Detailed description of the invention:
At the drag reduction technology of high ferro train, motor-car, rapid (below be collectively referred to as the high speed trains such as high ferro) exterior applications, it can, by the drag reduction overcoat (3) being arranged on headstock rectification centrum district outside face, become whirlpool drag reduction casing sheets fairing (25) jointly to form with the tool of all compartments outside face.Also by the drag reduction overcoat (3) being arranged on headstock rectification centrum district outside face, whirlpool drag reduction casing sheets fairing (25) can be become with the tool of all compartments outside face; And connector is outside between different compartment, the tool of making becomes whirlpool drag reduction casing sheets fairing cooperatively to form.Can also pass through at nearly all compartment outside face, tool for mounting becomes whirlpool drag reduction casing sheets fairing (25) to carry out drag reduction.Equally also by nearly all compartment outside face, all tool for mounting becomes whirlpool drag reduction casing sheets fairing; Also between different compartment, connector is outside simultaneously, makes tool and becomes whirlpool drag reduction casing sheets fairing cooperatively to carry out drag reduction.
At the drag reduction overcoat that the high speed train forefront outside faces such as high ferro are installed, its most basic structure be by the drag reduction overcoat outer shell (3) moving gap (4) outside admission port (1), surperficial tool gas, ribbed support bar (5), drag reduction overcoat inside internal gas mobile space (6) be mainly to form.As in the front portion of drag reduction overcoat or afterbody admission port (1), installation with gravitation fan (10) for master unit, be then a kind of admission port (1) auxiliary parts carrying out selectivity installation.
The gravitation fan (10) but installed in drag reduction overcoat admission port (1), though be not the component part that must have in drag reduction coating device.But in the front portion of drag reduction overcoat or afterbody admission port (1) inner side, if similar Fig. 2, draw in 22 such gravitation fan (10) is installed, then because the amount of air being entered drag reduction jacket internal by admission port (1) can be increased considerably in pole, and make these enter extremely a large amount of high-speed motion air draughts of drag reduction overcoat, can move in gap (4) from the gas on drag reduction overcoat (3) surface, continuous very fast outside overflow be spouting.So will inevitably because moving in gap (4) outside drag reduction sleeve surface gas, the extremely large quantity of air air-flow that outside constantly high speed is erupted and gone out, the high speed trains such as relative high ferro can be blown on one's face just at a high speed and move and next air draught, extruding is blown outside constantly strongly outwards carrying out, cause its sense of motion that strongly outer moving occurs, thus finally make it almost completely can not with the forward outer surface of the high speed trains such as high ferro, directly contact with each other.So in drag reduction overcoat forefront admission port (1) at the high speed train head positions such as high ferro, as made gravitation fan (10) device, the anterior head position of the high speed trains such as high ferro can be made, than only adopting now conventional fairing profile, the punching press windage realizing very big amplitude elimination windward side is inevitable.Even getting rid of can by the present like this windward side punching press windage also cannot eliminated completely, final reduce more than 50-70% or more be all that tool is possible.
The simultaneously relatively air draught that blows against one's face of the high speed train head such as high ferro, after the drag reduction outer jacket surface by just moving the continuous outwards a large amount of high speed jet in gap (4) from gas, the eddy current state that constantly strongly rotates of headstock direction is pointed to because air-flow can become inner side, nature its subsequently by moving movement backward to Rea car body perimeter (be actually Rea car body constantly forward high-speed motion to the region of the such eddy current of firm formation) after, the air-flow skimming over Rea car body outside can be made again, no longer constantly move from front to back, but eddy current type constantly skims over backward, the drag-reduction effect of Rea car body can be increased considerably in pole further so especially.
