Floating plate rail capable of achieving wide-frequency damping
The invention relates to a floating plate rail capable of achieving wide-frequency damping, comprising a road bed, a rail plate, a steel, a buckle, a damping cushion and an inertial capacity damping assembly, wherein the rail plate is arranged on the road bed; the steel rail is connected to the rail plate; the steel rail is buckled to the rail plate through the buckle; the damping cushion is arranged between the road bed and the rail plate; the inertial capacity damping assembly is arranged in the rail plate for isolating vibration; the inertial capacity damping assembly comprises an inerter,an elastic part and a damper; the elastic part is arranged in the damper; and the inerter and the damper are connected in series or in parallel. According to the floating plate rail capable of achieving wide-frequency damping disclosed by the invention, the inerter and the damper are connected in series or in parallel to define a mass-spring-inerter-damping system, thus improving vibration isolating and damping performance, at low frequency, of the floating plate rail capable of achieving wide-frequency damping.
本发明涉及一种宽频减振浮置板轨道，包括：道床；轨道板，设于所述道床；钢轨，连接于所述轨道板；扣件，将所述钢轨扣紧于所述轨道板；减振垫，设于所述道床及所述轨道板之间；以及惯容减振组件，设于所述轨道板内以用于隔振；其中，所述惯容减振组件包括惯容器、弹性件及阻尼器，所述弹性件设于所述阻尼器内，所述惯容器与所述阻尼器串联或并联。上述宽频减振浮置板轨道，通过将惯容器与阻尼器串联或并联，以形成质量‑弹簧‑惯容‑阻尼减振系统，从而改善上述宽频减振浮置板轨道在低频的减隔振性能。
