[0056] In an optional embodiment of the present invention, the swing test device further includes at least one of the following:

[0057] a drive motor, the drive motor being electrically connected to the first swing device or the second swing device;

[0058] The sensor to be tested is fixedly connected to the first surface of the supporting surface 1 .

[0059] In this embodiment, the drive motor provides swinging power to the first swing device or the second swing device to simulate a shaking environment; the drive motor can be connected to the first swing device or the second swing device through a transmission mechanism;

[0060] Here, two drive motors can be provided, which are electrically connected to the first swing device and the second swing device respectively; or one drive motor can be provided. When one drive motor is provided, the swing test device should also be provided with a reversing device, which is provided between the first swing device and the second swing device, and one end of the reversing device is movably connected to the first swing device, and the other end is movably connected to the second swing device. When the swing test is performed, when the drive motor is connected to one of the first swing device and the second swing device and drives the swing device to move, the swing device connected to the drive motor can transmit the driving force provided by the drive motor to the other swing device through the reversing device, thereby realizing the movement of the other swing device, and at the same time reducing the movement cost of the swing device; preferably, the reversing device can be a bevel gear, a worm gear, etc., or other devices that can realize reversing;

[0061] The sensor to be tested is arranged on the first surface of the support surface 1 to collect corresponding data when performing a swing test and analyze the results of the swing test.

[0062] In an implementation example of the present invention, the swing test device may further include: a motor controller electrically connected to the drive motor to control the magnitude and direction of the drive motor voltage and current, thereby changing the rotation rate and rotation direction of the drive motor.

[0063] In an optional embodiment of the present invention, the first swinging device includes:

[0064] At least two first return springs 4; at least two first return springs 4 are symmetrically arranged between the support surface 1 and the support frame 2, and the first ends of the at least two first return springs 4 are fixedly connected to the second surface of the support surface 1, and the second ends are fixedly connected to the first surface of the support frame 2;

[0065] A first rolling device, with both ends of the first rolling device fixedly connected to the second surface of the support surface 1 .

[0066] In this embodiment, Figures 1 to 2As shown, at least two first return springs 4 are symmetrically arranged between the support surface 1 and the support frame 2, and at least two first return springs 4 are fixed on both sides of the support surface 1 and the support frame 2, and are parallel to the first support rod 10 and the second support rod 11, that is, in the two pairs of parallel sides of the support surface 1, one pair of parallel sides is connected to the support frame 2 through the first support rod 10 and the second support rod 11, and the other pair of parallel sides is connected to the support frame 2 through at least two first return springs 4; in this embodiment, six first return springs 4 are provided and evenly distributed on both sides of the support surface 1; of course, the number of first return springs 4 is not limited to 6, and other even numbers sufficient to achieve the shaking of the support surface 1 can also be used;

[0067] The first rolling device is arranged between the support surface 1 and the support frame 2, and is fixedly connected to the second surface of the support surface 1. When performing a swing test, the first rolling device rolls back and forth along the support surface 1 on the horizontal line where the x-axis is located; before performing the swing test, at least two of the first return springs 4 are in a naturally extended state. When performing the swing test, the sensor to be tested placed on the support surface 1 causes at least two of the first return springs 4 to be in a compressed state, and at the same time starts and controls the first rolling device. The first rolling device rolls back and forth along the support surface 1 on the horizontal line where the x-axis is located. The first return spring 4 in the compressed state recovers its deformation under the action of the rolling force provided by the first rolling device and its own elastic force, thereby driving the support surface 1 to swing back and forth above the support frame 2 along the x-axis direction. The sensor to be tested is arranged on the first surface of the support surface 1, and under the drive of the swing of the support surface 1, the sensor to be tested collects relevant data to realize the simulation of the periodic back and forth swing of the shipborne radar, thereby improving the accuracy of the swing test.

[0068] In an optional embodiment of the present invention, the first rolling device includes:

[0069] a first conveyor belt 7, wherein a first end of the first conveyor belt 7 is fixedly connected to one side of the second surface of the support surface 1, and a second end of the first conveyor belt 7 is fixedly connected to the other side of the second surface of the support surface 1;

[0070] The first rolling wheel 61 is disposed on the first conveyor belt 7 and is movably connected to the first conveyor belt 7 .

