Abstract

The invention discloses a sound insulation system, a passenger room door, a guide groove of a rail traffic vehicle and the rail traffic vehicle. The sound insulation system comprises a vehicle door and the guide groove. The bottom of the vehicle door is provided with a groove. The guide groove is provided with a sunken part matched with the bottom of the vehicle door in width. The sunken part is internally provided with a protruding strip matched with the groove in shape and size. The portion, between the top end of the protruding strip and the vehicle door, of the groove and the space between the bottom end of the vehicle door and the sunken part on the sides of the protruding strip are filled with sound absorption materials. According to the sound insulation system, three sound absorption structures are arranged on a sound passing path; sound waves go into the sound absorption materials through small holes of pore plates, sound energy is consumed a lot, sound leakage can be greatly relieved, and the sound insulation property so the vehicle door is further improved.

Description

technical field [0001] The invention relates to the rail transit field, in particular to a rail transit vehicle sound insulation system, a passenger compartment door, a guide groove and the rail transit vehicle. Background technique [0002] Rail transit vehicles, as a mass public transportation tool with large capacity, fast, safe, punctual, energy saving and environmental protection, have become an important part of public transportation in large and medium-sized cities. With the opening of rail transit lines in various large and medium-sized cities, people are paying more and more attention to the noise of the driver's space, and their requirements are getting higher and higher. [0003] Under normal circumstances, the largest noise sources of rail transit vehicles mainly come from the wheel-rail noise under the vehicle and the noise of the traction drive system. During the transmission of noise under the car, it encounters the car body, car windows and car doors, part o...
