[0035] It also includes a support frame 5, a first drive component, a mounting frame 6, a second drive component, a fixed frame 7, a detection plate 8, a load simulation component, a terrain simulation component, a road surface simulation component and a mud and sand simulation system; two left-right symmetrical support frames 5 are installed on the adjustment frame 2 through springs; each support frame 5 is provided with a locker 5001; each support frame 5 is movably connected to a mounting frame 6; each support frame 5 is installed with a first drive component; the first drive component is connected to the adjacent mounting frame 6; the mounting frame 6 is driven to rotate by the first drive component; the second drive component is installed on the first fixed frame 3; the second drive component is connected to two left-right symmetrical fixed frames 7; each fixed frame 7 is installed with three pressure sensors 7001; all pressure sensors 7001 on the same fixed frame 7 are connected to a detection plate 8; the shape of the detection plate 8 is set in an inverted U-shaped arc; a load simulation component is installed between the top plate 10 and the first fixed frame 3; a terrain simulation component is connected between the bottom frame 1 and the adjustment frame 2; a road surface simulation component is installed on the adjustment frame 2; and a mud and sand simulation system is installed on the adjustment frame 2.

[0036] The first driving assembly includes a motor 201 ; each support frame 5 is fixedly connected to a motor 201 ; and the output end of each motor 201 is fixedly connected to the adjacent mounting frame 6 .

[0037] The second driving assembly includes an electric control push rod 202 ; two electric control push rods 202 are fixedly connected to the left and right sides of the first fixing frame 3 ; the telescopic ends of the electric control push rods 202 on the same side are fixedly connected to the adjacent fixing frame 7 .

[0038] The load simulation component includes a first hydraulic push rod 203 ; two left-right symmetrical first hydraulic push rods 203 are fixedly connected between the first fixing frame 3 and the top plate 10 .

[0039] The terrain simulation component includes a second hydraulic push rod 205 ; the adjustment frame 2 is configured to be movably connected to the base frame 1 , and four second hydraulic push rods 205 arranged in a rectangular shape are arranged between the base frame 1 and the adjustment frame 2 .

[0040] The road simulation component includes a second fixed frame 301, a top block 302 and a third hydraulic push rod 303; two left-right symmetrical second fixed frames 301 are fixedly connected to the adjustment frame 2; each second fixed frame 301 is connected to two up-and-down symmetrical top blocks 302 through a spring; each second fixed frame 301 is fixedly connected to two up-and-down symmetrical third hydraulic push rods 303.

[0041] The facing sides of the two top blocks 302 on the same second fixing frame 301 are arranged in a concave arc shape, and the surfaces of the top blocks 302 are made of wear-resistant rubber material.

[0042] It also includes rollers 204; each detection plate 8 is rotatably connected to three rollers 204 arranged in a ring shape.

[0043] First, manually fix the support shaft 9001 of the bearing seat 9 on the mounting plate 4 by bolts, and remove the end cover 9003, then control the first hydraulic push rod 203 to shrink, pull the top plate 10 upward, and then lift the first fixing frame 3 upward through the upward top plate 10, so that the center point of the mounting plate 4 is aligned with the center point of the mounting frame 6, and then fix the mounting seat 9002 on the mounting frame 6 by bolts, and then control the first hydraulic push rod 203 to reset, at this time, the weight of the first fixing frame 3 is transferred to the support frame 5 through the bearing seat 9, and then control the electric control push rod 202 to drive the fixing frame 7 and the detection plate 8 move downward until the detection plate 8 is in contact with the surface of the mounting seat 9002 and then stops moving. Based on the view from left to right, the control motor 201 drives the mounting frame 6 to rotate clockwise, thereby driving the mounting seat 9002 to rotate clockwise, and the detection plate 8 is in contact with the mounting seat 9002, so that the displacement generated during the rotation of the mounting seat 9002 is synchronously transmitted to the detection plate 8, and then the displacement of the detection plate 8 is detected by the pressure sensor 7001 of the fixed frame 7, so as to realize the detection of the rotation stability of the mounting seat 9002, thereby simulating the scene of the vehicle in the driving process.

[0044] Since the vehicle is usually loaded with cargo during driving, on this basis, the first hydraulic push rod 203 is controlled to drive the top plate 10 to move downward, so that the shock-absorbing spring between the top plate 10 and the first fixed frame 3 is compressed, and the pressure is transmitted to the first fixed frame 3, and then the pressure is transmitted to the support frame 5 through the bearing seat 9. At the same time, the locker 5001 on the support frame 5 is controlled to lock to prevent the support frame 5 from moving downward. In this process, the first hydraulic push rod 203 is controlled to apply a specific pressure to the first fixed frame 3, so that the bearing seat 9 is under different pressure conditions, which facilitates the detection of the stability of the rotation of the bearing seat 9 under different load conditions and improves the comprehensiveness of the detection data of the bearing seat 9.