[0071] In this embodiment, Figures 1 to 2 As shown, the first rolling wheel 61 is provided on the first transmission belt 7, and the first transmission belt 7 is wound around the first rolling wheel 61;

[0072] The first rolling wheel 61 may be connected to the drive motor. Before the swing test, the first rolling wheel 61 is located in the middle of the first conveyor belt 7. During the swing test, the motor controller controls the voltage and current of the drive motor, thereby changing the rotation speed and direction of the first rolling wheel 61. Driven by the first conveyor belt 7, the rotation speed and direction of the support surface 1 in the x-axis direction are adjusted. When the drive motor drives the first rolling wheel 61 to roll to one side on the first conveyor belt 7, one side of the first rolling wheel 61 reels the first conveyor belt 7, and under the tension of one end of the first conveyor belt 7, the support surface 1 is driven to rotate to one side on the horizontal line where the x-axis is located. At this time, the direction of the voltage and current is changed by the motor controller, so that the support surface 1 can rotate to the other side on the horizontal line where the x-axis is located. During the rotation of the support surface 1, the first return spring 4 will be stretched or compressed. During the process of stretching, compressing and recovering the deformation of the first return spring 4, it plays a role of buffering and reducing vibration, and enables the support surface 1 to rotate back and forth on the horizontal line where the x-axis is located, thereby simulating the environment of the ship's back and forth swaying.

[0073] Furthermore, by controlling the working duration of the drive motor to control the distance that the first rolling wheel 61 rolls on the first conveyor belt 7, the amount of the first rolling wheel 61 throughput of the first conveyor belt 7 can be controlled, and then the angle of the support surface 1 rocking back and forth on the x-axis can be controlled, thereby further improving the diversity of the ship rocking test environment simulation and thus improving the accuracy of the test and evaluation results.

[0074] In an optional embodiment of the present invention, the first rolling device includes:

[0075] a first support shaft 12, the first support shaft 12 being arranged parallel to the second surface of the support surface 1;

[0076] The first coupling 62 is provided on one side of the support surface 1 , and one end of the first coupling 62 is fixedly connected to the first support shaft 12 .

[0077] In this embodiment, Figure 3 and 4As shown, the first support shaft 12 passes through the first support rod 10 or the second support rod 11, and the first support shaft 12 is fixedly connected to one end of the first coupling 62, and the other end of the first coupling 62 is fixedly connected to the drive motor; one end of the first coupling 62 is connected to the drive motor, and when performing a swing test, the voltage and current magnitude and direction of the drive motor are controlled by the motor controller, thereby changing the rotation speed and direction of the first coupling 62, thereby achieving adjustment of the rotation speed and direction of the support surface 1 in the x-axis direction;

[0078] When the motor controller controls the drive motor to rotate clockwise or counterclockwise, the drive motor drives the first coupling 62 to rotate clockwise or counterclockwise, and the clockwise or counterclockwise rotation of the first coupling 62 drives the first support shaft 12 to rotate clockwise or counterclockwise. During the clockwise or counterclockwise rotation of the first support shaft 12, since the support surface 1 is fixedly connected to the first support shaft 12, the support surface 1 will rotate back and forth along the x-axis; during the rotation of the support surface 1, the first return spring 4 will be stretched or compressed. During the stretching, compression and deformation recovery of the first return spring 4, the first return spring 4 plays a role of buffering and vibration reduction, and realizes the back and forth rotation of the support surface 1 on the horizontal line where the x-axis is located, so as to realize the simulation of the periodic back and forth swing test environment of the shipborne radar, thereby improving the accuracy of the swing test;

[0079] Furthermore, by controlling the power of the driving motor, the rotation speed of the first coupling 62 is controlled, thereby achieving control of the shaking speed of the support surface 1 on the horizontal line where the x-axis is located.

[0080] In an optional embodiment of the present invention, the second swing device includes:

[0081] At least two second return springs 5; at least two second return springs 5 ​​are symmetrically arranged in the groove of the first end of the fixing frame 3, and the first ends of the at least two second return springs 5 ​​are fixedly connected to the support frame 2, and the second ends are fixedly connected to the fixing frame 3;

In this embodiment, six second return springs 5 ​​are provided and evenly distributed on both sides of the support surface 1. Of course, the number of second return springs 5 ​​is not limited to six, and any other even number sufficient to enable the support surface 1 to rock may also be provided.

[0084] The second rolling device is disposed between the fixing frame 3 and the support frame 2 and is fixedly connected to both sides of the support frame 2. Before the swing test, at least two of the second return springs 5 ​​are in a naturally extended state. During the swing test, the second rolling device rolls back and forth on the support frame 2 along the horizontal line where the y-axis is located.

