采用通用的结构动力学分析软件ANSYS仿真分析了双层离散轨道模型在列车荷载作用下的振动响应情况,对无轨道不平顺和有轨道不平顺两种工况进行了有限元计算,分析表明轨道不平顺对轨道结构振动和整体道床作用反力的影响很明显,轨道不平顺越高,轨枕的振动速度加剧,整体道床作用反力峰值也显著增加。 The common dynamic analysis software ANSYS was used to simulate the vibration response of the double-layer discrete track model under the train load. The two cases with no track irregularity and track irregularity were analyzed by FEM. The analysis shows that the orbit The effect of unevenness on the vibration of track structure and the reaction force of the whole track bed is obvious. The higher the track irregularity is, the more the vibration speed of the sleeper is increased and the peak of the reaction force of the whole track bed also increases significantly.
