Abstract
The utility model provides a device for improving train running condition, which adds a nose cone at the locomotive head and a tail cone at the last carriage on the basis of the prior carriage, so as to reduce windward resistance and trailing vortex negative pressure resistance. The carriage roof adopts wing shape to generate a lifting force to reduce friction between the carriage and the rail, and other pointed, protruding and thick parts are covered by a fairing to reduce resistance. With the measures, the original resistance can be reduced by more than 25 percent, so as to increase vehicle speed and save fuel.
Description
The utility model is in order to improve the device of train running situation.
At present, some train contacts with air with rectangle headstock, rectangle compartment and arc carriage top, and this situation produces very big resistance to train vibration influence, and is unfavorable with the fuel saving and the raising speed of a motor vehicle.If will change the status quo new design must be arranged.
The utility model " aerofoil profile train " is that aeronautical engineering technology and aerodynamics groundwork are applied on the railway transportation.The external bullet train that occurs, magnetic suspension train is exactly an illustration.The aerofoil profile data of dopey are very ripe, are applied on the train very favourable.
The purpose of this utility model is achieved in that adding a fairing (nose cone) in the locomotive head front fills the higher-pressure region, front, makes locomotive head near becoming stream line pattern, in order to reduce frontal resistance.Replace present circular arc carriage top (dopey aerofoil profile) with the aircraft airfoil structure, the compartment can produce lift under steam, the corresponding minimizing of the friction force of wheel and rail.Back, train final section compartment adds a tail cup (tail cone) and fills the afterbody vortex region, and the afterbody resistance reduces.Be exactly in addition outstanding, the wedge angle in locomotive and compartment, coarse position are become round-corner transition or its smooth rectification is wrapped, cover gets up.Above measure makes " aerofoil profile train " reach the purpose of energy-conservation speed-raising.
The utility model can reach the train fuel saving to be improved speed, reduces rail wear, alleviates the promising result that roadbed damages, favourable to roadability simultaneously, can also reduce noise.
Carriage top is changed into airfoil structure, is the characteristics of this utility model.Learn that from aeronautical theory airfoil structure produces lift in the air of motion.The compartment will alleviate for the pressure of rail, and rolling frictional resistance reduces.
Aerodynamic lift formula: Y=Cy1/2 ρ V

Y---lift coefficient, determine by the air foil shape and the angle of attack.
P---density of air is 0.125 kilogram of second

For example: long 27.40 meters of compartment, wide 2.20 meters, blade area is about 54.34 meters

60 kilometers/hour of the speed of a motor vehicle, then compartment lift Y=942 kilogram
Select the suitable aerofoil profile and the angle of attack for use, C
YValue can be greater than 1, and lift also can increase.The wing of dopey is by friction drag, and pressure drag and induced drag constitute total resistance.Wherein friction drag and the pressure drag calculation of can ignoring.Induced drag and aspect ratio are in close relations, for reducing induced drag, wing fence are installed in the aerofoil profile both sides, in order to intercept the lateral airflow influence.
(1) is connected with locomotive for nose cone (fairing) adopts aluminum alloy to be streamline contour among the figure, has observation window to guarantee visual field on nose cone top.(2) for guaranteeing lift, realizes airfoil structure.(3) wing fence is used for intercepting the inside and outside air-flow of aerofoil profile and links up, and guarantees good lift effect.(4) be tail cone (tail cup), be used for improving afterbody meiobar situation, reduce the afterbody resistance.(5) compartment envelope.
Aerofoil profile firmly is connected with the compartment, and wing fence is installed in the aerofoil profile both sides.Fairing (nose cone, tail cone) and locomotive and compartment bolt together are convenient to change.The actual conditions design is looked in other measure that reduces resistance.
Claims (1)
- A kind of train is linked in sequence by locomotive, compartment and wheel, it is characterized in that: add both front fairings of nose cone before locomotive; Carriage top replaces to airfoil structure; Wing fence is installed in the both sides of airfoil structure; Behind the afterbody compartment, add both tail cups of tail cone.
