Rigid-flexible coupling type turnout damping fastener system
A rigid-flexible coupling type turnout damping fastener system comprises an iron base plate, an under-plate elastic cushion layer, a heightening base plate, an elastic rail brace, eccentric bushings and an under-rail elastic base plate, the eccentric bushings are inserted into oblong holes in the two ends of the iron base plate and the two ends of the under-plate elastic cushion layer, and turnout tie bolts penetrate through the eccentric bushings and then are fixed to a turnout tie; the under-plate elastic cushion layer is formed by compounding low-rigidity and high-rigidity materials, the elastic rail brace is in elastic contact with a steel rail, the track gauge is adjusted by rotating the eccentric sleeve by 180 degrees, and the transverse rigidity of the fastener system is increased through the elastic rail brace; the fastener system has small vertical rigidity and large transverse rigidity, it can be ensured that the fastener system can provide enough vibration reduction elasticity for the steel rail in the vertical direction, meanwhile, the vertical displacement can be controlled within the design range, and therefore the stability of the steel rail and the running smoothness of a train are improved; and on the other hand, the mutually assembled parts of the fastener system are designed according to the rigid-flexible coupling contact relation of metal and nonmetal, so that the impact vibration of a train on the steel rail can be buffered.
一种刚柔耦合型道岔减振扣件系统，包括铁垫板、板下弹性垫层、调高垫板、弹性轨撑、偏心套及轨下弹性垫板，所述偏心套插装在铁垫板、板下弹性垫层两端的长圆孔中，通过岔枕螺栓穿过偏心套后与岔枕固定，所述板下弹性垫层由低刚度和高刚度材料复合而成，所述弹性轨撑与钢轨弹性接触，通过偏心套旋转180°调整轨距，通过弹性轨撑增大扣件系统横向刚度；本发明具有较小的垂向刚度、较大的横向刚度，可确保扣件系统在为钢轨垂向提供足够减振弹性的同时，能够将垂向位移控制在设计范围内，以提高钢轨的稳定性和列车运行的平顺性；另一方面，扣件系统相互装配的零件按金属与非金属的刚柔耦合接触关系设计，有利于缓冲列车对钢轨的冲击振动。
