Broadband energy consumption type track fastener
The invention relates to a broadband energy consumption type rail fastener which comprises an under-rail composite sandwich plate spring assembly and a steel rail elastic restraining assembly, the under-rail composite sandwich plate spring assembly and the steel rail elastic restraining assembly are both fixed to a sleeper, and the under-rail composite sandwich plate spring assembly is located below a steel rail. The steel rail elastic constraint assembly is used for providing steel rail elastic constraint. The under-rail composite sandwich plate spring assembly is composed of a steel rail support, a viscoelastic layer, a damping alloy layer, a plate spring support, a first anchor bolt and a positioning hoop. The plate spring support is fixed to a sleeper through the first anchor bolt. The steel rail support, the viscoelastic layer, the damping alloy layer and the plate spring support are restrained by the positioning clamps, so that large relative slippage is not generated, and eccentric failure of the overall structure of the under-rail composite sandwich plate spring assembly is avoided. The bearing capacity and the effective stroke can be changed by changing the thickness, the width or the number of layers of the viscoelastic layer and the damping alloy layer and the material of the damping alloy layer, and good applicability to both heavy-load and light-load railways is achieved.
本发明涉及一种宽频耗能型轨道扣件，该扣件包括轨下复合夹层板簧组件和钢轨弹性约束组件，轨下复合夹层板簧组件和钢轨弹性约束组件均固定在轨枕上，轨下复合夹层板簧组件位于钢轨下方，钢轨弹性约束组件用于提供钢轨弹性约束。轨下复合夹层板簧组件由钢轨支座、黏弹性层、阻尼合金层、板簧支座、第一锚固螺栓和定位卡箍组成，板簧支座通过第一锚固螺栓固定于轨枕上；钢轨支座、黏弹性层、阻尼合金层、板簧支座由定位卡箍约束从而不产生大的相对滑移导致轨下复合夹层板簧组件整体结构偏心失效。本发明可以通过改变黏弹性层和阻尼合金层的厚度、宽度或层数以及阻尼合金层的材料来改变承载能力和有效行程，对于重载和轻载铁路都具有很好的适用性。
