Vibration isolator, floating slab track and control method of floating slab track
The invention discloses a vibration isolator, a floating slab track and a control method of the floating slab track. The vibration isolator comprises a stator, a rotor, a spring and a magnet exciting coil, the stator is cylindrical, and a plurality of first magnetic grooves are formed in the inner wall of the stator; the rotor is installed in the stator, and a plurality of second magnetic grooves matched with the first magnetic grooves are formed in the rotor. The springs are arranged at two ends of the rotor; the excitation coil is arranged on the rotor in a sleeving mode so as to apply load to the rotor when powered on. The floating slab track comprises the vibration isolator. Due to the fact that the magnet exciting coil is arranged on the rotor in a sleeved mode, in the application process, if the rotor moves, the positions of the second magnetic grooves and the first magnetic grooves are dislocated, the magnet exciting coil can exert loads opposite to the dislocated direction on the rotor, and therefore movement of the rotor is slowed down. Therefore, the rigidity of the vibration isolator is adjusted by changing the current intensity of the magnet exciting coil, then the inherent characteristics of a spring-mass system of the floating slab track are flexibly adjusted, and the stability of the vibration reduction performance of the floating slab track is improved.
本发明公开了一种隔振器、浮置板轨道及浮置板轨道的控制方法。隔振器包括定子、动子、弹簧和励磁线圈，定子呈筒状，定子的内壁上形成有多个第一磁槽；动子安装于定子内，且动子上形成有多个与第一磁槽配合的第二磁槽；弹簧设置于动子的两端；励磁线圈套设在动子上，以在通电时对动子施加荷载。浮置板轨道包括上述的隔振器。由于在动子上套设了励磁线圈，在应用时，若动子移动，导致第二磁槽与第一磁槽的位置发生错位，励磁线圈就会给动子施加与错位方向相反的荷载，以减缓动子的移动。因此通过改变励磁线圈的电流强度实现了对隔振器刚度的调节，进而实现对浮置板轨道弹簧‑质量系统固有特性的灵活调节，提升浮置板轨道减振性能的稳定性。