At the afterbody in the rearmost part compartment of the high speed trains such as high ferro, although also often by constantly being reduced by car body height, and formation rectification centrum district can be made.But at it in company with the continuous high speed motions forward of whole anterior railway car, at the rear area near rear portion, such afterbody compartment, still can the depression that significantly reduces of mineralization pressure, so to run at high speed motion process at trains such as high ferros, the existence of the very large negative pressure of intensity (relatively normobaric infrabar is actual is exactly negative pressure) that also can produce because of motion, forms very large vacuum suction resistance.Although fairing profile Tail Shape being made as reduced diameter can drag reduction, the possibility of result done like this is only by because of high-speed motion, and the vacuum suction resistance produced reduces sub-fraction.But if similar Figure 22, draw in 23 such, at the outside face in rear portion rectification centrum district, afterbody compartment, afterbody drag reduction overcoat (3) device is installed, then because gap (4) can be moved outside the gas by drag reduction overcoat appearance, continuous a large amount of outside Overflow ejection air stream, offset outside negative pressure resistance, so resistance of motion will inevitably be made to occur to reduce by a larger margin.
In the anterior admission port (1) of high speed train forefront drag reductions overcoat (3) such as high ferro, when installing gravitation fan (10), its power needed for motion, preferably adopts rotative speed electrical motor and so on the driving engine (11) of greatly amplitude adjustment as required to provide.And also by between electrical motor and so on driving engine (11) and gravitation fan (10), making significantly can change the transmission system of kinematic velocity, improve drag reduction overcoat (3) working process to change with high speed train kinematic velocity, and change the change of gravitation fan (10) working process rotative speed, and its quantity that can produce working gas changes alerting ability.Final more than drag reduction 50-70% further or more there is very large possibility equally.
In the inner side of the anterior admission port (1) of the high speed train forefront drag reduction overcoats such as high ferro, may in situation preferably as in Fig. 1-2,21 draw, as far as possible significantly strengthen drag reduction overcoat inside face, and the spacing between the high speed train forward outer surface such as inside high ferro, to make between the high speed train forward outer surface such as drag reduction overcoat and high ferro, form comparatively large inner gas mobile space (6) that can play buffer action.Such being conducive to significantly reduces air after entering drag reduction overcoat admission port (1), inside moving resistance when moving further, and therefore increases substantially the drag-reduction effect of drag reduction overcoat.
And in high speed last vehicle of train rectification centrum districts such as high ferros, during as installed afterbody drag reduction overcoat (3), then required to external eruption gas during afterbody drag reduction overcoat (3) work, that can draw in similar Figure 22 is such, by the outer surface portions in high speed last vehicle of train drag reduction overcoat fronts such as high ferros, make the special admission port (1) that arrives several circular hole, and at the inside line of these special admission ports (1), install and admission port (1) or drag reduction overcoat (3) interconnective gas piping, and based on gravitation fan (10) by gravitational attraction additional-air inlet parts, come jointly for drag reduction overcoat provides gaseousness material required for working process.
In the afterbody rectification centrum district of the high speed trains such as high ferro, during as installed afterbody drag reduction overcoat (3), required to external eruption gas during its work, that also can draw in similar Figure 23 is such, by at the whole of the fronts, high speed last vehicle of train rectification centrum district such as high ferro or nearly all outside faces, make the special admission port of a flat open type of the large loop shaped of tool (1), for drag reduction overcoat provides the material of the gaseousness required for working process.This quadrat method of certain employing also may increase some additional friction, so better not as the special admission port of circular hole formula (1) the method drag-reduction effect making tool gravitation fan (10).
Be arranged on gravitation fan (10) device in the anterior admission port (1) of drag reduction overcoat, its power needed for motion, preferably adopt can as required greatly electrical motor and so on the driving engine (11) of amplitude adjustment rotative speed provide.But also can directly introduce the high speed train sustainer, main engine part rotary powers such as high ferro to drive.
In the drag reduction overcoat most external of the high speed train front and rear portions such as high ferro, made drag reduction overcoat outer shell (3), gap (4) profile is moved outside the gas-liquid on its surface, that can draw in similar Fig. 8 is such, be made as between different ribbon outer shell band, there is no different outer shell bar interband connector (23) completely, but there is complete regular parallel arrange the structure of moving gap (4) outside large length gas.
Gap (4) is moved outside the gas on drag reduction overcoat outer shell (3) surface, that also can draw in similar Fig. 7 is such, be made as between different outer shell band, there is different outer shell bar interband connector (23), outside the equal length ribbon gas that complete regular parallel is arranged, move the structure of gap (4).
