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。文章最后分析了过岔速度对岔枕振动特性的影响情况
Turnout is an important part of the turnout system. Using the bolster as the elastic foundation beam, the vibration of the turnout system is simulated by using the space-coupled vibration model of the vehicle-turnout system [1]. The vibration characteristics of the bolster at the relevant section of the switch and the vibration acceleration and elastic deformation of the bolster are simulated. Finally, the article analyzes the influence of the speed of turnout on the vibration characteristics of switch sleepers
