Then, the fan is started to blow air, and at the same time, the elevator body is controlled to rotate by the elevator driving module. At the same time, when the elevator body rotates, the rotating shaft can be driven to rotate by the clamping plate and the rotating frame, thereby driving the pointer to rotate.

At this time, the hydraulic oil in the oil storage pipe 302 can be squeezed, and the friction block 304 is pushed against the side wall of the rotating shaft 16 through the moving rod 303.

[0034] See also Figure 7 The lifting mechanism includes a second connecting block 1001 fixedly connected to the side wall of the connecting frame 301, and the bottom of the second connecting block 1001 is connected to the second moving block 307 through the moving module 1002, and a telescopic mechanism is arranged between the second moving block 307 and the piston 306. The moving module 1002 is a well-known technology in the technical field and is not repeated here. A detection component for detecting the distance of the second moving block 307 is arranged on the top of the piston 306. The second moving block 307 is driven to move downward by the moving module 1002, thereby driving the piston 306 to move downward through the telescopic mechanism.

[0035] See also Figure 7 The telescopic mechanism includes two symmetrically arranged sleeves 401 fixedly connected to the bottom of the second moving block 307, and a sleeve rod 402 is inserted into the sleeve 401. The lower end of the sleeve rod 402 is fixed to the top of the piston 306, and the side wall of each sleeve 401 is sleeved with a second spring 403.

Therefore, during the test, it is convenient to adjust the resistance of the elevator body 1501 when rotating, so that the test is more comprehensive and the test effect is better.

[0037] Working principle: During use, when testing is required, the aircraft body 15 is placed in the cylinder 101 and connected and fixed to the lower end of the mounting rod 11. At the same time, the clamping plate 18 is clamped on the side wall of the elevator body 1501. Then, the fan 102 is started to blow air. At the same time, the elevator body 1501 is controlled to rotate by the elevator drive module. At the same time, when the elevator body 1501 rotates, the rotating shaft 16 can be driven to rotate through the clamping plate 18 and the rotating frame 17, thereby driving the pointer 202 to rotate. At this time, the scale on the arc scale plate 201 indicated by the pointer 202 can be detected by the visual sensor 204, so as to facilitate the test of the range of rotation and the accuracy of the angle control. At the same time, the rotation speed of the pointer 202 is detected by the visual sensor 204, so as to test the response speed. And after the angle rotation is completed, the visual sensor 204 detects whether the pointer 202 swings, so as to test the reliability of the rotation.

[0038] When conducting the test, the motor 802 is started, and the rotation of the motor 802 drives the rotation of the fixed block 801, thereby driving the rotating ring 503 to rotate. When the rubber protrusion 702 abuts against the side wall of the fixed rod 701, it can push the first movable block 505 to move away from the first connecting block 601. At the same time, the first spring 603 is compressed. When the rubber protrusion 702 passes over the fixed rod 701, the first movable block 505 can move and reset under the action of the first spring 603. This reciprocating process can make the first movable block 505 move back and forth, thereby driving the knocking rod 506 to knock and vibrate the side wall of the mounting rod 11 back and forth. In addition, by setting up multiple knocking rods 506, the mounting rod 11 can be knocked and vibrated in multiple directions, and the vibration can be transmitted to the aircraft body 15, thereby simulating the performance of the drive module under extreme vibration conditions, making the test more comprehensive and the test effect better.

[0039] When the elevator body 1501 rotates, it can drive the rotating shaft 16 to rotate synchronously. At the same time, the second moving block 307 is driven to move downward through the moving module 1002, thereby driving the piston 306 to move downward through the telescopic mechanism. At this time, the hydraulic oil in the oil storage pipe 302 can be squeezed, and the friction block 304 is pushed to abut against the side wall of the rotating shaft 16 through the moving rod 303. When the second moving block 307 continues to move downward, the second spring 403 is gradually compressed. At this time, the change in the distance of the second moving block 307 is detected by the distance sensor 902, and the compression amount of the second spring 403 can be determined, and then the friction resistance of the friction block 304 to the rotating shaft 16 can be adjusted and controlled. Therefore, during the test, it is convenient to adjust the resistance of the elevator body 1501 when it rotates, so that the test is more comprehensive and the test effect is better.
