Nonlinear steel rail damper and steel rail damping system
The invention relates to the field of railway traffic transportation, in particular to a nonlinear steel rail damper and a steel rail damping system, which comprise Euler beams, a vibration absorption mass block, a bracket, a rubber damper and a mounting plate, the two ends of the Euler beam are supported by the support, the middle of the Euler beam is fixed to the vibration absorption mass block, and the vibration absorption mass block is fixed to the rubber damper. And the bracket and the rubber damper are fixed on the mounting plate. Compared with the prior art, the nonlinear steel rail damper and the steel rail damping system have the beneficial effects that the Euler beam is adopted as a nonlinear rigidity output element, the access length and the vibration absorption quality of the beam are adjusted, different vibration suppression frequencies can be adjusted, compared with a common steel rail damper, the nonlinear steel rail damper has a wider vibration suppression frequency band, and the vibration suppression efficiency is improved. And the medium-high frequency vibration phenomenon of the steel rail is effectively improved.
本发明涉及铁路交通运输领域，特别是指一种非线性钢轨阻尼器及钢轨减震系统，包括欧拉梁、吸振质量块、支架、橡胶阻尼器、安装板；所述欧拉梁的两端由所述支架支撑，所述欧拉梁的中部固定于所述吸振质量块上，所述吸振质量块固定于所述橡胶阻尼器上；所述支架与所述橡胶阻尼器均固定于所述安装板上。与现有技术相比较，本发明提出的一种非线性钢轨阻尼器及钢轨减震系统，有益效果在于采用欧拉梁作为非线性刚度输出元件，调节梁的接入长度和吸振质量，可调整不同的抑振频率，相比普通钢轨阻尼器，具有更宽的抑振频带，钢轨的中高频振动现象得到了有效的改善。
