Frequency-adjustable steel rail vibration absorption device for restraining corrugation of steel rail and application method of frequency-adjustable steel rail vibration absorption device
The invention relates to the technical field of rail traffic, in particular to a frequency-adjustable steel rail vibration absorption device for restraining steel rail corrugation and an application method thereof.The frequency-adjustable steel rail vibration absorption device comprises a mass block, a connecting rod piece, a damping rubber ring and a steel rail connecting and fixing buckle, the connecting rod piece is installed on the steel rail connecting and fixing buckle, the damping rubber ring is arranged between the connecting rod piece and the steel rail connecting and fixing buckle, the mass blocks are detachably arranged at the two ends of the connecting rod piece in a sleeving mode, and the positions of the mass blocks on the connecting rod piece are adjustable. The method has the advantages that the design purpose of rail corrugation suppression is achieved, namely, the transverse dynamic creep rate between wheel rails is suppressed, the rail attenuation rate in a specific frequency range is increased, corrugation hazards are relieved, meanwhile, the problems of environmental vibration and noise are solved, the rail replacement frequency is reduced, the rail service life is prolonged, and the rail corrugation suppression effect is achieved. And the operation and maintenance cost is greatly reduced.
本发明涉及轨道交通技术领域，尤其是一种抑制钢轨波磨的可调频钢轨吸振装置及其应用方法，包括质量块、连接杆件、阻尼橡胶圈和钢轨连接固定卡扣，其中所述钢轨连接固定卡扣与钢轨的结构形式相吻合适配，所述连接杆件安装在所述钢轨连接固定卡扣上且两者之间设置所述阻尼橡胶圈，所述质量块可拆卸的套装在所述连接杆件的两端且所述质量块在所述连接杆件上的位置可调。本发明的优点是：满足了针对钢轨波磨抑制的设计目的，即抑制轮轨间的横向动态蠕滑率，增大特定频率范围的轨道衰减率，减缓了波磨危害的同时，缓解了环境振动与噪声问题，减少了钢轨更换频率，延长了轨道使用寿命，极大降低了运维成本。
