摘　　要：为了研究梯形轨枕轨道在地铁列车以60 km/h速度运行时的振动特性,建立了梯形轨枕轨道的三维有限元振动模型。分析了梯形轨枕轨道在轮轨粗糙度激励下的振动响应特性。通过与普通地铁轨道进行对比,可知梯形轨枕轨道具有良好的减震能力。In order to study the vibration characteristics of the trapezoidal sleeper track when the subway train is operated at 60 km/h speed, a three-dimensional finite element vibration model of the trapezoidal sleeper track is established. The vibration response characteristics of the trapezoidal sleeper track under the wheel rail roughness excitation are analyzed. By comparing with ordinary subway tracks, it can be seen that the trapezoidal sleeper track has good vibration damping capability.
