    Abstract: A damper for reducing the track nose emitted by a rail system comprises a deformable material attachable to a surface of the rail, incorporating a plurality of elongate discontinuous resonant members of a stiff material as compared to the deformable material, sized to contain at least two resonant frequencies in the range of interest. The resonant members are suitably of steel or other metallic material. They can be of different profile, to form a resonant system with at least two resonant frequencies in the relevant frequency range. They are suitably embedded in the deformable material, to ensure adequate vibrational transfer from the rail to the resonant members and also provide environmental protection. The deformable member is visco-elastic, for example rubber or rubber-like material. This may be preformed and glued to the rail, or it can be cured in place on the rail. The damper is positioned on the rail at the junction between the web and the foot of the rail. One resonant member can be an elongate angled section, the angle preferably matching the angle between external surfaces of the head and foot. Another resonant member can be a solid elongate block, the external faces adjacent the web and foot being angled to match.

    Abstract translation: 用于减小由轨道系统发射的轨道鼻部的阻尼器包括可变形材料，其可附接到轨道的表面，与可变形材料相比，结合有多个细长的不连续的刚性材料的不连续共振构件，其大小适于容纳至少两个共振 频率在感兴趣的范围内。 共振构件适合于钢或其它金属材料。 它们可以具有不同的轮廓，以形成在相关频率范围内具有至少两个谐振频率的谐振系统。 它们适当地嵌入在可变形材料中，以确保从轨道到共振构件的足够的振动传递并且还提供环境保护。 可变形构件是粘弹性的，例如橡胶或橡胶状材料。 这可以预先形成并粘合到轨道上，或者可以将其固化在轨道上的适当位置。 阻尼器位于轨道和轨道脚之间的连接处。 一个共振构件可以是细长的成角度的部分，该角度优选地与头部和脚部的外表面之间的角度相匹配。 另一个共振构件可以是实心的细长块，邻近腹板和脚的外表面成角度匹配。
