Vibration reduction fastener system and rigidity adjusting method thereof
A vibration reduction fastener system comprises a sleeper and a vibration reduction fastener which is arranged on the sleeper and used for buckling and pressing a steel rail, and is characterized in that the vibration reduction fastener is in elastic contact with the sleeper, and the contact area of the vibration reduction fastener and the sleeper is increased along with the increase of the load of the steel rail, so that the vertical rigidity of the vibration reduction fastener is in nonlinear change in the bearing process. Small load and small deformation are formed, high vibration reduction is achieved, large load and large deformation prevent the steel rail from tipping over, the overload protection function on the steel rail is achieved, steel rail deformation is restrained within a certain range, the safety of a rail line is guaranteed, the transverse rigidity of the vibration reduction fastener is increased when a vehicle turns, the vibration reduction performance of the vibration reduction fastener is further improved, and the service life of the vibration reduction fastener is prolonged. Deformation of the steel rail is reduced, and the rigidity requirements of the vibration reduction fasteners on the rails under different road conditions and the rigidity change requirements of the vibration reduction fasteners on the rails under complex road conditions are met. The invention further provides a rigidity adjusting method of the damping fastener system.
减振扣件系统，包括轨枕和装在轨枕上用于扣压钢轨的减振扣件，其特征在于：所述的减振扣件与轨枕为弹性接触且随钢轨载荷的增加而增大与轨枕的接触面积，使承载过程中减振扣件的垂向刚度呈非线性变化。本发明形成小载荷小变形实现高减振，大载荷大变形防止钢轨倾翻，形成对钢轨的过载保护功能，将钢轨变形抑制在一定范围之内，保证轨道线路的安全性，增大减振扣件在车辆拐弯时的横向刚度，进一步提高减振扣件的减振性能，减少钢轨的变形，满足不同路况轨道上减振扣件的刚度需求以及复杂路况轨道上减振扣件的刚度变化需求。本发明还提供一种减振扣件系统的刚度调节方法。
