Composite floating slab track vibration isolator
The invention discloses a composite floating slab track vibration isolator which comprises a first part and a second part. The first part is composed of an upper cover plate, a spring, a damper, a mass block and an outer sleeve, and the second part is composed of an adjusting base plate, a rubber metal spring, an inner sleeve, a limiting mandrel and a base plate. When a train passes by, the spring, the damper and the mass block of the first part form a tuned mass damper, low-frequency vibration is controlled, and the adverse effect of vibration amplification of the floating slab structure nearthe inherent frequency is restrained; the second part adopts a rubber metal spring, so that the effects of effectively reducing vibration and supporting the floating slab ballast bed are achieved; the vibration absorber is simple in structure, the tuned mass damper is arranged in the closed cavity and is convenient to install and replace, the problems that an existing floating slab track is insufficient in low-frequency control and a vibration isolation element is difficult to replace are solved, and the economical efficiency and the vibration absorption effect are good.
本发明公开了一种复合型浮置板轨道隔振器，它包括上盖板、弹簧、阻尼器、质量块和外套筒构成的第一部分与调节垫板、橡胶金属弹簧、内套筒、限位芯轴和底座板构成的第二部分；在列车经过时，第一部分的弹簧、阻尼器和质量块构成调谐质量阻尼器，控制低频振动，抑制浮置板结构在固有频率附近振动放大的不利影响；第二部分采用橡胶金属弹簧，起到有效减振和支撑浮置板道床的作用；该减振器结构简单，调谐质量阻尼器置于密闭腔室中，安装、更换方便，解决了现有浮置板轨道对低频控制不足、隔振元件更换困难的问题，经济性好，减振效果好。
