Floating slab track vibration isolator integrating particle damping vibration absorption and band gap vibration resistance
The invention relates to the field of track vibration and noise reduction, in particular to a floating slab track vibration isolator integrating particle damping vibration absorption and band gap vibration resistance. The vibration isolation device comprises a vibration isolation assembly, the vibration isolation assembly comprises a connector of a rotary structure, an inner ring rubber layer, an outer ring rubber layer, a steel vibrator shell and a plurality of damping particles filled in the steel vibrator shell, the connector is provided with a containing groove, the inner ring rubber layer is located in the containing groove, the inner ring rubber layer is connected with an aluminum alloy connector, and the outer ring rubber layer is located in the containing groove. The outer ring rubber layer is coaxially sleeved on the outer peripheral surface of the connector, and the steel vibrator shell is sleeved on the outer peripheral surface of the outer ring rubber layer; the multiple sets of vibration isolation assemblies are arranged in the axial direction, and the two connectors in the adjacent vibration isolation assemblies are connected. The requirements for rigidity and low-frequency band gaps can be met, and resonance peak surge is avoided when vibration and noise reduction are conducted on the track.
本发明涉及轨道减振降噪领域，具体为一种颗粒阻尼吸振和带隙阻振相融合的浮置板轨道隔振器。其包括隔振组件，隔振组件包括回转形结构的连接器、内环橡胶层、外环橡胶层和钢振子外壳以及填充在钢振子外壳内的多个阻尼颗粒，连接器具有容纳槽，内环橡胶层位于容纳槽内，且内环橡胶层与铝合金连接器连接，外环橡胶层同轴套设在连接器外周面上，钢振子外壳套设在外环橡胶层外周面上；隔振组件沿轴向设置有多组，相邻隔振组件中的两个连接器连接。本发明能满足刚度和低频带隙要求，且在对轨道进行减振降噪时避免共振峰激增。
