Description
Technical field
The invention belongs to magnetic levitation technology fields, and in particular to a kind of track compensation dress of passive type magnetic suspension train
It sets more particularly to a kind of core rail technology for passive type magnetic suspension train.
Background technique
The high-speed rail epoch afterwards, on the one hand, be increasingly difficult to using the track train speed-raising of wheel-rail technology；On the other hand, with fortune
The raising of scanning frequency degree, train are run at high speed under the conditions of normal barometric pressure, and suffered air drag is increasing, and train is in energy consumption
Also more and more uneconomical.In this case, using vacuum pipe technology, vehicle is allowed to operate in the pipeline of class vacuum environment,
Speed, reduction multiple purposes such as resistance and energy conservation and environmental protection are improved to reach, has become the new scientific research of technical field of rail traffic
Forward position.The research boom for having started vacuum pipe train both at home and abroad, among these, using passive type magnetic suspension train in vacuum
The scheme run in pipeline, has there is extensive research.
Passive type magnetic suspension train, is driven by linear motor, is advanced in the initial stage of operation using wheel track
Mode.Meanwhile the suspending module on train and suspension railway interact and form vortex induction, to generate one to train
Upward suspending power.After train reaches certain speed, suspending power promotes train to de-orbit and enters suspension-cruising condition.
Due to without mechanical resistance, and without air drag, only exists intrinsic reluctance force and (tend to be permanent after reaching certain speed
It is fixed), therefore, ultrahigh speed operation theoretically may be implemented in passive type magnetic suspension train, and required energy consumption is lower, more economical
Operation.
Passive type magnetic suspension train is driven by linear motor, when low speed, is run, is reached in orbit by wheel
To after certain speed, suspending module suspends train with suspending power caused by suspension railway interaction.Among these, suspension rail
The effect in road has two aspects, directly carries train when first is that being carried on low speed, travels in track for wheel；Second is that reaching one
After constant speed degree, train is carried by suspending power, is run in track for suspending module.
Suspension railway is generally made of aluminium alloy extrusions, and extensive, mass production is easy to.It under normal conditions, can be with
As traditional rail, 12.5m, 25m even track of 500m long size is made.
But in actual use, under the conditions of being in continually changing temperature due to vacuum pipe, its own can be with temperature
The variation of degree and expand with heat and contract with cold, the length of tube body can constantly change, and pipe end can generate displacement.And the track inside pipeline by
It in vacuum environment, is not influenced by ambient temperature, therefore its length will not change with the variation of pipeline.With pipeline
The displacement that end generates, suspension railway are possible to misplace with pipeline, lead to suspension railway or longer than pipeline, or compare pipeline
It is short.The dislocation of suspension railway and pipeline will directly affect the operational safety of train, to generate security risk.Due to pipeline with
Dislocation is generated between track, causes to interrupt among track, so hidden danger is generated to traffic safety.
Summary of the invention
It is an object of the present invention in view of the foregoing drawbacks, provide a kind of track compensation dress of passive type magnetic suspension train
