Specific embodiment
The typical road of China is other than the asphalt pavement road surface that urban road and super highway use, in city suburbs
It is based on cement road with rural area.Meanwhile in order in partial region regulation speed or anti-skidding, meeting setting deceleration on road surface
Band or cutting.The form of the deceleration strip of Chinese road occupation is different from the crosspiece road surface that foreign countries use.Further, since road is long
Abrasion after time use, in some areas, there is also the road surfaces that greater number of rough road or height rise and fall.
Fig. 1 discloses the floor plan in the vehicle vibration noise comfort test road of an embodiment according to the present invention.
The present invention proposes a kind of vehicle vibration noise comfort test road, comprising: acceleration region 102, test along direction of traffic arrangement
Region 104 and decelerating area 106.It can have the test roads of one or several parallel arrangement in test area 104.It is illustrating
Embodiment in, acceleration region 102 and decelerating area 106 also can be divided into the road of one or several parallel arrangement, and
And docked with the road in test area 104, so that each road in test area 104 can have the acceleration of oneself
Section and braking section.In other examples, acceleration region 102 and decelerating area 106 can not divide road, and use whole
Mode.Vehicle accelerates in acceleration region 102, then drives into a certain road in test area 104, then drive into deceleration area
Slow down in domain 106.
The type of test roads in test area 104 is determined according to the typical road conditions of vehicle using area.Test roads
Length determined according to preset vehicle speed and time of measuring.In one embodiment, according to be analyzed above China typical road conditions,
The type for determining test roads includes: deceleration strip road surface, cutting road surface, coarse bituminous pavement and wave bumpy road.It is illustrating
Embodiment in, coarse bituminous pavement 141, deceleration strip road surface 142, cutting road surface 143 and wave bumpy road 144 are by parallel cloth
It sets.It should be noted that 104 test roads are at least one in mentioned kind in test area.In difference
Application in, can according to need selection mentioned kind one of which, two kinds, three kinds or be all arranged.Arrangement
Sequence also can be set as needed, it is shown in FIG. 1 be used for the purpose of for example, not the present invention is made it is enforceable
Limitation.
In one embodiment it would be required that vehicle is travelled in test area 104 with the preset vehicle speed of 80km/h, with test compared with
Noise situations under high speed.Test road because the sampling of test noise needs the regular hour, in test area 104
Road needs enough length, allows the vehicle to travel time enough with the speed of 80km/h.In one embodiment, according to
It calculates, the length of test roads is not less than 300m.For the length of acceleration region 102 and decelerating area 106, then its length is required
Degree enables to vehicle that can accelerate to 80km/h before entering test area, and stopping can be decelerated to by 80km/h.
Refering to what is shown in Fig. 2, Fig. 2 is disclosed in the vehicle vibration noise comfort test road of an embodiment according to the present invention
The cross section structure on deceleration strip road surface.Deceleration strip road surface is cement pavement, is disposed at least one deceleration strip on cement pavement, is slowed down
The section of band be it is trapezoidal or parabola shaped, the section bottom width W of deceleration strip is 300mm~400mm, and the section of deceleration strip is high
Degree H is 30mm~60mm.As needed, a deceleration strip, or the several deceleration strips of arrangement can be arranged on cement pavement.Number
A deceleration strip can be equidistantly spaced from, and can also be arranged with unequal interval, and in some embodiments, several deceleration strips can also omit
It is micro- to be staggeredly arranged.Deceleration strip road surface is mainly used for virtual community, school, enterprises and institutions, backroad, ramp, charge station etc.
The deceleration strip being arranged on road surface.
Fig. 3 discloses section on cutting road surface in the vehicle vibration noise comfort test road of an embodiment according to the present invention
