Railway fastener with adjustable rigidity and damping
The invention discloses a railway fastener with adjustable rigidity and damping, which comprises a fastener body, and a through hole is formed in the middle of the fastener body; a composite steel base plate and a magneto-rheological elastomer base plate are sequentially arranged in the through hole from top to bottom, and a packaging magnetic control element preset in the sleeper is arranged below the magneto-rheological elastomer base plate. According to the railway fastener, the elastic property of a fastener system can be regionally and individually adjusted according to line operation conditions, and the effects of attenuating impact load, controlling vibration of a track structure and reducing structural noise of the fastener are achieved.
本发明公开了一种刚度阻尼可调的铁路扣件，该铁路扣件包括：扣件本体，扣件本体的中部设置有通孔；通孔内自上而下依次设置有复合钢垫板和磁流变弹性体垫板，磁流变弹性体垫板的下方设置有预设在轨枕中的封装磁控元件。该铁路扣件可根据线路运营条件，区域化和个性化的调整扣件系统弹性属性，实现扣件具备的衰减冲击荷载、控制轨道结构振动以及降低结构噪声的作用。
