Description

Technical Field

[0001] The present invention belongs to the field of cross - medium experiments, and particularly relates to a vehicle motion acceleration device and method. Background Art

[0002] In the vehicle water - exit experiment, it is impossible to restore the water - exit of each vehicle in a 1:1 ratio. Therefore, it is necessary to scale down the model. In the scaled - down water - exit experiment, not only the model needs to be scaled down, but also the water - exit speed and water - exit pressure need to be synchronously reduced according to the scale factor to ensure that the scaled - down water - exit model after scaling is consistent with the prototype water - exit model.

[0003] In the reduced - pressure water - exit scaled - down experiment, the circumferential direction of the vehicle is usually sealed with a sealing ring, and then high - pressure gas is used to push to achieve the purpose of high - speed water - exit of the vehicle. Therefore, during the experiment in a negative - pressure environment, there is an atmospheric pressure mass at the bottom of the vehicle. As the external environment pressure of the motion acceleration cylinder decreases, there is a risk of being pumped out. Moreover, the traditional motion acceleration cylinder cannot adjust the pressure on the shoulder of the vehicle between the sealing rings, which has a great adverse impact on the development of the shoulder exhaust pressure experiment for water - exit in a negative - pressure environment. Summary of the Invention

[0004] In view of this, the present invention aims to provide a vehicle motion acceleration device and method to solve the problem that in the negative - pressure scaling experiment, the vehicle has a risk of being pumped out from the motion acceleration cylinder by atmospheric pressure as the environmental pressure decreases.

Therefore, the two intake ends are sufficient to conduct experiments according to different experimental requirements.

The same principle applies to the connection of the other part of the air outlet ends to the bottom intake end of the air chamber 8.

[0064] The pressure regulating assembly is provided with multiple pressure regulating outlet ends and is connected to the pressure stabilizing holes one by one to regulate the shoulder pressure during the ejection process of the vehicle in the acceleration cylinder assembly.

An irregular hole is provided on the side wall of the middle acceleration cylinder section 3 for use with the platform support. The angle between the position of the irregular hole and the boss is 90°, which is convenient for vertical insertion to complete the connection. At the same time, in order to improve the connection strength, the cylinder opening 1, the upper acceleration cylinder section 2, the middle acceleration cylinder section 3, and the lower acceleration cylinder section 4 are all provided with corresponding threads at the end that cooperates with the acceleration cylinder connector 5, and are connected in a threaded connection form to improve the sealing performance and connection strength.

It is only necessary to replace the model of the adapter seat 6 according to the models of different pipelines. The adapter seat 6 adopts the prior art, and any adapter seat 6 that can adapt to the connection of holes and different pipelines can be used in this application.

[0067] In this embodiment, the air chamber 8 is provided with a plurality of screw holes for installing a pressure sensor 20, and the screw holes without the pressure sensor 20 installed are blocked by plugs. Multiple positions of the pressure sensor 20 need to be set so as to truly obtain the data during the acceleration process of the vehicle and the pressure data of the water backflow after the vehicle is launched, which is convenient for subsequent analysis. The plugs are specifically provided in two types, a first plug 9 and a second plug 10, and their diameters are different, and are used to block the screw holes for installing different types of sensors. After blocking, redundant measurement points can be reduced, and redundant data interference can be reduced.

[0070] In this embodiment, the power air source 14 is externally coated with a heat preservation layer 18 and is provided with a heat source 17 for heating the air source in the power air source 14. Through the setting of the heat source 17, the gas can be heated, and the gas with heating ability can be used to propel the vehicle, which can simulate the hot jet flow of the actual vehicle movement.

[0071] In this embodiment, a pressure and temperature sensor 19 is provided on the power air source 14. It is used to monitor the temperature of the heated gas.

[0072] In this embodiment, the acceleration cylinder assembly, the air chamber 8 and the initial volume chamber adjustment cylinder 12 are all made of transparent materials. Specifically, acrylic materials are selected, which can have good strength and at the same time cooperate with a high-speed camera to well record and observe the acceleration process and the water backflow process.

[0075] S2. By controlling the solenoid valve group 15 and the flow dividing valve 16, the high-pressure gas in the power gas source 14 enters the air chamber 8 according to the specified time sequence. After being stabilized by the initial volume chamber adjusting cylinder 12, it pushes the vehicle. The pressure regulating component outputs pressure on the path where the vehicle is pushed out in the acceleration cylinder component. The pressure sensor 20 transmits all the data during the whole process of the vehicle being completely pushed out of the acceleration cylinder component and when the water outside the cylinder backfills into the bottom of the acceleration cylinder component after the vehicle completely exits the acceleration cylinder component to the controller for recording.

[0076] For the installation method of this device, first, select suitable acceleration cylinder connectors 5, adapter seats 6, plugs 1, plugs 2, vent hole adapter seats 11, sealing rings 7, initial volume chamber adjusting cylinders 12 and solenoid valve groups 15 according to the test requirements, and install them in sequence from bottom to top.

The power air pipe of the air chamber 8 is connected to the solenoid valve group 15 through the flow dividing valve 16. The solenoid valve group 15 is connected to the power gas source 14 through an air pipe. The special-shaped hole in the middle section 3 of the acceleration cylinder is installed corresponding to the external platform, and the acceleration cylinder component is fixed. Then, lower the external platform to the predetermined test position to conduct the negative pressure environment water outlet test.

[0078] The present invention adopts a modular design. By adjusting the cylinder section and the cylinder mouth structure, it can be flexibly deployed to adapt to the simulation motion requirements of multi-scale vehicles and the requirements of scale-down tests; by adjusting the sealing structure, it can avoid the risk that the vehicle is pumped out of the motion acceleration cylinder by the atmospheric pressure as the environmental pressure decreases; by adjusting the air chamber and the initial volume chamber structure, it solves the problem that the volume of the initial volume chamber is fixed and the ventilation position is single; by opening holes on the cylinder wall and setting adapter seats, it solves the problem that during the negative compression ratio test and the shoulder exhaust test of the scale-down vehicle during decompression water outlet, the shoulder pressure cannot be isolated from the high pressure at the bottom of the cylinder, and increases the data measurement points; by changing the material of the motion acceleration cylinder, it solves the problem that the state of water backfilling in the acceleration cylinder after the vehicle exits the cylinder cannot be observed.