Gap (4) is moved outside the gas on drag reduction overcoat outer shell (3) surface, that can also draw in similar Fig. 9-10 is such, at ribbon drag reduction overcoat outer shell (3) outside face, make the distribute regular parallel of different outer shell bar interband connector (23) of tool product shape to arrange and move gap (4) outside gas, thus move gap (4) outside the gas of the drag reduction outer jacket surface made, become and have the little segmentation structure of rule of parallel interval distribution characteristics one by one.
Gap (4) is moved outside the gas on drag reduction overcoat outer shell (3) surface, also drag reduction sleeve surface can be had different outer shell bar interband connector (23), or not there is different outer shell bar interband connector (23), strictly all rules is laterally arranged in parallel and moves the longitudinal band of gap (4) outside gas, is made as tool and is in tilted layout each other the structure of feature.
When installing drag reduction overcoat in the front portion of the high speed trains such as high ferro, that can draw in similar Fig. 1-2 is such, by the outside face of drag reduction overcoat outer shell, and the glass port flush with outer surface anterior with driving compartment etc. of making.Also can by the outer shell of drag reduction overcoat (3) and ribbed support bar (5), the rectification centrum district outside face being all arranged on train forefront is outside, then outside the glass port position of the front portions such as driving compartment, the position concordant with rectification centrum district outside face drag reduction overcoat outer shell installs one deck glass again, to make the air in drag reduction overcoat medial movement, by the gap between two layers of glass, conveying in the drag reduction overcoat rearward still existed further.
At the almost whole outside face of the high speed trains such as high ferro, or in the high speed train such as whole high ferro at anterior drag reduction overcoat rear, external rear face position, the tool installed become whirlpool drag reduction casing sheets fairing, its topmost component part, be by one-tenth whirlpool drag reduction casing sheets (25), jointly form with the installation permanent seat base part (26,28) installing them.But interior flowing gas division board (27), is also that tool becomes within the drag reduction casing sheets fairing of whirlpool, can carries out the constituent elements of crucial importance of selectivity use.
Become in the drag reduction casing sheets fairing of whirlpool at tool, most important constituent elements is its outermost one-tenth whirlpool drag reduction casing sheets (25), the profile of one-tenth whirlpool drag reduction casing sheets although it is so, as the author 201410393140.x, 201410460546.4, in 201410529048.1 patent applications as described in, the resemblance that many kinds are not identical can be made as.And the one-tenth whirlpool drag reduction casing sheets of these different profiles, all can become in the drag reduction casing sheets fairing of whirlpool to make for realizing drag reduction object at tool.But there is most the one-tenth whirlpool drag reduction casing sheets profile of practicality, probably or as in illustrations 11-16 draw, the resemblance being made as complete rectangle may be better.
Become in the drag reduction casing sheets fairing of whirlpool at tool, although for the installation permanent seat base part (26,28) being mounted to whirlpool drag reduction casing sheets (25), can there is bar-shape that permanent seat (26) is installed, with discrete, the large type structure of permanent seat (28) two is installed, but they are all the pedestal base parts that may be used for installing outside one-tenth whirlpool drag reduction casing sheets (25), and it becomes the installation method in the drag reduction casing sheets fairing of whirlpool to be also identical at tool.This two class installs the difference between permanent seat base part (26,28), whether be only to be fixed into whirlpool drag reduction casing sheets by install, originally should be the installation permanent seat base part of discrete one by one, by increasing considerably length, and be interconnected to the completely even or integraty belt structure heterogeneous of thickness.
As for becoming at concrete tool in the drag reduction casing sheets fairing of whirlpool, although can draw in similar Figure 11-13 such, will become whirlpool drag reduction casing sheets (25), and be fixed on discrete and install outside permanent seat (28).That also can draw in similar Figure 14-16 is such, adopts bar-shape to install permanent seat or similar device with it, fixes one-tenth whirlpool drag reduction casing sheets (25) in outside.
