Vacuum line magnetic suspension train is a kind of vehicles with " vacuum steel pipe transmission " for theoretical core, has superelevation
Speed, high safety, low energy consumption, noise is small, pollutes the features such as small.The running environment of vacuum line magnetic suspension train compared to high-speed rail and
Magnetic suspension train is harsher, and travel speed is also higher, reaches high subsonic speed, proposes higher technology to train body structure and wants
It asks.
Traditional high-speed rail and magnetic suspension train are using single stressed-skin construction.In vacuum pipe, single covering will bear vehicle simultaneously
Body structural loads and car body inside and outside differential pressure load, in order to cope with the use environment of this harshness, covering must design very strong, increase
Construction weight is added.Simultaneously as car body shape limits, covering cannot be made into regular circle, to leakproofness and very big
Test has some potential safety problems.Using double stressed-skin constructions, inside and outside covering can be allowed to be solely subjected to differential pressure loading and knot respectively
Structure load, inside panel can not be limited by car body shape, can be designed to the circular cross-section conducive to pressure-bearing, and exterior skin is solely subjected to
Structural loads, the influence without worrying pressurization load.This double stressed-skin constructions are more suitably applied to vacuum than single stressed-skin construction
Pipeline magnetic suspension train.

Beneficial effect
The beneficial effects of the present invention are: the double covering pressurized constructions of vacuum line magnetic suspension train of the present invention, it can be light
Realize vacuum line magnetic suspension train function of increasing pressure, effectively reduce the deformation of car body sharp corner, avoid due to car body deform with
Duct wall contact, while also improving the air-tightness of car body.
Using double stressed-skin constructions, inside panel can be designed to the circle conducive to pressure-bearing due to not limited by car body shape
Section, the expansion, uniform expansion outward under pressurization load effect.A part pressurization load is absorbed by inside panel itself compatible deformation
Fall, another part passes to exterior skin by support construction.Exterior skin bears complete vehicle structure load, aerodynamic loading and passes through branch
The partial boost load that support structure transmitting comes.Load is pressurized by inside panel, support construction and exterior skin shared, it can be with
Car body deflection is effectively reduced, car body air-tightness is improved.This double stressed-skin constructions are more suitably applied to vacuum than single stressed-skin construction
Pipeline magnetic suspension train.
