Abstract
The present invention provides a kind of simulators of aircushion vehicle ship wave, are made of pond, nano magnetic liquid and electromagnet, belong to simulator field.The water of certain depth is housed, nano magnetic liquid not soluble in water, density ratio water is small is floated on the water surface of pond, and polylith electromagnet is disposed on the horizontal plane immediately below basin bottom, and magnetic field can be generated in surface when each electromagnet is powered in pond.During work, energization, the down sequences of each electromagnet are controlled by specified rule, the shifting magnetic field with spatial position change can be generated on the water surface, successively attract magnetic field institute through part nano magnetic liquid extruding the water surface, simulate navigation of the aircushion vehicle on the water surface, and then evoke the fluctuation of the water surface around, obtain the ship wave of aircushion vehicle.The present apparatus has the advantages that simple in structure, control is accurate, the problem of can accurately simulating the speed of a ship or plane, course and the air cushion pressure of aircushion vehicle, the speed of a ship or plane, course are difficult to control when being not in and being tested using true air cushion vehicle model.
Description
Technical field
The present invention provides a kind of aircushion vehicle ship wave simulator, the magnetic field suction nano magnetic liquid generated by electromagnet
The mode for squeezing the water surface simulates navigation of the aircushion vehicle in the water surface, produces aircushion vehicle ship wave, belongs to simulator field.
Background technology
The radiation wave that aircushion vehicle is formed when being navigated by water on the water surface is referred to as aircushion vehicle ship wave.The principle of aircushion vehicle ice-breaking
It is to wash away floating ice using aircushion vehicle ship wave, the ice of bulk is made to be broken into trash ice, navigation channel is opened up in the navigation for ordinary ships.Cause
This, research aircushion vehicle ice-breaking technology unavoidably needs to carry out experimental study to the ship wave of aircushion vehicle.
The main method for carrying out experimental study to aircushion vehicle ship wave at present is in pond using jet air-cushion ship ship model
In pulled or from navigate, produce ship wave.For towing trial, aircushion vehicle can only generally be allowed to navigate along straight line with certain speed
Row, i.e. course are single, the speed of a ship or plane is limited；For self-propulsion test, the speed of a ship or plane course of aircushion vehicle is general to be also difficult to precisely although adjustable
Because the frictional force between aircushion vehicle and the water surface is extremely low, phenomena such as hull breaks away, fore is turned easily occurs for control.In addition, gas
Pad ship ship model inevitably causes spray splash in jet, these sprays not only interrupt the view, and dropping back into after the water surface will also draw
Water surface perturbation is played, interference is brought to the measurement of ship wave.Therefore, the existing side using the direct shipbuilding traveling wave of aircushion vehicle ship model
The problem of there is method the speed of a ship or plane, course to be limited, and test accuracy is not high.
Invention content
The present invention provides a kind of aircushion vehicle ship wave simulators, it is therefore intended that improves aircushion vehicle ship wave simulator
Overall performance, make it have the wider array of speed of a ship or plane, course simulation context and test accuracy, and the spray of splashing will not be generated.
The object of the present invention is achieved like this：A kind of aircushion vehicle ship wave simulator, comprising pond, nano magnetic liquid and
Electromagnet is equipped with the water of certain depth in pond, and nano magnetic liquid is floated on the water surface of pond, and basin bottom arranged just beneath has electricity
Magnet.Specific structural features are as follows：
1. density is selected to be less than water and the nano magnetic liquid not dissolved in, it is made to float on the water surface, and cover all the water surface；
2. basin bottom has been evenly arranged polylith electromagnet, all electromagnet are located in same level, every block of electromagnet
It can independently be powered, power off, the magnetic field of some strength is generated on horizontal plane that can be where the nano magnetic liquid in surface after energization, is broken
Magnetic field disappears after electricity.
Compared with prior art, advantage of the invention is that：(1) air cushion jet is simulated by electromagnetic attracting force nano magnetic liquid
It is formed and acts on the pressure that hovers on the water surface, the integrality of the water surface can be kept, avoided generating traditional aircushion vehicle The water splash in all directions
Ill effect is conducive to the accurate measurement of ship wave；(2) quietness is good, will not generate such as the noise of traditional aircushion vehicle air blower,
Be conducive to build more comfortable experimental situation；(3) response speed of electromagnetism is exceedingly fast, and is arranged in by control more immediately below pond
Block electromagnet, can simulate the aircushion vehicle ship wave navigated by water along free routing with arbitrary speed, and traditional air cushion vehicle model
Due to being limited by trailer speed or driving device power, the attainable velocity interval of institute is limited, and course is also limited or more difficult
It is precisely controlled；(4) electromagnet apparatus is not in direct contact with water, is not sealed and etching problem, makes the maintenance work of device very
Simply.
Description of the drawings
Fig. 1 is oblique two surveys view of structure of the present invention；
Fig. 2 is the bottom view of structure of the present invention.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1~Fig. 2 is the example of structure of the present invention, meets the water of test requirements document in pond 1 equipped with depth, and density is less than water
And nano magnetic liquid 2 (such as carrier fluid is the nano magnetic liquid of fat) not soluble in water is covered on the water surface in pond 1；Polylith rectangle electromagnet
On the 3 close horizontal planes being arranged in immediately below pond 1, one electromagnet array with length and width identical with pond of composition, often
Block rectangle electromagnet 3 can independently be powered, power off, and can generate magnetic on the nano magnetic liquid 2 right over the electromagnet 3 during energization
, magnetic field disappears after power-off.
The mode of aircushion vehicle shipping agency wave simulation is：According to aircushion vehicle navigation route planned in advance and the speed of a ship or plane, electricity is determined
Energization, down sequences and the conduction time of magnet 3, it is desirable that when aircushion vehicle passes through the surface of any block electromagnet, the electromagnet
It is powered, and when aircushion vehicle leaves the surface of the electromagnet, electromagnet power-off.According to this rule, electromagnet 3 is controlled
It is powered, power-off, generates magnetic field right over electromagnet 3 during due to being powered, there is paramagnetic nano magnetic liquid 2 to be squeezed downwards by attracting
The water surface is pressed, generates on the water surface and hovers the identical function and effect of pressure with aircushion vehicle；When magnetic field on the water surface when moving, nano magnetic
The power that is pressed down against of liquid 2 is shifted along, and simulates the effect that aircushion vehicle navigates by water above the water surface, and then gas is generated on the water surface