If from increasing into whirlpool drag reduction casing sheets (25), the structural stability aspect of installation and use process is considered, should be best to adopt the bar-shape drawn in similar Figure 14-16 to install permanent seat (26).If but from the viewpoint of improving the drag-reduction effect of fairing, the installation permanent seat class device being fixed into whirlpool drag reduction casing sheets is then installed, should be adopt discrete in class Figure 11-13 to install permanent seat (28) or by the one-tenth whirlpool drag reduction casing sheets outside fairing, the discrete be arranged near outermost near top installs permanent seat drag-reduction effect may be better.
In the anterior rectification centrum district of the high speed train such as high ferro, and in drag reduction overcoat rear, external rear face, made tool becomes whirlpool drag reduction casing sheets fairing.That can draw in similar Figure 11-13,15-16 is such, is fixed on becoming whirlpool drag reduction casing sheets the outer surface portions that any one installs permanent seat (26,28).That also can draw in similar Figure 14 is such, the near top position that permanent seat (26,28) outermost is seldom measured will be installed, extend to into outside the drag reduction casing sheets of whirlpool, the class ribbon making lateral length larger becomes whirlpool drag reduction casing sheets, is divided into the strip one by one that length is relatively short.To improve the structural stability that the high speed train appearance institute tool for mountings such as high ferro become whirlpool drag reduction casing sheets fairing.
At positions, rectification centrum district of high speed train head such as high ferros, or headstock install in the train at drag reduction overcoat rear, external rear face position, carry out making or install the fixing rear tool used and become whirlpool drag reduction casing sheets fairing, can as in Figure 11-16 draw, line up between the drag reduction casing sheets of whirlpool compared with the difference of Large space at the mutual tool in air motion direction, install interior flowing gas division board (27) additional.Also interior flowing gas division board (27) can not be installed additional at such position, interval.May to line up the position, interval between the drag reduction casing sheets of whirlpool in such difference of fairing outside face, when adding interior flowing gas division board (27), drag-reduction effect may be best.
Interior flowing gas division board (27) tool become install in the drag reduction casing sheets fairing of whirlpool time, interior flowing gas division board (27) uppermost margin like this, should be slightly closer from one-tenth whirlpool drag reduction casing sheets (25) Edge Distance in its front, and away from one-tenth whirlpool drag reduction casing sheets (25) Edge Distance at its rear some.So just gaseous matter can be caused, enter inner side gas mobile space (32) time inflow entrance (35) larger, and gas-liquid overflow inner side gas mobile space (32) time flow export (34) relatively smaller.Thus extraneous gas material can be made, and more convenient when flowing into from position, drag reduction casing sheets front and back, the one-tenth whirlpool opening in fairing or flow out, also make fairing can realize better drag-reduction effect simultaneously.
The kinematic velocity of the high speed trains such as high ferro is higher, the tool making at its outside face or install and use becomes whirlpool drag reduction casing sheets fairing, the difference of its sense of motion lines up the spaced distance between the drag reduction casing sheets individuality of whirlpool, and what just should make is more relatively larger.The air-flow caused to adapt to improve with kinematic velocity, gas mobile space (32) inside fairing, quantity when moving constantly increases feature fast.
Because the high speed Train motion speed such as same principle high ferro are faster, at Rapid train compartment outer surfaces such as these high ferros, the tool installed becomes within the drag reduction casing sheets fairing of whirlpool, become whirlpool drag reduction casing sheets (25) and the spacing distance inside it between car body outside face, what also should make wants more relatively large.By inner side gas mobile space (32) between both increases highly, to promote that the flowing velocity of air-flow in inner side gas mobile space (32) improves carrying out drag reduction.
The high speed train outside faces such as this external high ferro, the tool installed becomes in the drag reduction casing sheets fairing of whirlpool, suitably increasing into whirlpool drag reduction casing sheets (25), and after the spacing distance between the car body outside face inside it, also can become inner side, whirlpool drag reduction casing sheets (25), various installation permanent seat (26,28) base part outside face and the car body outside face in inside, the specific drag reduction paste layer (29) of some different profiles is all installed.And in inner side gas mobile space (32) becoming whirlpool drag reduction casing sheets, some different outer form drag bodies (36) are set.Cause like this in inner side gas mobile space (32), increase considerably the friction drag of gas movement, be in fact conducive to increasing substantially tool and become whirlpool drag reduction casing sheets fairing drag-reduction effect.