[0045] Since aerial platforms and other vehicles usually encounter uphill, downhill and slope terrains during driving, the loads on the bearing seat 9 in different sections are also different. For this reason, by controlling the extended length of the telescopic ends of the four second hydraulic push rods 205, the mounting frame 6, the bearing seat 9 and the detection plate 8 and their connecting parts are adaptively tilted, thereby simulating the vehicle being in uphill, downhill and slope terrains during driving, and realizing the test of the stability of the rotation of the bearing seat 9 of aerial platforms and other vehicles driving on terrains with different slopes. It is explained here that at this time, the first hydraulic push rod 203 still applies rated pressure to the first fixed frame 3, simulating the stability of the rotation of the bearing seat 9 when the vehicle is loaded with goods and driving on uphill, downhill and slope terrains.

[0046] Since the vehicle usually encounters speed bumps and potholes during driving, the bearing seat 9 is subjected to a greater impact. Therefore, when the motor 201 drives the bearing seat 9 to rotate, the locker 5001 of the support frame 5 is first controlled to be unlocked, so that the support frame 5 can move up and down on the adjustment frame 2, and the detection plate 8 is controlled to move upward and disengage from the mounting seat 9002. In addition, initially, the third hydraulic push rod 303 below the mounting frame 6 contacts the corresponding top block 302, and then the telescopic end of the third hydraulic push rod 303 located above the mounting frame 6 is controlled to move back and forth quickly, thereby hitting the mounting frame 6 through the top block 302. After the mounting frame 6 is hit, the support frame 5 and the mounting frame 6 will drive the bearing seat 9 to move downward, and the mounting frame 6 and the top block 302 below are When an impact occurs, the spring between the support frame 5 and the adjusting frame 2 is compressed, and then the spring between the support frame 5 and the adjusting frame 2 is quickly reset, thereby simulating that when the vehicle encounters a pothole, the vehicle wheel hub falls into the pothole, causing the bearing seat 9 to be impacted in a downward direction, and then the detection plate 8 is controlled to move downward to fit with the mounting seat 9002, thereby detecting the running stability performance of the bearing seat 9 when the vehicle wheel hub falls into the pothole, and when the top block 302 impacts the mounting frame 6, the bearing seat 9 drives the first fixing frame 3 to move downward through the mounting plate 4, and the shock-absorbing spring between the top plate 10 and the first fixing frame 3 is adaptively extended and retracted; at the same time, the mounting frame 6 can be impacted multiple times by the third hydraulic push rod 303 and the top block 302 located above the mounting frame 6 to improve the rigor of the detection;

[0047] Furthermore, by controlling the telescopic end of the third hydraulic push rod 303 located below the mounting frame 6 to move back and forth rapidly, the lower top block 302 is caused to collide with the mounting frame 6, thereby simulating that when the vehicle encounters a speed bump, the vehicle wheel hub hits the speed bump and is impacted in an upward direction. Subsequently, the detection plate 8 is controlled to move downward and fit the mounting seat 9002, thereby detecting the operating stability performance of the bearing seat 9 when the vehicle wheel hub encounters the speed bump.

[0048] Since the vehicle usually slows down when encountering potholes and speed bumps, after the mounting frame 6 is hit multiple times by the third hydraulic push rod 303 and the top block 302 located above the mounting frame 6, the top block 302 is pushed toward the side of the mounting frame 6 by controlling the two third hydraulic push rods 303 at the same time, so that the concave arc surface of the top block 302 fits with the surface of the mounting frame 6, and since the surface of the top block 302 is made of wear-resistant rubber material, the resistance to the mounting frame 6 is increased to simulate the brake pads braking the vehicle when the vehicle encounters potholes and speed bumps, thereby simulating the situation when the bearing seat 9 slows down after being impacted, thereby improving the accuracy of the detection result.

[0049] Due to the close fit between the detection plate 8 and the bearing seat 9, the detection plate 8 is easily subjected to greater resistance, which may cause greater wear of the detection plate 8 and increase the measurement data error. For this reason, a roller 204 is provided to replace the detection plate 8 in contact with the bearing seat 9, thereby avoiding wear of the detection plate 8 and reducing the measurement data error. In addition, since the roller 204 is provided to be rotatably connected to the detection plate 8, the friction between the bearing seat 9 and the roller 204 is reduced, thereby reducing the wear of the roller 204.

[0050] Example 2

[0051] On the basis of Example 1, Figure 5-Figure 9 As shown, the sediment simulation system includes a water tank 401, an air pump 402 and a nozzle 404; two left-right symmetrical water tanks 401 are installed on the adjusting frame 2; muddy water is stored in each water tank 401; two left-right symmetrical air pumps 402 are fixedly connected to the adjusting frame 2; a nozzle 404 is fixedly connected to the lower side of each water tank 401; each nozzle 404 is connected to the adjacent air pump 402.

[0052] The sediment simulation system also includes baffles 403 ; each water storage tank 401 is fixedly connected with two baffles 403 which are symmetrical in front and back.

