在城市轨道交通建设轨道设计过程中,由于现场客观需要,经常需要局部增大轨枕间距。车辆—轨道动力学理论计算结果表明,轨枕间距局部增大后,刚度不平顺对车辆、轨道系统的动力冲击作用是客观存在的,但是这种冲击作用相对较小,对车辆、轨道系统的动力学影响不是控制轨枕间距局部增大量的因素。
During the design of urban rail transit orbit design, due to the objective needs of the scene, it is often necessary to increase the sleeper spacing locally. The theoretical calculation of vehicle-orbit dynamics shows that the dynamic impact of the unevenness of the sleeper on the vehicle and the track system is objective after the local increase of the sleeper spacing, but the impact is relatively small. Therefore, the dynamic of the vehicle and the track system Learning influence is not a factor that controls the local increase in sleeper spacing.
