Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Should be noted that, " connection " described in the application and the word for expressing " connection ", as " being connected ", " being connected " etc., it both can refer to a certain parts with another parts and directly be connected, and also can refer to a certain parts and was connected with another parts by miscellaneous part.
By simulation Bing Mian road driver training, driver can under the specific condition of Bing Mian road to gear, turn to, to brake and accelerator pedal correctly, expertly uses, the essential characteristic of driving on Bing Mian road, correct operation, the harm of faulty operation and counter-measure can be grasped.
As shown in Figure 1, it is three floor that the application simulates Bing Mian road basic structure: high-strength imitated ways coating materials floor, thick 1.5mm, and dope layer is blocked up easily causes be full of cracks and peeling, facts have proved that 1.5mm is proper thickness, and construction technology can reach this requirement; Hardened layer, i.e. C30 Portland Cement Concrete Surface Course, thick 200mm; 37 lime earth basic unit, thick 300mm.Element soil (or soil matrix) compacting under 37 lime earth layer, degree of compaction >=93% within the scope of 0 ~ 800m.
As shown in Figure 2, the integral linear on simulation Bing Mian road is annular, is made up of two sections of straight roads, one section of detour and one section of ramp detour.Be set to the wearing and tearing that round is convenient to train and reduce dope layer.
Simulation Bing Mian road total length is not less than 300m, wherein straight road is not less than 80m (two sections), detour is not less than 70m, ramp detour is not less than 70m, width is not less than 8m and (can accelerates to certain speed on straight road, then brake, know from experience the sideslip that faulty operation causes, still remain on road surface when ensureing defective steering stabilizer, ensure training of safety).
The radius of horizontal curve value of ramp detour is for being greater than 15m, and 15m is the Limit infinitesimal radium of heavy mound, Class IV highway mountain ridge landform.
The transverse slope i of ramp detour
h≤ 6%, by relevant highway technical standard regulation, there is highway transverse slope that is freezing or snow-up terrain, should not 6% be greater than, according to formula R>=V
2/ 127 (f+i
h), the radius of horizontal curve of R ramp detour, f is attachment coefficient, f value 0.2, i
hvalue 6%, R value is 15m, by R>=V
2/ 127 (f+i
h), obtain
for ensureing that the unlikely generation of vehicle travelled on detour is surveyed sliding, the vehicle velocity V that vehicle travels on the detour of ramp should be met:
I
hfor the transverse slope of ramp detour, its value is i
h≤ 6%, R is radius of horizontal curve, its unit is the unit km/h of m, V, calculates V≤22km/h, work as V>22km/h, vehicle will break away, and when land area allows, can consider suitably to increase radius of horizontal curve, like this, the max. speed of vehicle by this section can be improved.
The top rake i of ramp detour
z.When vehicle travel on Bing Mian road reach max. climb slope time, meet Gcos θ f=Gsin θ, G is the gross weight of vehicle, and unit N, θ are the angle of slope of road surface along direction of advance, and f is attachment coefficient.By G2cos θ f=Gsin θ, obtain f=tg θ=i', at this moment attachment coefficient f value is equal with maximum climbable gradient of vehicle i', and namely the max. climb slope i' of vehicle on Bing Mian road depends on attachment coefficient f.The top rake i of the design ramp detour
zmust be less than the max. climb slope i' of vehicle on Bing Mian road, namely be less than f value, vehicle could go up a slope.F value 0.2, so at this moment the max. climb slope i' of vehicle is 20%.On normal road surface, the max. climb slope of vehicle depends on vehicle technology performance.The max. climb slope of vehicle on simulation Bing Mian road is much smaller than the max. climb slope on normal road surface.For ensureing normal training, the top rake i of ramp detour in the design
zbetween 5% ~ 10% (maximum longitudinal grade of speedway is 5%, and the maximum longitudinal grade of Class I highway is 6%, and the maximum longitudinal grade of Class II highway is 7%, and the large longitudinal gradient of getting of Class III highway is 8%, and the maximum longitudinal grade of Class IV highway is 9%).
There is the safe distance that at least 2m is wide outside the tooth of road, overturn after preventing defective steering stabilizer from skidding off road surface.
Entrance arranges a pond, and length is greater than 1 times of wheelbase, wide 6 ~ 8m, and effect is before vehicle sails simulation Bing Mian road into, cleans, shields to dope layer, extend the application life on simulation Bing Mian road to tire.For making road surface closer to true Bing Mian road and increasing training difficulty, rut road and section, convex closure road are optionally established in Bing Mian road in simulation.
Gutter is established, ditch depth 400mm, wide 400mm in simulation both sides, Bing Mian road, on establish cover plate, cover plate height is consistent with upper road surface height, establishes feed pipe and shower nozzle in gutter, and the upper road surface outside gutter in safe distance is consistent with simulation Bing Mian road upper level.
Establish road tooth outside gutter, effect prevents vehicle from skidding off road surface.Road tooth height must not higher than the minimum ground clearance of training vehicle used.The height of road tooth is 100mm.
The effect of water spray system makes simulation ice face road surfaces have certain thickness moisture film, keeps low attachment coefficient.Ordinary circumstance Imitating Bing Mian road rain water depth on road surface is optimum state with 2mm, and rain water depth on road surface is too small, there is larger frictional force between vehicle tyre and road surface, can reduce road surfaces smoothness; Excessive, can form certain resistance to vehicle tyre, vehicle even may produce a kind of drift phenomenon, all can not embody the time of day on low attachment coefficient road surface.
Water spray system is made up of parts such as water pump, water tank, feed pipe, shower nozzle, control device.Water tank is arranged 8 switches, the independent tubes of each switch control rule 75m, every bar pipeline assembles 7 shower nozzles.28 shower nozzles are respectively arranged in road both sides, and the shower nozzle interlaced arrangement on both sides, approximately every 5m arranges 1 shower nozzle, and shower nozzle has multiple little spray orifice, and water becomes divergent shape after shower nozzle ejection.Control device controls the power supply of water pump.
There is important impact in the life-span of O&M at ordinary times on simulation Bing Mian road, should note proper use of, must spray water as surface and well could use, and note the maintenance in simulation ice face, as kept surface cleaning, keeping the clean wearing and tearing etc. alleviated simulation ice face of vehicle tyre.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
