时速120km地铁梯形轨枕轨道现场测试与分析
Test and Analysis of Ladder Sleeper Track for 120km/h Metro
摘要
Abstract
In order to evaluate the damping effect of the ladder sleeper track for 120km/h metro, the damping effect of the ladder sleeper track is analyzed and compared with that of the ordinary long sleeper monolithic track in the time and frequency domain based on the dynamic test of a subway line.The results show that the damping effect of the ladder sleeper track is good and vibration is effectively reduced.The ordinary long sleeper monolithic track can effectively reduce the diffusion of vibration acceleration from rail to track bed, but its damping effect in reducing vibration acceleration from tunnel to track bed is weaker than that of the ladder track.On the whole, the damping effect of is better than that of the ordinary long sleeper monolithic track, and the ladder sleeper track can effectively reduce the middle-high frequency noise.关键词
