Abstract
The invention relates to a transparent drag reduction roadbed technique of magnetic levitation vehicle, wherein it is formed by transparent hole and acute-angle drag reducer, wherein said transparent hole connects the longitudinal beam and the transverse connecting beam, to form the transparent hole roadbed arranged in equal distance; the main beam and the connecting beam can be made from steel bar concrete, steel or other composite; said acute-angle drag reducer arranges one acute element at the face of connecting beam; two right angle surfaces of acute element are connected to the main beam and connecting beam, while they are equal to the connecting beam, flat and smooth; said acute drag reducer can be processed independently, or integrated with the connecting beam, while its material is same as the connecting beam; when the airflow generated by vehicle impacts the acute angle, lots of disturb airflow is separated under the connecting beam to reduce the disturbance on the vehicle.
Description
Technical field
The invention belongs to the traffic route technical field, relate in particular to a kind of transparent drag reduction road bed technique for magnetic suspension train.
Background technology
The high-speed rail transportation great majority all adopt the overhead technology on ground of road, are beneficial to people, animal, other vehicles and walk under the viaduct, guarantee its safety.Overhead technology is all adopted in the magnetic suspension of Germany TR series, the magnetic suspension of Japanese MLX series.The shortcoming that this technology is brought is the sunlight that blocks under the viaduct, is unfavorable for plant growing.See " magnetic levitation railway system and technology " (China Science Tech Publishing House 2003.11).
Summary of the invention
The object of the present invention is to provide a kind of transparent drag reduction road bed technique for magnetic suspension train,, alleviate the weight of viaduct, reduce cost to strengthen the environment protecting of viaduct.
For achieving the above object, transparent drag reduction road bed technique for magnetic suspension train provided by the invention is made of loophole and acute angle damping device two parts, wherein:
The loophole part is connected and fixed vertical girder and transverse strut, forms the loophole roadbed of equidistantly arranging;
The acute angle damping device is met an acute angle body on the car face for being arranged on the contact beam, and two right angle faces of this acute angle body connect girder and contact beam respectively, and to cross facing contour and smooth smooth with getting in touch beam;
By the setting of above-mentioned acute angle damping device, when air-flow that train drives and the collision of this acute angle, most of disorderly air-flow is isolated in the below of contact beam, has reduced the interference drag to train thus.
Described transparent drag reduction road bed technique for magnetic suspension train, wherein, girder is steel concrete or steel with the material of manufacturing of getting in touch beam.
Described transparent drag reduction road bed technique for magnetic suspension train, wherein, the acute angle damping device is for being fixed on the contact beam after the processing separately.
Described transparent drag reduction road bed technique for magnetic suspension train, wherein, acute angle damping device and contact beam are integrally manufactured.
Described transparent drag reduction road bed technique for magnetic suspension train, wherein, the material of acute angle damping device is steel concrete or steel.
The present invention has solved the printing opacity problem by perforate on roadbed, has reduced the interference drag of the air turbulence of contact beam formation to magnetic suspension train by the acute angle damping device is set again.
Description of drawings

Fig. 2 is along the generalized section of A-A line among Fig. 1.
The specific embodiment
The following stated content is the detailed description of in conjunction with the accompanying drawings the present invention being done, and should not be understood that it is limitation of the invention.
Transparent drag reduction road bed technique for magnetic suspension train of the present invention is made of loophole and acute angle damping device two parts.Wherein: the loophole part, vertical girder and transverse strut are connected and fixed, form the loophole roadbed of equidistantly arranging.Girder can be steel concrete, steel or other composite materials etc. with the material of manufacturing of getting in touch beam.
Acute angle damping device part is met the car face at the contact beam, and an acute angle body is set, and two right angle faces of this acute angle body connect girder and contact beam respectively, and with to get in touch the beam face contour and smooth smooth, also can think this extension above contact beam.The acute angle damping device can be processed separately, also can be integrally manufactured with the contact beam, and its material is with to get in touch beam identical.The air-flow that drives when train is during with the collision of this acute angle, and most of disorderly air-flow is isolated in the below of getting in touch beam, has reduced the interference drag to train thus.
, be printing opacity drag reduction viaduct bed structure schematic top plan view please referring to accompanying drawing 1.As can be seen from the figure, girder 1 is born the longitudinal loading of overhead roadbed, is main bearing member, and its height can design according to load and rigidity requirement, can be greater than the height of contact beam 2.Contact beam 2 two ends are fastened on the girder 1, and the acute angle damping device is an acute angle body 3, is fixed on girder 1 and gets in touch on the beam 2.The three can be made into integration, and its material can be steel concrete, steel or other composite materials or the like.Sunlight is from loophole 4 directive ground.
Please referring to Fig. 2, be among Fig. 1 along the generalized section of A-A line.As can be seen from the figure, the acute angle body 3 of triangle is arranged on the car face of the meeting direction of contact beam 2, two right angle faces of this acute angle body 3 connect girder 1 and contact beam 2 respectively, and contour and smooth smooth with the car face excessively of getting in touch beam 2, also can think this extension above contact beam 2.Acute angle body 3 can be processed separately, also can be integrally manufactured with the contact beam, and its material can be with to get in touch beam identical.To reduce the running resistance of train.Acute angle body 3 as the acute angle damping device equidistantly is arranged between the longitudinal beam 1 with getting in touch beam 2, forms whole roadbed.
Magnetic suspension train of the present invention is transparent drag reduction road bed when concrete engineering uses, and magnetic-levitation can be fixed on the girder, also can be fixed on the contact beam, and its advantage is:
1, printing opacity, the growth of ground plant health.
2, the turbulent flow of train operation drive is weakened drag reduction by the acute angle damping device.
3, alleviate the weight of overpass, saved material.
