摘要
利用车辆-轨道耦合动力学理论所编制的程序,计算弹性轨枕有碴轨道与普通轨枕有碴轨道在相同工况下的动力响应。通过对两种轨道动力响应的对比分析,表明弹性轨枕不仅能够提高轨道弹性,缓和列车冲击,减轻道床振动,减少道碴粉化,延长轨道维护周期,还能保持行车的安全性与平稳性。
By running the program based on vehicle-rail coupling dynamics, compute the dynamic response of elastic sleeper ballasted rail and common sleeper ballasted rail under same working condition. The analysis reveals elastic sleeper may better springiness of rail, cushion the shock on the train, and the vibration of ballast bed, lessen smash of ballast, prolong track maintenance circle, also keep train on a safe and quiet run.
