The invention discloses a track vibration isolator and method. The track vibration isolator structurally comprises a concrete track bed connecting block, a vibration isolator main body, a vibration isolator supporting base plate, reinforcing ribs and concrete track bed supporting columns, wherein the vibration isolator supporting base plate is horizontally installed on the track ground, and the vibration isolator main body is perpendicular to the vibration isolator supporting base plate; the reinforcing ribs are welded together with the vibration isolator main body and the vibration isolator supporting base plate, and the track vibration isolator is provided with a magnetorheological fluid uniform distribution structure, so that when a subway runs again after being stopped for a long time, and when the vibration isolator works, ferromagnetic particles in the vibration isolator are uniformly mixed with bearing fluid through the combination of shear mixing and centrifugal force mixing; the damping force of the vibration isolator in use is guaranteed, the performance of the vibration isolator is improved, the vibration isolator is prevented from being damaged due to uneven mixing of iron tooth particles and bearing liquid, and the service life of the vibration isolator is prolonged.
本发明公开了一种轨道隔振器及方法，其结构包括混凝土道床连接块、隔振器主体、隔振器支撑基板、加强筋、混凝土道床支撑柱，隔振器支撑基板水平安装于轨道地面上，隔振器主体与隔振器支撑基板相互垂直，加强筋与隔振器主体、隔振器支撑基板焊接在一起，轨道隔振器通过安装有磁流变液均布结构，当地铁经历长时间停运后重新运行时，隔振器工作时通过剪切混合与离心力混合相结合，促使隔振器内的铁磁颗粒与承载液混合均匀，保证隔振器使用时的阻尼力大小，提升隔振器的性能，且避免隔振器因铁齿颗粒与承载液混合不均造成损坏，延长隔振器使用寿命。
