Description
Technical Field
The invention relates to the technical field of suspension trains, in particular to a high-speed dynamic pressure air-float rail vehicle and a rail structure thereof.
Background
The traditional high-speed rail obviously increases along with the increase of the vehicle speed by means of friction between wheels and rails, and when the vehicle reaches a super-high-speed running state, a large amount of energy is consumed by driving a train, and even the further increase of the running speed of the train is hindered. In order to further increase the running speed of the vehicle, the wheels of the train in a normal running state need to be separated from the track.
In this context, magnetic levitation trains have been developed, in which the body levitation is achieved by means of magnetic forces generated by high currents in high-temperature superconductors. But at present, the critical temperature of the high-temperature superconducting material is still lower, and the refrigeration cost is high, so the economic efficiency of the technical route is poorer. Another technical route for achieving train levitation is air levitation, i.e., a layer of high pressure air cushion is established between the train and the track to separate the train body from direct contact with the track.
The working principle of the hovercraft and the air-float vehicle is that the bottom of the hovercraft or the air-float vehicle body is separated from the ground or the water surface through a high-pressure air cushion, but a mechanical air injection device is also needed to be arranged on the structure, the structure is complex, the energy consumption is high, and the application scene is limited. At present, the ground effect aircraft in the aircraft field can be considered to apply the air suspension technical principle. Due to the wing-to-ground effect, the airflow creates a high pressure air cushion between the wing and the ground/water surface, creating more lift. However, the structural features of the current ground effect aircraft are still closer to the aircraft, the wing body of the current ground effect aircraft has a wing with huge size, the wing body cannot be fused, and the current ground effect aircraft cannot be directly applied to trains running at high speed near the ground.
Therefore, the inventor provides a high-speed dynamic pressure air-float rail vehicle and a rail structure thereof by virtue of experience and practice of related industries for many years, so as to overcome the defects of the prior art.

The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 to 4, the invention provides a high-speed dynamic pressure air-float rail vehicle 100, which comprises a vehicle body 1, wherein the vehicle body 1 comprises a bottom plate 11, a top plate 12, a head plate 13 and two vehicle body side plates 14, a seat is arranged in the vehicle body 1, a window 19 is arranged on each vehicle body side plate 14, and two rows of wheels 2 are arranged below the bottom plate 11; the length of each side plate 14 is the same as that of the top plate 12, and the lower edge of each side plate 14 is lower than that of the bottom plate 11, so that resistance is increased, gas is effectively prevented from escaping from the side surface, and pressure difference between the bottom of the vehicle and the roof is facilitated; the nose plate 13 is arranged in a curved surface and inclines towards the tail of the vehicle from top to bottom, the tail end of the vehicle body 1 is provided with a flow limiting plate 15 with the bottom end capable of throttling and swinging, the lower edge of the flow limiting plate 15 is lower than that of the bottom plate 11, the flow limiting plate 15, the bottom plate 11 and the two vehicle body side plates 14 form a vehicle bottom high pressure area, the vehicle bottom high pressure area can form a pressure difference with the upper part of the top plate 12, and the high-speed dynamic pressure air-float rail vehicle floats when the pressure difference is larger than or equal to the gravity of the high-speed dynamic pressure air-float rail vehicle.
The contact force between the wheels and the track can be adjusted by adjusting the opening degree of the restrictor plate 15 and adjusting the protrusion amount of the lower edge of the restrictor plate 15 lower than the bottom plate 11, and when the speed needs to be reduced, the opening degree of the restrictor plate 15 is increased, the protrusion amount is reduced, and the contact force between the wheels 2 and the track is increased.
The appearance of the head of the vehicle body 1 refers to the appearance of a bow, the upper surface (the top plate 12) of the vehicle body is similar to a plane, and the lower surface (the bottom plate 11) of the vehicle body is smoothly connected with the head plate 13 (the head plate 13 and the bottom plate 11 can be integrally formed) and extends backwards parallel to the top plate until reaching the tail of the vehicle. The space below the vehicle body (below the bottom plate 11) is gradually reduced from the head along the curved lower surface of the head, and reaches a fixed value at the joint of the bottom of the head plate 13 and the bottom plate 11 until the space suddenly changes to a minimum value along the part from the lower surface of the vehicle body (the bottom plate 11) to the tail.
