Description

Technical Field

[0001] This invention relates to the field of underwater vehicle equipment technology, and in particular to a simulated load testing system for underwater vehicles. Background Technology

[0002] When underwater vehicles navigate, they are subjected to the forces of water, which impede their propulsion and rudder, creating torque that is applied to the inner and outer shafts of the propulsion system and the rudder shaft, thus becoming the load on the underwater vehicle's propulsion and rudder. To design propulsion and rudder systems that meet the demands of real underwater navigation, current commercially available testing systems capable of simulating real-world loads during underwater navigation are complex in structure, time-consuming to install, and not sufficiently stable during simulated load testing of underwater vehicles. Summary of the Invention

[0003] In view of this, the present invention proposes a simulated load testing system for underwater vehicles.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A simulated load testing system for an underwater vehicle includes a thruster loading system, a servo loading system, a base plate, and a vehicle mounting device. The base plate, from right to left, is equipped with the vehicle mounting device, the servo loading system, and the thruster loading system. The servo loading system includes a torsion bar spring, a torsion spring adjustment device, a servo clamp, and a mounting device. The mounting device is located on the base plate. Torsion spring adjustment devices are embedded around the inner perimeter of the mounting device, and each torsion spring adjustment device has a torsion bar spring facing inward. Each torsion bar spring has a servo clamp at its end. The thruster loading system includes a magnetic powder brake, a brake control device, a brake mounting device, a coupling, and a bevel gear. The base plate has two brake mounting devices, each with a magnetic powder brake positioned horizontally and vertically. The right end of the horizontally positioned magnetic powder brake is connected to the coupling, and the front end of the vertically positioned magnetic powder brake is connected to the bevel gear. The brake control device is electrically connected to the two magnetic powder brakes.

[0006] Preferably, there are two aircraft fixing devices, which are arranged side by side and parallel on the base plate.

[0007] Preferably, the fixing device is inverted U-shaped, and torsion spring adjustment devices are respectively embedded on the three inner sides of the inverted U-shaped fixing device and the upper end face of the base plate.

[0008] Preferably, the four rudder clamps are in a cross shape; and there is space between the four rudder clamps to accommodate the underwater vehicle.

[0009] A test method for a simulated load test system for an underwater vehicle includes the following steps.

[0010] S1: First, place the base plate on a horizontal surface; then install the underwater vehicle fixing device, pass the underwater vehicle through the fixing device, connect it to the fixing device, and then connect and fix the fixing device to the base plate.

[0011] S2: Then clamp the rudder clamp onto the rudder blade of the underwater vehicle. The rudder clamp is connected to the torsion bar spring. Install the torsion spring adjustment device into the fixing device and connect it to the torsion bar spring.

[0012] S3: Next, install the brake fixing device on the base plate and fix the magnetic powder brake on the brake fixing device. Use a coupling to connect one magnetic powder brake to the inner shaft of the underwater vehicle's propeller, and use a bevel gear to connect the other magnetic powder brake to the outer shaft of the underwater vehicle's propeller. After all devices are connected, turn on the brake control device.

[0013] S4: When an underwater vehicle moves, its rudder and counter-rotating propeller will be subject to water flow resistance. This simulated load test system uses magnetic powder brakes and torsion bar springs to mechanically load the inner and outer shafts and rudder of the underwater vehicle, thereby simulating the load of the underwater vehicle when it moves underwater.

[0014] After the system is powered on, the theoretical real load of the vehicle's propulsion system is calculated in real time through the thruster loading system. The brake parameters are adjusted by the control device to simulate this load. The deformation of the torsion bar spring is used to simulate the real load when ruddering underwater, thus realizing the real load simulation of the servo system.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention provides a simulated load testing system for underwater vehicles. When an underwater vehicle moves, its rudder and counter-rotating propeller are subject to water flow resistance. This simulated load testing system uses magnetic powder brakes and torsion bar springs to mechanically load the inner and outer shafts and rudder of the underwater vehicle, thereby simulating the load of the underwater vehicle during underwater movement. This load testing system is easy to install, has a reliable structure, and can ensure the stable operation of the simulated load testing process for underwater vehicles. Attached Figure Description

Each torsion spring adjustment device 11 has a torsion bar spring 10 facing inward; each torsion spring 10 has a rudder plate clamp 12 at its end. The four rudder plate clamps 12 are cross-shaped; space is left between the four rudder plate clamps 12 to accommodate the underwater vehicle.

[0031] The thruster loading system 1 includes a magnetic powder brake 5, a brake control device 6, a brake fixing device 7, a coupling 8, and a bevel gear 9. Two brake fixing devices 7 are mounted on the base plate 3. Magnetic powder brakes 5 are mounted on the two fixing devices 7 in a horizontal and vertical direction, respectively. The right end of the magnetic powder brake 5 in the horizontal direction is connected to the coupling 8, and the front end of the magnetic powder brake 5 in the vertical direction is connected to the bevel gear 9. The brake control device 6 is electrically connected to the two magnetic powder brakes 5.

[0032] The present invention also provides a test method for a simulated load test system for underwater vehicles, comprising the following steps:

[0033] S1: First, place the base plate 3 on a horizontal surface; then install the vehicle fixing device 4; next, pass the underwater vehicle through the vehicle fixing device 4 and connect it to the vehicle fixing device 4; then connect and fix the vehicle fixing device 4 to the base plate 3.

[0034] S2: Then clamp the rudder clamp 12 onto the rudder of the underwater vehicle. The rudder clamp 12 is connected to the torsion bar spring 10. Finally, install the torsion spring adjustment device 11 into the fixing device 13 and connect it to the torsion bar spring 10.

[0035] S3: Next, install the brake fixing device 7 on the base plate 3 and fix the magnetic powder brake 5 on the brake fixing device 7; then use a coupling to connect one magnetic powder brake 5 to the inner shaft of the underwater vehicle's propeller, and use a bevel gear 9 to connect the other magnetic powder brake 5 to the outer shaft of the underwater vehicle's propeller; after all devices are connected, turn on the brake control device 6.