[0085] The motor controller controls the voltage, current, and direction of the drive motor to change the speed and direction of rotation of the drive motor and the second rolling device, thereby adjusting the direction and speed of rotation of the support frame 2 in the y-axis direction;

[0086] Specifically: when the second rolling device rolls to the left or right, the second return springs 5 ​​on both sides of the support frame 2 are in a stretched state, and the direction and magnitude of the driving motor voltage and current are controlled by the motor controller to realize the control and adjustment of the direction and speed of rotation of the support frame 2 in the y-axis direction, so as to realize the periodic left and right swing simulation of the shipborne radar, thereby improving the accuracy of the swing test; during the rotation of the support frame 2 in the y-axis direction, the second return spring 5 will be stretched, and play a role of buffering and vibration reduction in the process of the second return spring 5 stretching and recovering the deformation.

[0087] In an optional embodiment of the present invention, the second rolling device includes:

[0088] a second conveyor belt 9, wherein a first end of the second conveyor belt 9 is fixedly connected to one side of the second surface of the support frame 2, and a second end of the second conveyor belt 9 is fixedly connected to the other side of the second surface of the support frame 2;

[0089] The second rolling wheel 81 is disposed on the second conveyor belt 9 and is movably connected to the second conveyor belt 9 .

[0090] In this embodiment, Figures 1 to 2 As shown, the second rolling wheel 81 is provided on the second conveyor belt 9, and the second conveyor belt 9 is wound around the second rolling wheel 81;

[0091] The second rolling wheel 81 can be connected to the driving motor. Before the swing test, the second rolling wheel 81 is in the middle position of the second conveyor belt 9; when the swing test is performed, the voltage, current and direction of the driving motor are controlled by the motor controller, so as to change the rotation speed and direction of the second rolling wheel 81, and the rotation speed and direction of the support frame 2 in the y-axis direction are adjusted under the drive of the second conveyor belt 9; when the driving motor drives the second rolling wheel 81 to roll to one side on the second conveyor belt 9, one side of the second rolling wheel 81 reels the second conveyor belt 9, and drives the support frame 2 to move to one side in the y-axis direction under the tension of the second conveyor belt 9 on this side. When the support frame 2 is rotated to the side, the direction of the voltage and current is changed by the motor controller, so that the support frame 2 can be rotated to the other side in the y-axis direction; during the rotation of the support frame 2, the second return spring 5 will be stretched, and the second return spring 5 plays a role of buffering and reducing vibration during the stretching and recovery process, and the support frame 2 is rotated in the groove of the fixing frame 3 along the horizontal line where the y-axis is located. At this time, since the support surface 1 and the support frame 2 are connected by the first support rod 10 and the second support rod 11, the support surface 1 is driven by the movement of the support frame 2, causing the support surface 1 to rock left and right, so that the support surface 1 rotates back and forth on the horizontal line where the y-axis is located, thereby simulating the left and right rocking environment of the ship.

[0092] Furthermore, by controlling the power of the driving motor to control the distance that the second rolling wheel 81 rolls on the second conveyor belt 9, the amount of the second rolling wheel 81 throughput of the second conveyor belt 9 can be controlled, and then the angle of the support surface 1 rocking back and forth on the horizontal line where the y-axis is located can be controlled, thereby further improving the diversity of the simulation of the ship rocking test environment and thereby improving the accuracy of the test and evaluation results.

[0093] In an optional embodiment of the present invention, the second rolling device includes:

[0094] A second support shaft 13, which is provided through the support frame 2 and is connected to the support frame 2;

[0096] In this embodiment, Figure 3 and 4 As shown, the second support shaft 13 is set through the support frame 2, and the second coupling 82 is fixedly connected to one end of the second support shaft 13;

[0097] One end of the second coupling 82 is connected to the drive motor. When performing a swing test, the drive motor drives the second coupling 82 to rotate clockwise or counterclockwise. The clockwise or counterclockwise rotation of the second coupling 82 drives the second support shaft 13 to rotate clockwise or counterclockwise, and drives the support frame 2 to rotate. At this time, the second return springs 5 ​​on both sides of the support frame 2 are stretched. Furthermore, the direction and magnitude of the voltage and current of the drive motor are controlled by the motor controller to adjust and control the direction and speed of rotation of the support frame 2 in the y-axis direction. During the rotation of the support frame 2, the second return spring 5 is stretched, and plays a buffering and vibration reduction role in the process of stretching and recovering the deformation of the second return spring 5, and realizes the back and forth rotation of the support frame 2 on the horizontal line where the y-axis is located. At this time, since the support surface 1 and the support frame 2 are connected by the first support rod 10 and the second support rod 11, the support surface 1 is driven by the movement of the support frame 2, so as to simulate the periodic left and right swing test environment of the shipborne radar, thereby improving the accuracy of the swing test.

