Description

Atmospheric pressure aerotrain

Technical field

The present invention（Utility model）It is related to a kind of suspension got up that suspends by train using the atmospheric pressure that air generates to arrange Vehicle and the roadnet of train operation

Background technology

Current bullet train is divided into two classes, i.e. wheel-rail train and magnetic suspension train.Present wheel-rail train is due to by itself The restriction of condition, speed cannot be too big, and otherwise surface resistance, air drag are too big, and the various noises of generation can be very big, due to rubbing The various abrasions wiped and generated can be very big, and operation cost can be very big.

Magnetic suspension train there are the shortcomings that mainly have the following：First, technology requirement is high, operation difficulty is big, the item needed Part is difficult to meet, and cost is extra-high；Second is that energy consumption is big, powerful magnetic force is generated by electric current, heavy car body is supported is Need very high current.And electric current is big, then the electric energy consumed is big；Third, in dense atmosphere, the speed of magnetic suspension train Cannot be too big, i.e., no more than 400km/h, otherwise transported department and passenger institute are difficult to because energy consumption and noise arrive greatly exceeded Receive.

Although many people propose to build the train of vacuum tunnel magnetic suspension speed per hour a thousand li in the near future recently, should Kind of train there are the shortcomings that also can be very much, mainly have：（1）A large amount of electric energy is consumed using magnetic suspension；（2）When passenger gets on or off the bus Because there are one, again to the transient process of normal pressure, to delay longer because the technical operation of the process is tight from normal pressure to vacuum Time, thus this train is not suitable for being chosen as short distance transport facility；（3）Passenger increases again in secure context by bus One is added because of the risk factor caused by compartment gas leakage；（4）As long as using magnetic suspension principle, just cannot absolutely eliminate strong Magnetic field issuable influence on human body；（5）The weight of object that train loads can never be very big, will not meet goods train It needs.

Invention content：

Train allows train to be reduced to minimum as possible to the pressure of track when running at high speed, so as to allow train by from track Frictional resistance be also reduced to minimum；Train side and upper surface is allowed to be reduced to minimum as possible by the resistance from air；It allows The loading capacity of train is significantly increased；The safety stability coefficient of bullet train is allowed significantly to be improved；It allows at a high speed The maintenance and repair expense of train can be reduced to minimum；The noise of train operation is allowed to be reduced to minimum.

Technical solution and feature

According to actual needs, atmospheric pressure aerotrain will be divided into two class, i.e.,：A train normally travels speed designs are small In the quasi- levitation high speed train of 400km/h；B train normally travels speed designs are that complete suspend more than 400km/h arranges at a high speed Vehicle.The aerotrain system of each class is segmented into three digest journals, i.e. suspension system, control system again（Including being oriented to and making It is dynamic）With dynamical system etc..

(1) chief component of suspension system and suspension theory are as follows：

（1）Component part：The suspension system of each aerotrain is all made of two big major parts：That is case（2）（It is static in-orbit Above road）With the inclined tab of train body side（10）

（2）Suspension theory：By taking normally travel speed designs are less than the quasi- levitation high speed trains of 600km/h as an example, i.e.,：Allow train rail Road (3) vacantly, allows car body lower section to have the space more than 100cm high.Again case is built above the track used in train（2）, cover Shell（2）There are two side and top surface, without bottom surface, case（2）Length length as entire track length (not set AT STATION Case）.

The headstock of train is done height a bit again, 10cm highly higher than compartment other parts or so.It will also be in train Load onto inclined tab in two sides（10）, inclined tab direction and current of traffic are into 15 ° -45° angle degree.In this way, when train is in case During high-speed motion, headstock can squeeze air into the space below headstock, inclined tab（10）It may be prevented from the sky below compartment Gas enters case（2）With car body（1）Between space, inclined tab（10）It can also be having leaked into case（2）With compartment（1）Between Partial air ejects.

In this way, case（2）With compartment（1）Between air will become very thin, compartment（1）Upper surface It is less than the atmospheric pressure that lower surface is subject to, train body by atmospheric pressure（1）Will by a resultant force of air pressure, Resultant direction be it is upward, when this resultant force F size be equal or close to train gravity G when, train will suspend or It is in close to suspended state.Train, which is in close to suspended state or the operation of complete suspended state, is all up state.

（Two）Main technical schemes in terms of other systems are：

（1）For the quasi- aerotrain of atmospheric pressure, the present invention is combined wheel-rail train and aerotrain, enables train Just suspending completely it is necessary to suspend completely, it is not necessary to suspend completely just by it is close suspend completely in a manner of run, train is complete It is complete to suspend or suspend close to complete（It is i.e. accurate to suspend）In the state of, all it is called normally travel.In this way, the dynamical system of train and leading It just can easily be solved to system.Dynamical system, guidance system are just using the related skill used in existing bullet train Art.

（2）Braking system will open up new pattern, by hydraulic technique, allow and move a part for car body and stationary orbit phase Contact increases the pressure between car body and track, so as to increase frictional resistance by hydraulic technique.

（3）For complete aerotrain, for suspending power still from atmospheric pressure, power uses existing magnetic suspension The dynamical system of train, is oriented to and braking is also all using the prior art of magnetic suspension train

（4）Become rail problem

The either accurate still complete aerotrain that suspends, a set of wheel is respectively arranged respectively at compartment top and bottom, in road center row Using wheel above compartment when sailing（5）Traveling, AT STATION using the wheel of car bottom during change rail（9）Carry out change rail.

（5）In order to reduce resistance of the air to headstock to the greatest extent, train head will be manufactured into a wedge shape, the length of wedge Should be 100 with the ratio between thickness：1.5

Advantageous effect of the present invention

With the high-speed maglev train in Shanghai（V=500km/h or so）The two is compared, two row trains according to equal-wattage when driving, The speed of the complete aerotrain of atmospheric pressure can reach higher than 1000km/h, i.e. speed can be faster；Roadnet cost can be more simultaneously It is low；Safety coefficient is very big.

For the quasi- aerotrain of atmospheric pressure, compared with the Beijing-Shanghai express railway runed now, two row trains are according to identical When driving, the speed of the quasi- aerotrain of atmospheric pressure can reach higher than 800km/h power, i.e. speed can be faster；Safety coefficient is very big, Because wear it is minimum due to youngster's operation cost it is extremely low.

It can and greatly cut operating costs in this way, allow ordinary people that can also there is economic capability to take atmospheric pressure suspension row Vehicle.
