Noise-proof device applied to superconducting high-speed magnetic levitation track
The invention provides an anti-noise device applied to a superconducting high-speed magnetic levitation track, and relates to the technical field of magnetic levitation tracks, the anti-noise device comprises a U-shaped track beam, and a plurality of noise reduction units are arranged on the inner side wall of the U-shaped track beam at intervals; the noise reduction unit comprises an installation body connected to the inner side wall of the U-shaped track beam, an inner cavity is formed in the installation body, air holes are formed in the two ends, in the length direction of the U-shaped track beam, of the installation body, and the air holes are used for communicating the inner cavity with the outside. Vibration airflow enters the inner cavity from the air holes in one side of the installation body and then is led out from the air holes in the other side of the installation body, and the stable noise reduction effect is achieved.
本发明提出了一种应用于超导高速磁浮轨道的防噪声装置，涉及磁浮轨道技术领域，包括U型轨道梁，上述U型轨道梁内侧壁间隔设置有多个降噪单元；上述降噪单元包括连接于上述U型轨道梁内侧壁的安装体，上述安装体内开设有内腔体，上述安装体沿上述U型轨道梁长度方向的两端均开设有气孔，上述气孔用于连通上述内腔体和外界，工作状态下，振动气流从上述安装体一侧的上述气孔进入上述内腔体，再从上述安装体另一侧的上述气孔导出，实现稳定的降噪效果。