[0098] When performing a swing simulation test, the swing test device provided by the above embodiment of the present invention can be fixedly connected to the vehicle-mounted platform via the fixing bracket 3.

[0102] When conducting a swing simulation test, specifically:

[0103] 1. Back and forth rocking, that is, the first rocking device can control the support surface 1 to periodically rock back and forth along the x-axis on the support frame 2;

[0104] When the first rolling device of the first rocking device includes a first rolling wheel 61 and a first conveyor belt 7: the first rolling wheel 61 is connected to the drive motor through a transmission mechanism, the first rolling wheel 61 rolls and drives the first conveyor belt 7, the first conveyor belt 7 is fixedly connected to the support surface 1, and the support surface 1 swings back and forth around the first support shaft 12, thereby driving the shipborne radar fixed on the support surface 1 to swing back and forth periodically, and the six vertical first return springs 4 play a role in buffering, reducing vibration and restoring during the back and forth swinging process;

[0105] When the first rolling device of the first rocking device includes a first support shaft 12 and a first coupling 62: the first coupling 62 is connected to the driving motor, and the driving motor drives the first coupling 62 to rotate clockwise or counterclockwise around the first support shaft 12, and drives the first support shaft 12 to rotate; during the clockwise or counterclockwise rotation of the first support shaft 12, the support surface 1 compresses the first return spring 4 on one side and stretches the first return spring 4 on the other side; by controlling the direction and magnitude of the voltage and current of the driving motor through the motor controller, the rotation rate and direction of the first coupling 62 can be changed, thereby realizing the adjustment of the rotation rate and direction of the support surface 1 in the x-axis direction.

[0106] During the rotation of the support surface 1, the first return spring 4 will be stretched or compressed. The first return spring 4 plays a role of buffering and vibration reduction during the stretching, compression and deformation recovery process, and enables the support surface 1 to rotate back and forth on the horizontal line where the x-axis is located. The support surface 1 rotates and drives the shipborne radar fixed on the support surface 1 to achieve periodic back and forth swinging.

[0107] 2. Left-right swing, that is, the second swing device can control the support frame 2 to periodically swing left-right along the y-axis direction on the fixing frame 3;

[0108] When the second rolling device of the second rocking device includes a second rolling wheel 81 and a second conveyor belt 9: the second rolling wheel 81 is connected to the drive motor, the second rolling wheel 81 rolls and drives the second conveyor belt 9, the second conveyor belt 9 is fixedly connected to the support frame 2, and the support frame 2 swings left and right around the second support shaft 13, thereby driving the shipborne radar fixed on the support surface 1 to achieve periodic left and right swings. The six horizontal second return springs 5 ​​play a role in buffering, reducing vibration and restoring during the left and right swinging process;

[0109] When the second rolling device of the second rocking device includes a second support shaft 13 and a second coupling 82, the second coupling 82 is connected to the drive motor. The motor controller controls the drive motor to drive the second coupling 82 to rotate clockwise or counterclockwise around the second support shaft 13, thereby driving the second support shaft 13 to rotate clockwise or counterclockwise, and driving the support frame 2 to rotate. At this time, the second return springs 5 ​​on both sides of the support frame 2 are stretched. Furthermore, the motor controller controls the direction and magnitude of the voltage and current of the drive motor to adjust and control the direction and speed of rotation of the support frame 2 in the y-axis direction. During the rotation of the support frame 2, the second return spring 5 is stretched, and plays a buffering and vibration-reducing role during the stretching and deformation recovery process of the second return spring 5, thereby enabling the support frame 2 to rotate back and forth on the horizontal line where the y-axis is located. At this time, since the support surface 1 and the support frame 2 are connected by the first support rod 10 and the second support rod 11, the support surface 1 is driven by the movement of the support frame 2, causing the support surface 1 to shake, thereby driving the support surface 1 and the shipborne radar fixed to the support surface 1 to achieve periodic left and right swing.

[0110] The above-mentioned embodiment of the present invention can provide a fixed position for the sensor to be tested through the arrangement and coordination of the fixing frame 3, the support frame 2 and the support surface 1, thereby ensuring the stability of the sensor to be tested during the swing test, and thus improving the accuracy of the swing test results; through the arrangement of the first swing device and the second swing device that are perpendicular to each other, the periodic swing simulation of the entire swing test device in different directions can be realized, avoiding the risk of actual ship installation and the singleness of the test results caused by the testing of sensor equipment in a laboratory environment being restricted by space and environment, further improving the safety of the test process and the accuracy of the test results; at the same time, the installation and structure of the entire swing device are simple, which reduces the test cost and achieves a high degree of unity between practicality and economy.

[0111] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
