Description
Technical field
The present invention relates to field of track traffic, particularly a kind of rail traffic vehicles sound partiting system, guest room door, guide groove and rail
Road vehicular traffic.
Background technology
Rail traffic vehicles as a kind of large conveying quantity, quick, safety, on schedule, the popular public transport works of energy-saving and environmental protection
Tool, has become the important component of each big-and-middle-sized urban public transport.As rail line is in each large- and-medium size cities
Open-minded successively, people multiply the noise attention rate more and more higher in space to department, it is desirable to also more and more higher.
Generally, wheel track of the maximum noise source under car when rail traffic vehicles are run on the line is made an uproar
Sound and traction drive noise.Car body, vehicle window and car door are run under car in noise transmittance process, a part is blocked in outside car
Referred to as oise insulation factor, another part is delivered in guest room by car body, vehicle window and car door.Influenceed by slit source sound, outside car
Noise, by the incoming in-car in gap, is one of weak link of internal car noise control.
Under normal circumstances, door leaf bottom is provided with sliding guide groove, door leaf is sliding in guide groove in the presence of drive mechanism
It is dynamic.Because in door leaf insertion guide groove, the noise outside car can not be delivered to in-car on propagation path along straight line, in communication process
Propagated first along the direction parallel to gap outdoors, the door leaf rear portion sound wave for running into embedded guide groove is reflected, a part of sound
The ripple change direction of propagation bypasses door leaf bottom and undergoes triple reflection again and travel to in-car after changing direction.This method can stop
A part of incoming in-car of noise, is due to that propagation path is simpler, although noise is reflected a part but major part is made an uproar
Sound has still traveled to in-car, and noise reduction is not obvious, and car door leaks voice phenomenon still than more serious, it is impossible to reach the mesh of noise reduction
's.For the guest room door of this use guide rail form, its defening effect how is lifted, reduces leakage volume, is rail traffic vehicles
In-car noise reduction needs the technical barrier solved.
The content of the invention
The technical problems to be solved by the invention are, poor for defening effect caused by current track Vehicular door leakage sound
The problem of there is provided a kind of rail traffic vehicles sound partiting system, guest room door, guide groove and rail traffic vehicles.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of rail traffic vehicles sound partiting system,
Including car door and guide groove；The car door bottom opens up fluted；The guide groove is provided with what is matched with the car door bottom width
Provided with the raised line matched with the groove shapes size in sunk part, and the sunk part；The raised line top and the car
In groove between door, sound-absorbing material is filled between the sunk part of the car door bottom and the raised line both sides.
Sound-absorbing material in the groove, sunk part is respectively covered and fixed by orifice plate so that system architecture is more steady
Gu, prevent sound-absorbing material from coming off.
Correspondingly, present invention also offers a kind of rail traffic vehicles guest room door, its car door bottom opens up fluted；It is described
Sound-absorbing material is filled with groove.
The sound-absorbing material is covered and fixed by orifice plate, prevents sound-absorbing material from coming off.
Correspondingly, rail traffic vehicles guide groove of the invention is provided with the depressed part matched with above-mentioned car door bottom width
Point, and provided with the raised line matched with the groove shapes size in the sunk part；In the sunk part of the raised line both sides
Filled with sound-absorbing material.
The rail traffic vehicles of the present invention include above-mentioned sound partiting system.
Meanwhile, rail traffic vehicles of the invention can use the guest room door of said structure.
The above-mentioned guest room door of correspondence, rail traffic vehicles of the invention use above-mentioned guide groove.
Orifice plate in the present invention, refers to open up foraminate plate, and optimal aperture chi is selected according to the frequency size of noise
Very little, in the present invention, the aperture of aperture takes 2-8mm.
Compared with prior art, the advantageous effect of present invention is that：Sound is relative through the guide rail structure of the present invention
Common car door gap path is more complicated, and sound wave needs to get to in-car by multiple reflections and sound absorption link, can be with more
Acoustic energy is lost in ground, reduces leakage sound, improves the sound insulation property of car door；The present invention is provided with three sound absorptions in sound passage path
Structure, sound wave is entered in sound-absorbing material by the aperture of orifice plate, and acoustic energy can greatly reduce leakage sound by substantial amounts of consumption,
Further improve the sound insulation property of car door.
Brief description of the drawings
Fig. 1 is one embodiment of the invention structural representation.
Embodiment
As shown in figure 1, sound partiting system of the present invention includes car door 1 and guide groove 2；The bottom of car door 1 opens up fluted 3；Institute
State guide groove 2 be provided with the sunk part 4 that match with the bottom width of car door 1, and the sunk part 4 provided with and the groove
The raised line 5 of 3 shape sizes matching；In groove 3 between the top of raised line 5 and the car door 1, the bottom of car door 1 and institute
State and sound-absorbing material 6 is filled between the sunk part 4 of the both sides of raised line 5.
First in door leaf（Car door）Bottom processes a groove, and the filling sucting sound material in groove, sound-absorbing material passes through hole
The covering of plate 7 is fixed.Guide groove, which is processed into the middle of as shown in Figure 1, projection（Raised line）The form of grooves of guide rail, in guide rail both sides
Filling sucting sound material in groove, and cover fixation with orifice plate respectively.Guide groove and guest room door system are arranged on the corresponding position in guest room
Put.
After installation, noise outside the car more common guide groove on propagation path is more complex, time that noise is reflected
Number is twice of common guide groove order of reflection.Noise outside car runs into car door rear portion and reflected, and another part is along gap
Down propagate；Run on the outside of groove that noise is divided into three parts after orifice plate, Part I noise is reflected, and Part II noise enters
Enter by the sound-absorbing material absorption inside orifice plate in orifice plate, Part III noise changes direction and continues to propagate along gap；Continue to pass
The guide rail rear portion that the noise broadcast runs into projection continues on gap propagation by reflection another part；The noise for continuing to propagate exists
Run into after the orifice plate in car door and be divided into three parts, Part I noise is reflected, Part II noise enters quilt in orifice plate
Sound-absorbing material inside orifice plate absorbs, and Part III noise changes direction and continues to propagate along gap；The noise for continuing to propagate is met
Gap is continued on to door leaf medial surface rear portion by reflection another part to propagate；The noise for continuing to propagate is being run into groove
It is divided into three parts again after the orifice plate of side, Part I noise is reflected, Part II noise enters in orifice plate by inside orifice plate
Sound-absorbing material absorb, Part III noise change direction along gap continue propagate；The noise for continuing to propagate is run into groove
Side rear portion is reflected, and another part is along the incoming in-car in gap.In experience so complicated noise transmission path and many
After secondary sound absorption link, the noise for traveling to in-car by guide barrel construction is significantly reduced.By the invention it is possible to effectively subtract
Small guide groove slit source sound, the defening effect of lifting guest room door, and then the in-car noise level of effective control.
