The side noise source of the high-speed railway train is mainly pneumatic noise, namely, the noise is mainly transmitted into the train through side walls, end walls and roofs due to the noise caused by air resistance during high-speed running, so that the side windows of the side walls of the train are required to have enough noise reduction effect. At present, a train side window mainly adopts a sound insulation window, a sound insulation main body of the train side window is mainly hollow glass, the hollow glass adopted by the existing sound insulation window basically can meet the sound insulation requirement, however, a sound insulation mechanism is seldom added for installing the hollow glass on a side window frame of a train, and the whole sound insulation amount of the train side window needs to be further improved.
In order to realize the sound insulation treatment of the window frame, some manufacturers try to add damping particles in the cavity of the window frame, and try to realize noise reduction by friction energy consumption among the damping particles filled in the cavity of the profile. However, such window frames are clearly unsuitable for use in side windows of high speed trains, owing to: the filling of the cavity of the profile with a large amount of damping particles results in a significant increase in the weight of the side window, which is certainly not suitable for high-speed trains with extremely high demands on the weight of the components.
