impact data of the aircraft during the development phase, designing a collision test mechanism is an inevitable requirement for the development of aircraft.

[0037] Please refer to Figure 1 and Figure 2 A collision test mechanism includes a tooling frame 1, a support frame, a support frame 3 and a collision test bench 4.

[0038] like Figure 1-Figure 2 As shown, the support frame includes a plurality of first square rectangular tubes 2, and the support frame 3 includes a plurality of second square rectangular tubes 31 and two connecting plates 32;

[0039] A plurality of first square rectangular tubes 2 are divided into two rows and are respectively located on both sides of the top of the tooling frame 1; one end of the plurality of first square tubes is connected to the top of the tooling frame 1, and the other end is respectively connected to the bottom of the second square rectangular tube 31; two connecting plates 32 are arranged at the bottom of the plurality of second square rectangular tubes 31 facing each other, and a connecting space is formed between the two connecting plates 32 for mounting ropes so that the ropes can mount the aircraft; through the support frame composed of the plurality of first square rectangular tubes 2, the support frame 3 is at a certain height from the ground, so that the aircraft can swing to a certain height to better simulate the impact of the aircraft.

[0040] In this embodiment, universal wheels 12 with brake pads are respectively provided at the four corners of the bottom of the tooling frame 1 to facilitate the movement of the collision test mechanism. At the same time, the universal wheels 12 with brake pads can be locked during use to prevent the tooling frame 1 from moving.

[0041] The two rows of first square rectangular tubes 2 are respectively inclined inward from the bottom to the top to form a prism structure with better load-bearing capacity; when the aircraft is mounted between the two connecting plates 32 by ropes, the support frame 3 is better supported by the first square rectangular tubes 2 in the prism structure to ensure the stability of the collision test mechanism.

[0042] The support frame 3 also includes a plurality of third-party rectangular tubes 33, each of which is connected to the bottom of a plurality of second square rectangular tubes 31, and the plurality of third-party rectangular tubes 33 are located on both sides of the two connecting plates 32. When the two connecting plates 32 mount an aircraft through ropes, since the aircraft has a certain weight, the connecting plates 32 mounting the aircraft for a long time will cause the plurality of second square rectangular tubes 31 to bend downward, which may cause safety problems over time. Therefore, by arranging the third-party rectangular tube 33 at the bottom of the second square rectangular tube 31, the third-party rectangular tube 33 can effectively resist the bending of the second square rectangular tube 31, so that the connecting plates 32 mounting the aircraft for a long time will not cause the second square rectangular tube 31 to bend downward.

[0043] Specifically, the first support frame 11 is provided with a plurality of first through holes, the second support frame 311 is provided with a plurality of second through holes, and both ends of the first square rectangular tube 2 are respectively provided with a plurality of third through holes; when the two ends of the first square rectangular tube 2 are fixed on the first support frame 11 and the second support frame 311, the plurality of first through holes and the plurality of second through holes are respectively aligned with the plurality of third through holes; and a plurality of bolts are also included, which respectively pass through the plurality of first through holes and the plurality of third through holes and the plurality of second through holes and the plurality of third through holes to fix the first square rectangular tube 2 with the first support frame 11 and the second support frame 311, thereby ensuring the stability of the connection and realizing the connection between the first square rectangular tube 2 and the tooling frame 1 and the second square rectangular tube 31.

[0044] like Figure 1-Figure 2 As shown, the collision test bench 4 is arranged on the tooling frame 1 and is located on one side of the support frame, so that the aircraft can hit the collision test bench 4 when it swings downward.

[0045] Specifically, the collision test bench 4 includes a bracket 41 and a collision plate 42; the bracket 41 is arranged on the top of the tooling frame 1, and the collision plate 42 is arranged on the bracket 41. When the aircraft swings downward, it hits the collision plate 42, thereby completing a simulated collision test of the aircraft.

[0046] In this embodiment, the bottom of the bracket 41 is a rectangular tube horizontal to the base and has a larger contact area with the top of the base, so that the bracket 41 is more firmly connected to the base, so that the collision test bench 4 can withstand the impact caused by the impact of the aircraft; the top of the bracket 41 is a rectangular tube perpendicular to the base, which is used to connect the collision plate 42; reinforcing ribs are also provided between the bottom and the top of the bracket 41 to increase the strength of the bracket 41, so that the collision test bench 4 can further withstand the impact caused by the impact of the aircraft.

[0047] The working principle of this embodiment is:

[0048] The aircraft is mounted on the support frame 3 by ropes, and after the aircraft is swung backward to a certain height, the aircraft is released. Under the action of gravity, the head of the aircraft hits the collision test bench 4 to obtain the impact data of the aircraft.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