[0053] Two adjacent baffles 403 are arranged to bend toward each other, and the minimum distance between the two adjacent baffles 403 is greater than the diameters of the mounting plate 4 and the bearing seat 9 .

[0054] When a vehicle passes through a pothole, muddy water in the pothole is easily splashed into the connection between the support shaft 9001 and the mounting seat 9002. For this reason, muddy water is stored in the water tank 401. When the simulated vehicle enters the pothole, air is pumped to the nozzle 404 through the air pump 402, and then the third hydraulic push rod 303 and the top block 302 above the mounting frame 6 hit the mounting frame 6 multiple times, so that when the mounting frame 6 moves downward, air is sprayed from the nozzle 404 toward the connection between the support shaft 9001 and the mounting seat 9002, and air is sprayed from the muddy water in the water tank 401, thereby driving the muddy water to spray toward the connection between the support shaft 9001 and the mounting seat 9002, By simulating the situation when the vehicle drives into a pothole and muddy water splashes onto the connection between the support shaft 9001 and the mounting seat 9002, the stability of the operation of the bearing seat 9 when muddy water splashes on the bearing seat 9 is detected. On this basis, the mounting frame 6 is pushed to fit with the top block 302 below by controlling the third hydraulic push rod 303 and the top block 302 above, so that the bearing seat 9 is in contact with the water tank 401. At this time, the connection between the support shaft 9001 and the mounting seat 9002 is immersed in the muddy water in the water tank 401, thereby simulating the situation of the vehicle being stuck in a pothole, and then the stability of the rotation of the bearing seat 9 immersed in muddy water is detected, so as to further make the detection result fit the actual situation.

[0055] When the mounting seat 9002 is immersed in the water tank 401 and rotates, the muddy water attached to the surface of the mounting seat 9002 is easily splashed around as the mounting seat 9002 rotates, and then the splashed muddy water is intercepted by the baffle 403, thereby avoiding the muddy water from splashing out of the water tank 401 and reducing the difficulty of cleaning after detection. Furthermore, two adjacent baffles 403 are arranged to bend toward opposite sides, thereby reducing the distance between the baffle 403 and the surface of the mounting seat 9002, thereby improving the interception effect of the baffle 403, and the minimum spacing between two adjacent baffles 403 is greater than the diameter of the mounting plate 4 and the bearing seat 9, thereby avoiding the mounting seat 9002 and the mounting plate 4 from contacting and wearing the baffle 403.

[0056] Example 3

[0057] On the basis of Example 1 and Example 2, Figure 1 , Fig.10 and Fig.11 As shown, it also includes an air tightness detection system, which includes a slip ring 501 and an air bag 502; each support frame 5 is fixedly connected with a slip ring 501; each slip ring 501 is connected with an adjacent air pump 402; each slip ring 501 is rotatably connected with an adjacent mounting frame 6; each mounting frame 6 is provided with an air transmission channel 6001; each air transmission channel 6001 is connected with an adjacent air pump 402 through the slip ring 501; an air bag 502 is fixedly connected to the inner side of each mounting frame 6; each air bag 502 is connected with an adjacent air transmission channel 6001 via a one-way valve; each air bag 502 is provided with a sealing cover 50201; each sealing cover 50201 is installed with a one-way valve; each sealing cover 50201 is installed with an air pressure sensor.

[0058] The oil seal 9004 is usually used to ensure the sealing of the connection between the support shaft 9001 and the mounting seat 9002, and prevent foreign matter from entering the mounting seat 9002. When the vehicle falls into a pothole, the oil seal 9004 is used to prevent mud and water from entering the mounting seat 9002. For this purpose, the bearing seat 9 described on the left is used as an example for detailed description. The air pump 402 is used to transport air into the slip ring 501, so that the air is transmitted to the air supply channel 6001 of the mounting frame 6, so that the gas enters the airbag 502 through the one-way valve between the airbag 502 and the air supply channel 6001, so that the airbag 502 is inflated and pushes the sealing cover 50201 to move toward the side of the mounting seat 9002, so that the sealing cover 50201 fits with the left side of the mounting seat 9002. At this time, the mounting seat 9 002 forms a sealed state inside, as the air pump 402 continues to deliver air to the slip ring 501, the airbag 502 continues to be inflated, so that the air pressure in the airbag 502 increases to the limit, and the one-way valve on the sealing cover 50201 opens, so that the air flow in the airbag 502 enters the mounting seat 9002. When the one-way valve on the sealing cover 50201 opens, the air pump 402 stops delivering air to the slip ring 501, and the one-way valve on the sealing cover 50201 is closed. At this time, the air pressure sensor arranged on the sealing cover 50201 detects the air pressure change in the mounting seat 9002, thereby detecting whether the inner wall of the mounting seat 9002 is leaking, and then detecting the sealing of the connection between the support shaft 9001 and the mounting seat 9002, thereby improving the comprehensiveness of the detection of the bearing seat 9.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
