摘要
岔枕是道岔系统的重要组成部分。将岔枕作为弹性地基梁 ,利用车辆 -道岔系统空间耦合振动模型 [1 ] ,模拟计算了车辆过岔时岔枕各相关截面的受力情况 ,以及岔枕振动加速度和弹性变形等振动特性。
Switch sleepers are important part of turnout systems. In this paper, the switch sleepers treated as a Bernoulli Euler beam. Based on a spatial vehicle/turnout coupled vibration model, the forces acting on the switch sleeper are calculated, the response of the switch sleeper, such as the acceleration and the elastic bending, is simulated, and the influence of the velocity of the vehicles on the switch sleeper vibration is analyzed.