The reason why the high-speed dynamic pressure air-float rail vehicle can float is analyzed as follows: as shown in fig. 1, air above the roof (above the roof panel 12) flows along the upper surface (the roof panel 12) of the high-speed dynamic pressure air-floating rail vehicle 100 at a vehicle speed, and the roof is approximately at atmospheric pressure because the air pressure is less affected by the traveling of the high-speed dynamic pressure air-floating rail vehicle 100. The air below the roof forms a standing pressure on the locomotive under the obstruction action of the lower surface (bottom plate 11) of the locomotive. Then, air is introduced into the vehicle bottom along the lower surface of the vehicle head (the bottom plate 11) through the air inlet channel, under the throttling action of the throttling plate 15, throttling high pressure is formed at the throttling plate 15 at the tail of the vehicle, and because the pressure loss is small in the process from the joint of the vehicle head plate 13 and the bottom plate 11 to the tail of the vehicle (the tail end of the vehicle body 1), the pressure at the bottom of the vehicle body is approximate to the pressure at the throttling plate 15 at the tail of the vehicle. The parking pressure of the headstock and the throttling high pressure of the tailstock form a high pressure area at the bottom of the vehicle. The pressure above the roof is atmospheric pressure, the pressure below the bottom is a high-pressure area, pressure difference between the upper surface and the lower surface of the high-speed dynamic pressure air-float rail vehicle is formed, and the high-speed dynamic pressure air-float rail vehicle floats.
According to the high-speed dynamic pressure air-floating rail vehicle, an air-floating principle and a rail train technology are fully fused, the air pressure is built by means of air dynamic pressure naturally generated when the vehicle runs at high speed, the vehicle does not need to actively inject high-pressure air between the vehicle and a rail, and obvious lifting force is generated on the rail vehicle by means of the ground effect, so that a vehicle body and wheels of the vehicle are separated from direct contact with the rail, and the running speed is effectively improved; the contact force between the wheels and the track is stably adjusted by adjusting the opening of the flow limiting plate, so that the speed of the vehicle is adjusted; the invention not only keeps the original characteristics of high speed, large bearing capacity, low manufacturing cost and the like, but also effectively improves the stability and operability of the air-floating rail vehicle. The high-speed dynamic pressure air-float rail vehicle disclosed by the invention generates a high-pressure air cushion in a high-speed running state to achieve the effect of flying, and can solve the problem of low stability of the aircraft.
Further, as shown in fig. 1, 2 and 3, a propeller 16 extending upward is disposed on the top plate 12, and the propeller 16 is used for providing traction force, adjusting the magnitude of the traction force, and changing the running speed of the high-speed dynamic pressure air-float rail vehicle 100. In the present embodiment, the number of the propellers 16 is plural, and the propellers are provided at intervals in the longitudinal direction of the top plate 12.
Further, as shown in fig. 1 and 3, a balance weight 17 is disposed on the top plate 12, and the balance weight 17 is used for balancing a couple of the high-speed dynamic pressure air-float rail vehicle 100 in an unbalanced state. During acceleration, floating, falling and the like of the high-speed dynamic pressure air-floating rail vehicle 100, the high-speed dynamic pressure air-floating rail vehicle 100 is unbalanced in stress and generates a couple, which easily causes the vehicle to turn on its side, and the balance weight is used for balancing the couple of the high-speed dynamic pressure air-floating rail vehicle 100 in an unbalanced state, so that the high-speed dynamic pressure air-floating rail vehicle 100 is in a stable state.
Further, as shown in fig. 1, the radius of curvature of the head plate 13 decreases from top to bottom, and the head plate 13 protrudes toward the forward direction of the high-speed dynamic pressure air-bearing rail vehicle.
Further, as shown in fig. 1, a connecting shaft 18 is provided at the rear end of the vehicle body 1, and the top of the restrictor plate 15 is hinged to the connecting shaft 18.
In the present embodiment, the connecting shaft 18 is located at the top or middle of the rear end of the vehicle body, and the specific position is determined according to the actual driving process.
As shown in fig. 1 and fig. 2, the present invention further provides a track structure 3 for a high-speed dynamic pressure air-float rail vehicle, which includes two rows of tracks 31 arranged in parallel and track side plates 32 located at two sides, wherein the distance between the two track side plates 32 is greater than the distance between the two vehicle body side plates 14, the track side plates 32 extend upward from the bottom of the track structure, and the track side plates 32 are used for isolating the ambient air flow interference.
The track structure 3 is in a concave arrangement, the high-speed dynamic pressure air-floating track vehicle 100 runs along the fixed track 31, the track side plates 32 on the two sides are isolated from the interference of the ambient air flow, and the high-speed dynamic pressure air-floating track vehicle 100 is prevented from violently shaking. The pressure of the high-pressure area at the bottom of the car is generated mainly by the motion of the car head, and the dynamic pressure of the car head is generated according to the fluid dynamics theory
The pressure drop is small in the process of transferring the air pressure from the vehicle head to the vehicle tail (because the space of the vehicle bottom is compared)Large). The rail side plates 32 reduce the escape of gas from the sides and help maintain vehicle bottom pressure.
