Description
Technical field
The utility model relates to the multi-functional partition wall device in a kind of bus engine cabin.
Background technology
Passenger vehicle overriding noise source is caused by driving engine and annex thereof mostly, as exhaust roar, cooling fan noise, engine mechanical motion noise, roughness noise etc., makes to have higher sound pressure level in the machinery space; And the repeatedly reflection of motor noise surface of steel plate in the cabin forms very strong reverberant sound, must take absorbing treatment; Simultaneously, interior noise, heat will influence travelling people person's traveling comfort into the car through partition wall.So machinery space partition wall design is extremely important, not only will play heat-blocking action, also to have preferably absorb sound, the sound insulation effect.
Yet present numerous bus engines cabin curtain wall structure has mainly played the heat-insulation and heat-preservation effect, and absorb sound, defening effect is not good, causes internal car noise too high.
At present common structure as shown in Figure 1, machinery space skeleton 0 top fixation steel plate 04 is pasted with damping material 03 on the steel plate 04, be coated with bamboo-wood floor 02 and flooring laminate 01 on damping material; Be filled with the heat-preservation cotton 05 with skeleton 0 condition of equivalent thickness in the space between the machinery space skeleton 0, its surface coverage the aluminium foil mask 06 of not perforate, and skeleton 0 below is by the fixing aluminium expanded sheets 07 of peripheral press strip.
Bamboo-wood floor 02 and flooring laminate 01 as interior material, its sound absorption, sound-insulation capability are very weak, and by one deck steel plate 04, one deck damping layer 03, one deck heat-preservation cotton 05 constitute its sound absorption of partition wall, defening effect is also undesirable, as partition wall is carried out acoustic experiment, the result shows, its noise reduction coefficient NRC only is 0.23, and mean transmission loss is 25.3dB (A); Test to the passenger vehicle internal car noise is also found, noise is skewness in car, from the near seat air sound intensity of driving engine, seat far away then solid-borne noise is main, from driving engine near point and the differential 3～5dB (A) that reaches of far point acoustic pressure, so the key that reduces the passenger vehicle internal car noise remains the sound insulation and the vibration isolation of driving engine.
Along with country payes attention to more for controlling machine motor-car noise emission, and the passenger is higher for the requirement of driving comfort, in the design of bus engine cabin curtain wall structure, must reach heat insulation, multiple performance absorbs sound, insulates against sound, to realize the attenuate acoustic noise energy, reduce the propagation purpose of noise outside car, in the car.
