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。 The dynamic response of ballast track with elastic sleepers and ballasted track of normal sleepers under the same conditions is calculated by using the program compiled by the theory of vehicle-track coupling dynamics. Comparing the dynamic responses of the two kinds of orbits, it shows that the elastic sleeper can not only improve the elasticity of the track, mitigate the impact of the train, reduce the vibration of the ballast, reduce the powdering of ballast, prolong the maintenance period of the track, but also keep the safety and stability of driving.
