[0021] This utility model provides, for example Figures 1-4The device shown is a performance testing and verification device for an airborne satellite communication terminal mounted on a ship. It includes a test bench 1, a through groove 4 on the top of the test bench 1, and a rubber ring 5 fixedly connected to the inner wall of the through groove 4. The rubber ring 5 can be made of rubber, but is not limited to rubber, and has a certain strength. A ring 6 is fixedly connected to the inner wall of the rubber ring 5, and a fixed disk 7 is rotatably arranged inside the ring 6.

[0022] An annular groove 14 is formed on the inner wall of the ring 6, and an annular plate 15 is rotatably mounted inside the annular groove 14. The annular plate 15 is fixedly connected to the fixed disk 7. In actual use, a structure such as a ball bearing is provided between the annular groove 14 and the annular plate 15 to ensure smooth rotation.

[0023] The top of the fixed plate 7 is provided with a positioning component. Multiple positioning components are provided. The positioning component includes a threaded hole 8 and a bolt 9. The threaded hole 8 is opened on the top of the fixed plate 7, and the bolt 9 is engaged with the threaded hole 8.

[0024] The antenna equipment of the airborne satellite communication terminal is placed on the mounting plate 7, and the antenna equipment is fixed on the mounting plate 7 by the cooperation of the bolt 9 and the threaded hole 8.

[0025] Because of the rubber ring 5, the fixed plate 7 and the ring 6 can swing, simulating the swaying environment of a ship sailing at sea, to check whether the antenna equipment is structurally sound and whether its performance is stable.

[0026] A wind power assembly for testing is set above the test bench 1. The wind power assembly includes a bracket 2 and a fan 3. The bracket 2 is fixedly connected to the top of the test bench 1, and the fan 3 is installed on the bracket 2. The fan 3 is connected to the factory power supply, and the wind power of the fan 3 is adjustable. When the fan 3 is running, it blows air towards the antenna equipment to simulate the wind environment when a ship is sailing at sea and to check the wind resistance of the antenna equipment.

[0027] The test bench 1 is equipped with a drive assembly for rotating the fixed disk 7. The drive assembly includes a motor 10, a rotating shaft 11, a vertical plate 12, and a rotating plate 13. The motor 10 is fixedly connected to the upper surface of the bottom of the test bench 1, the rotating shaft 11 is fixedly connected to the drive shaft of the motor 10, the vertical plate 12 is fixedly connected to the top of the rotating shaft 11, the bottom end of the rotating plate 13 is hinged to the vertical plate 12, and the top end of the vertical plate 12 is fixedly connected to the fixed disk 7.

[0028] In actual use, the motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the fixed disk 7 to rotate on the ring 6 through the vertical plate 12 and the rotating plate 13, so that the wind force blown by the fan 3 can act on different positions of the antenna equipment, simulating the wind force that a ship will experience in different directions when sailing at sea.

[0029] The test bench 1 is internally equipped with a control assembly for driving the fixed disk 7 to swing. The control assembly includes a fixed frame 16 and an electric push rod 17. The fixed frame 16 is fixedly connected to the rotating shaft 11. The fixed end of the electric push rod 17 is hinged to the top of the fixed frame 16, and the telescopic end of the electric push rod 17 is hinged to the fixed disk 7. The control assembly corresponds to the swing direction of the rotating plate 13, as shown in the reference. Figure 4 The rotating plate 13 can swing left and right, and the control component is installed on the left or right side of the rotating plate 13. When the motor 10 drives the rotating shaft 11 to rotate, the control component rotates synchronously.

[0030] Both the electric actuator 17 and the motor 10 are connected to the factory's power supply.

[0031] Reference Figure 3 , Figure 4 As shown, when the telescopic end of the control electric push rod 17 extends, it causes the right side of the fixed plate 7 to swing upward and the left side to swing downward; when the telescopic end of the control electric push rod 17 retracts, it causes the right side of the fixed plate 7 to swing downward and the left side to swing upward, thereby simulating the swaying environment of a ship sailing at sea, and the swaying amplitude is adjustable.

[0032] Furthermore, it can be used in combination with swaying and windy environments.

[0033] This utility model, by setting up a fixed disk 7, a wind power component, and a control component, can simultaneously simulate a swaying environment and a wind power environment, and can also simulate the wind force from different directions that a ship experiences while sailing at sea, thereby improving the efficiency of performance testing and verification of airborne satellite communication terminals.
