[0029] The present utility model will be described in detail below in conjunction with the accompanying drawings, and the features of the present utility model will be further revealed in the following specific description.
[0030] Figure 1 Schematic diagram of an aircraft cable sway arc simulation device 100 according to one aspect of the present utility model is illustrated. In the present utility model, the aircraft cable sway arc simulation device 100 can be used to simulate the arc scenario of a short circuit occurring after the cable sways and touches the surrounding metal structure or pipeline. As Figure 1As shown in the figure, the aircraft cable swinging arc simulation device 100 may include a base 102 and a vertical plate 101 placed on the base. In one embodiment, two long slots may be opened on both sides of the vertical plate 101, and the cable fixing point 104 may move up and down along the long slots to adjust the swinging amplitude and the speed at which the cable collides with the collision object. In yet another embodiment, the long slots may be provided with scales 109 to mark the position of the cable fixing point 104.
[0031] The aircraft cable swinging arc simulation device 100 may further include an inclination adjustment knob 107. In one embodiment, the base 102 and the vertical plate 101 may adjust the angle at which they intersect through the inclination adjustment knob 107 to adjust the swinging amplitude and the speed of collision between the test cable 106 and the collision object 108.
[0032] The aircraft cable swinging arc simulation device 100 may further include a collision object buckle 103 (for example, a collision object fixing buckle). The collision object fixing buckle may be provided on the vertical plate 101 for fixing the collision object 108.
[0033] The aircraft cable swinging arc simulation device 100 may further include a collision object 108, which is fixed to the vertical plate 101 through the collision object fixing buckle. The collision object 108 may be pipes or bars of different sizes fixed as needed. The collision object 108 may be made of metal. The collision object 108 may also be made of non-metal. The size of the collision object 108 may be close to the length of the vertical plate to ensure that the test cable 106 can always contact the collision object 108 during the swinging process. During the swinging arc simulation process, the collision object 108 may be grounded.
[0034] The aircraft cable swinging arc simulation device 100 may further include a cable fixing point adjustment component. The cable fixing point adjustment component may include a cable towing rope 105 and a cable fixing adjustment point 104, which are used to connect and fix the test cable 106 to the vertical plate 101.
[0035] The aircraft cable swinging arc simulation device 100 may further include a test cable 106. The test cable 106 is tied to the cable fixing adjustment point 104 on the vertical plate 101 through the cable towing rope 105. When the test cable is lowered from a high place, a part of the test cable may touch the collision object, and the insulation skin of this part of the test cable is stripped off. During the swinging arc simulation process, the test cable 106 may be energized, and the part of the test cable where the insulation skin is stripped off touches the collision object 108 to trigger a fault arc. By moving the position of the cable fixing adjustment point 104 along the long slot on the vertical plate 101, the height of the test cable 106 relative to the base 102 can be adjusted, thereby adjusting the swinging amplitude and the speed of collision between the cable and the collision object.
[0036] Figure 2 Schematic diagram of the tilt adjustment knob 200 of the aircraft cable swing arc simulation device according to an embodiment of the present utility model. As Figure 2 shown, in another embodiment, the tilt adjustment knob 200 may be provided with a scale pointer 202 to indicate the angle between the base and the vertical plate. The rotating support rod 201 on the tilt adjustment knob 200 can rotate, and the scale pointer 202 can point to different positions on the scale disk 203 to indicate different included angle degrees between the base and the vertical plate. The included angle degree between the base and the vertical plate can be between 0 degrees and 90 degrees. When the included angle between the base and the vertical plate is smaller (i.e., closer to 0 degrees), the included angle at which the test cable collides with the collision object is larger, the swing amplitude is larger, and the speed at which the cable collides with the collision object is slower. Conversely, when the included angle between the base and the vertical plate is larger (i.e., closer to 90 degrees), the included angle at which the test cable collides with the collision object is smaller, the swing amplitude is smaller, and the speed at which the cable collides with the collision object is faster.
[0037] Combined with Figure 1 and Figure 2 The described aircraft cable swing arc simulation device can simulate the scenario where an arc is triggered after the aircraft cable swings and collides with the aircraft metal structure and pipelines, so as to judge the damage conditions of the arc to the cable, metal structure, and pipelines.

After the vibration table 310 is turned on, it drives the base 309 on the vibration table 310 and the related components fixed on the base to vibrate together.
[0039] The aircraft cable vibration arc simulation device 300 may further include a vibration object fixing component. The vibration object fixing component may be T - shaped. The upper half of it is for the vibration object to be fixed thereto by tying, and the lower half may be a hollow round rod 303 and a rotating support rod 304. The rotating support rod 304 can be fixed to the base 309 by screws. The rotating support rod 304 can drive the hollow round rod 303 to rotate 360 degrees around the axis for fixation.
[0040] The aircraft cable vibration arc simulation device 300 may further include a vibration object 302. The vibration object 302 is tied and fixed to the upper half of the vibration object fixing component. The vibration object 302 can be made of metal. The vibration object 302 can also be made of non-metal. The size of the vibration object 302 can be selected according to the simulation purpose. During the vibration arc simulation, the vibration object 302 can be grounded.
[0041] The aircraft cable vibration arc simulation device 300 may further include a cable fixing component 307. The cable fixing component 307 can be T-shaped, and clamps can be fixed at both upper ends thereof for fixing the test cable 301, and a long groove can be opened at the lower part.
[0042] The aircraft cable vibration arc simulation device 300 may further include a height adjustment component 308. The lower end of the height adjustment component 308 is fixed to the base 309, and the upper end is connected to the cable fixing component 307. The height adjustment component 308 can be provided with a long groove. The height adjustment component 308 can be connected to the cable fixing component 307 by screws and nuts. The position of the fixing screw between the height adjustment component 308 and the cable fixing component 307 can be adjusted to adjust the distance between the test cable 301 and the vibration object 302, simulating the real space isolation on the aircraft for multiple groups of simulations.
[0043] The aircraft cable vibration arc simulation device 300 may further include a test cable 301. The test cable 301 is fixed to the cable fixing component 307 through a cable bracket 306 (such as a clamp). During the vibration arc simulation, the test cable 301 can be energized. In the case of vibration, a part of the test cable 301 can touch the vibration object 302, and the insulation of this part of the test cable 301 is stripped off. Due to the intermittent high-frequency contact between the stripped insulation part of the test cable and the vibration object, a short circuit is formed, thus triggering a fault arc.
[0044] Figure 4 The schematic diagram of the base 400 of the aircraft cable vibration arc simulation device according to an embodiment of the present invention is illustrated. As Figure 4 shown, in another embodiment, the base 400 can be provided with a scale pointer 403. The rotating support rod 401 connected to the base 400 can rotate, and the scale pointer 403 can correspondingly point to different positions on the scale disk 402. By rotating the rotating support rod 401, the included angle between the vibration object and the test cable can be adjusted to simulate the vibration arcs in various orientations in reality. The included angle between the vibration object and the test cable can vary between 0 degrees and 180 degrees for multiple groups of simulations at different angles.
[0045] Combined with Figure 3 and Figure 4The described aircraft cable vibration arc simulation device can simulate the scenario where an aircraft cable vibrates and collides with the aircraft's metal structure and pipelines, triggering an arc, thereby determining the damage to the cable, metal structure, and pipelines caused by the arc.