Become inside the drag reduction casing sheets of whirlpool in gas mobile space (32), the resistance body (36) installed; And become inside whirlpool drag reduction casing sheets, permanent seat base part outside face and inside car body outside face be installed, the drag reduction paste layer (29) installed.Their anterior windward side (namely they are with the rear portion, direction of a Train motion) side surface, should be made as and can increase considerably gaseousness material, and in gas mobile space (32), motion process increases any profile of resistance of motion.But at they rear portion lee face one side external surfaces, then should make can the milder fairing shape profile of significantly drag reduction.Stronger counter motion resistance (being the thrust can offsetting real resistance in fact) object must be produced to realize it.
In order to carry out drag reduction to greatest extent, between the compartment being interconnected position between the different compartment of the high speed train such as high ferro, connector (18) is outside, also can make tool and become whirlpool drag reduction casing sheets fairing (25).
But because the author is to connector (18) between the compartment between the different compartment of the high speed trains such as high ferro, how interconnective concrete structure is not clear between different compartment, so the tool drawn in Figure 24-27 becomes whirlpool drag reduction casing sheets fairing (25), structurally there is certain imagination, but except connector between compartment (18), by Rotatable mounting support (20), be interconnected rib (21), S. A. (47), the two torque spring (22) of tool shell protection, become whirlpool drag reduction casing sheets (25) five major part, the rotatable tool of common formation becomes whirlpool drag reduction casing sheets fairing, the author think structure be substantially comparative maturity can application structure.
As for connector (18) structure between the compartment between different compartment, and the connection between itself and compartment between connector (18), although the author also cannot accurately draw now, no matter but their profile with figure in drawn much differences, the rotatable tool drawn in Figure 24-27 becomes whirlpool drag reduction casing sheets fairing, its structure may all not need to carry out large amendment, so the author thinks that the interior rotatable tool drawn of Figure 24-27 becomes whirlpool drag reduction casing sheets fairing, tool that exactly can be practical becomes whirlpool drag reduction casing sheets fairing.
At high speed train outside face or anterior region such as high ferros, after the drag reduction overcoat (3) of tool for mounting admission port (1), because moving the outer shell surface between gap (4) outside the different adjacent gas of drag reduction sleeve surface, lower in the front height of sense of motion, the class fairing formula profile that rearward height is higher, so enter the gaseousness material within drag reduction overcoat from admission port (1), can be as interior in Figure 28 draw, move gap (4) outside gas constantly by drag reduction overcoat outer shell (3) surface and carry out effusive eruption, thus it is outside at drag reduction overcoat outer shell (3), forming inner side is comparatively slow nearly horizontal rearward movement gaseousness material layer, secondary internal layer is eddy current (45) property motion material layer, outside is only the feature of carrying out high speed relative motion approximately level gaseousness material layer again.Such nature will cause extraneous gas material, is almost again directly to contact with each other with Rapid train compartment outer surfaces such as high ferros, is inevitable so can carry out significantly drag reduction.
And all car body outside faces at rear, the high speed trains such as high ferro anterior head position rectification centrum district, and in all compartments at drag reduction overcoat rear, head position, external rear face, after tool for mounting becomes whirlpool drag reduction casing sheets fairing, because of a large amount of gaseousness materials, can be as interior in Figure 29 draw, in a large number from becoming whirlpool drag reduction casing sheets anterior and interior flowing gas division board (27) rear, after gaseousness Commodity flow entrance (35) enters in a large number, again from becoming drag reduction casing sheets rear portion, whirlpool and interior flowing gas division board (27) front, gaseousness material flow outlet (34) effusive eruption and going out, thus equally also whirlpool drag reduction casing sheets fairing can be become outside at tool, forming inner side is comparatively slow nearly horizontal motion gaseousness material layer, secondary internal layer is eddy current (45) property motion material layer, outside is only the feature of carrying out at a high speed relative motion gaseousness material layer again, such nature will cause the gaseousness material of its outside, directly can not contact with each other with high speed train outside faces such as high ferros again, so can significantly also be inevitable by drag reduction.
