Electromagnetic variable-stiffness self-adjusting steel spring floating slab track system and vibration isolator
The invention relates to an electromagnetic variable stiffness self-adjusting steel spring floating slab track system and a vibration isolator, the vibration isolator comprises an outer sleeve and an inner sleeve, the top of the inner sleeve supports the outer sleeve, and a steel spring is arranged between the inner sleeve and the outer sleeve; the inner sleeve is internally divided into an outer cavity and an inner cavity; an upper iron core and an upper coil are arranged at the upper part in the inner cavity, and a lower iron core and a lower coil are arranged at the lower part in the inner cavity; an outer coil is arranged on the inner wall of the inner cavity; an electromagnetic force is controlled to be suction force or repulsive force by adjusting the coil current direction of the upper coil and the lower coil, the suction force or the repulsive force is controlled by adjusting the current, and therefore the rigidity of the vibration isolator is adjusted. When the upper coil and the lower coil have relative displacement, an electromagnetic field changes, and the induction current of the outer coil is detected to obtain vibration displacement. The rigidity of the vibration isolator can be adjusted in real time according to the field excitation main frequency so as to adapt to the actual engineering situation, and therefore broadband vibration reduction and noise reduction are achieved, the rail vibration state is detected in real time, and rail diseases are found as soon as possible.
本发明涉及电磁变刚度自调节钢弹簧浮置板轨道系统及隔振器，所述隔振器包括外套筒和内套筒，内套筒顶部支撑外套筒，内套筒和外套筒之间设置钢弹簧；内套筒内分为外腔室和内腔室；内腔室内上部为上铁芯和上线圈，下部为下铁芯和下线圈，内腔室内壁设置外线圈；通过调节上线圈和下线圈的线圈电流方向控制电磁力为吸力或斥力，通过调节电流的大小控制吸力或斥力的大小，从而调节隔振器的刚度；上线圈和下线圈有相对位移时引起电磁场的变化，检测外线圈感应电流获得振动位移。本发明可以根据现场激励主频，实时调整隔振器刚度，以适应工程实际情况，从而实现宽频带减振降噪，实时检测轨道振动状态，及早发现轨道病害。