Further, the vehicle body side plate 14 and the track side plate 32 are arranged at a first interval, and a narrow air passage is formed between the vehicle body side plate 14 and the track side plate 32 to prevent the leakage of gas escaping from a high-pressure area at the bottom of the vehicle through the side surface.
The distance between the vehicle body side plate 14 and the track side plate 32 is narrow, and a fine air channel is formed, so that the leakage of air escaping from the vehicle bottom through the side wall can be prevented, and the high pressure is formed at the vehicle bottom.
After the high-speed dynamic pressure air-float rail vehicle 100 is started, the high-speed dynamic pressure air-float rail vehicle 100 continuously accelerates on the fixed rail 31. As shown in fig. 4, during acceleration, the air is divided into two parts at the vehicle head: a part of the gas flows rapidly along the upper surface (roof panel 12) of the vehicle body; the other part flows slowly along the lower surface (bottom plate 11) of the vehicle body, and pressure difference is formed between the upper part and the lower part of the vehicle body 1 by utilizing the throttling function of the flow limiting plates of the parking spaces. When the pressure difference is greater than or equal to the gravity of the high-speed dynamic pressure air-float rail vehicle 100, the high-speed dynamic pressure air-float rail vehicle 100 floats at a high speed.
By controlling the position of the center of gravity, the pressure difference and the power of the high-speed dynamic pressure air-float rail vehicle 100, the high-speed dynamic pressure air-float rail vehicle 100 flies at a certain fixed speed at a certain fixed position above the track (steel rail).
When the high-speed dynamic pressure air-float rail vehicle 100 arrives at a station, the opening degree of the flow limiting plate is increased, the extending amount of the flow limiting plate is reduced, the high-speed dynamic pressure air-float rail vehicle 100 falls on a rail, the contact force between the wheels 2 and the rail is increased, the traction force is gradually reduced, and finally the high-speed dynamic pressure air-float rail vehicle 100 slides into the station.
The high-speed dynamic pressure air-bearing rail vehicle 100 relies on air buoyancy to reduce the contact force between the wheels and the rail, and even to float on the rail. When the vehicle needs to turn, the vehicle speed is reduced, and the vehicle body is prevented from being thrown out of the track under the action of centrifugal force; when the vehicle speed is reduced, the contact force between the wheels and the track is increased, and the centripetal force required by the vehicle to turn can be provided. There are two modes of turning, the first being: the opening degree of the restrictor plate 15 is unchanged, the running speed of the high-speed dynamic pressure air-float rail vehicle 100 is reduced, the contact force between the wheels and the rail is increased, and the vehicle turns; the second method is as follows: before entering a turning road section, the running speed of the high-speed dynamic pressure air-float rail vehicle 100 is unchanged, the opening degree of the restrictor plate 15 is increased, the extension amount of the restrictor plate 15 is reduced, the pressure difference between the bottom of the vehicle and the roof of the vehicle is reduced, the high-speed dynamic pressure air-float rail vehicle 100 falls on a rail, the contact force between the wheels 2 and the rail is increased, and stable turning is realized on the rail. In the second mode, measures such as braking are not needed, energy is saved, and the service lives of components such as rails and wheels are prolonged.
From the above, the high-speed dynamic pressure air-float rail vehicle of the invention has the following beneficial effects:
according to the high-speed dynamic pressure air-floating rail vehicle, an air-floating principle and a rail train technology are fully fused, the air pressure is built by means of air dynamic pressure naturally generated when the vehicle runs at high speed, the vehicle does not need to actively inject high-pressure air between the vehicle and a rail, and by means of the ground effect, remarkable lifting force is generated on the rail vehicle, so that a vehicle body and wheels of the vehicle are separated from direct contact with the rail, and the running speed is effectively improved; the contact force between the wheels and the track is stably adjusted by adjusting the opening of the flow limiting plate, so that the speed of the vehicle is adjusted; the invention can increase the opening of the flow-limiting plate and reduce the pressure difference between the bottom of the car and the top of the car under the condition of constant running speed, so that the contact force between the wheels and the track is increased, the stable turning is realized on the track, measures such as braking and the like are not needed, the energy is saved, and the service life of the components such as the track, the wheels and the like is prolonged.
The invention not only keeps the original characteristics of high speed, large bearing capacity, low manufacturing cost and the like, but also effectively improves the stability and operability of the air-floatation rail vehicle; the high-speed dynamic pressure air-float rail vehicle disclosed by the invention generates a high-pressure air cushion in a high-speed running state to achieve the effect of flying, and can solve the problem of low stability of the aircraft.
