Abstract
The utility model relates to a rail train wall structure which comprises a main wall body and an interior trim board which is arranged on the inner side face of the main wall body. A sound absorption board is arranged between the main wall body and the interior trim board, and the sound absorption board and the inner side face of the main wall body are connected through a mucilage layer provided with damping material. The rail train wall structure not only can increase the effective sound absorption area in a train room, but also can effectively reduce vibration sound radiation of the surface of a wall, and thus the comprehensive noise reduction performance of a train wall is promoted.
Description
Technical field
The utility model relates to a kind of track train wall body structure.
Background technology
The car body of train is in order to reduce indoor noise, and various piece has all been carried out multi-form acoustic treatment.Cotton as between main wall body inside face and trim panel, filling winter protection, can play on the one hand the effect of sound insulation and sound absorption, can improve on the other hand the heat-proof quality of body of wall.
But the indoor noise of track train is except air borne sound, also have structure-borne sound and structural vibration radiated sound, because the main wall body is generally metal thin plate structure, if not carrying out suitable damping, the surface do not process, then inevitably can be in vibration processes the radiation vibration noise, the winter protection cotton of filling then can not be worked to this kind noise.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of track train wall body structure, can be simultaneously the noise of outdoor noise and main wall body generation of vibration be played sound insulation and sound absorption.
The technical solution of the utility model is, a kind of track train wall body structure, comprise the trim panel of main wall body and main wall body medial surface, be provided with sound-absorbing panel between described main wall body and the trim panel, sound-absorbing panel is connected by the adhesive-layer with damping material with main wall body medial surface.
Described sound-absorbing panel is waveform near the end face of trim panel, and fits with trim panel.
Sound-absorbing panel is the waveform surface near the end face of trim panel, can increase effectively sound absorption area; The end face of the close main wall body medial surface of sound-absorbing panel is plane form, by the adhesive layer with damping material sound-absorbing panel is sticked on main wall body inside face, and the damping that can increase the wall thin sheet surface reduces the chatter radiation.
As known from the above, the utility model is as a kind of track train wall body structure, and this structure can increase the indoor effective sound absorption area of train, can effectively reduce again the chatter radiation of surface of wall, thereby improves the whole anti-acoustic capability of train body of wall.
Description of drawings
Fig. 1 is the longitudinal cross-section schematic diagram of track train wall body structure described in the utility model.
The specific embodiment
As shown in Figure 1, a kind of track train wall body structure comprises the trim panel 4 of main wall body 1 and main wall body 1 medial surface being provided with sound-absorbing panel 3 between described main wall body 1 and the trim panel 4 that sound-absorbing panel 3 is connected by the adhesive-layer 2 with damping material with main wall body 1 medial surface.
Sound-absorbing panel 3 is waveform near the end face of trim panel 4, and fits with trim panel 4.
