Vibration and noise reduction shielding door of urban rail transit station platform
The invention provides a vibration and noise reduction shielding door for an urban rail transit station platform, which belongs to the technical field of shielding doors for subway stations. The shielding door comprises a sunken structure, which is arranged on the surface of the shielding door according to the type, the material and the size of the shielding door in combination with a main frequency band needing noise reduction. By reducing the vibration of the shielding door, radiation noise, caused by vibration, of the shielding door is reduced, and the stability and firmness of the shielding door are improved; therefore, resonance is avoided or reduced, and then vibration of the shielding door is weakened; radiation noise generated in the subway station is reduced, the sound environmentcondition of the platform layer is improved, the vibration of the shielding door is weakened, the interaction force between the shielding door and the ground of the platform layer is also reduced, and the firmness and stability of the shielding door are improved; the periodic sunken structures have elastic wave band gaps, so that free propagation of elastic waves is weakened.
本发明提供一种城市轨道交通车站站台减振降噪屏蔽门，属于地铁车站站台屏蔽门技术领域，包括根据所述屏蔽门的类型、材料及尺寸，结合需要降噪的主频频段，在屏蔽门表面设置凹陷结构。本发明通过减少屏蔽门的振动降低了由振动引起的屏蔽门辐射噪声并增加了屏蔽门的稳定性和牢固性；避免或减少产生共振，进而减弱屏蔽门的振动；减少了对地铁站内产生的辐射噪声，站台层的声环境状况得到改善，屏蔽门振动的减弱也减少了其与站台层地面连接处的相互作用力，提高了屏蔽门自身的牢固性与稳定性；周期性的凹陷结构具有弹性波带隙，减弱了弹性波的自由传播。
