一种新型支撑形式对钢弹簧浮置板轨道振动特性的影响
Research on Effects of a New Supporting Form on Vibration Characteristics of Steel Spring Floating Slab Track
摘要
Abstract
A new supporting form for the steel spring floating slab track is proposed in this paper based on present supporting forms. The effects of this supporting form on vibration characteristics of the steel spring floating slab track are analyzed with numerical model analysis method. The results show that: ( 1 ) The steel spring floating slab track supported by the new form style has lower 1 st order natural frequency than that of the present steel spring floating slab track with same lab length without changing high order natural frequencies and vibration mode. (2)Natural frequencies of first three orders are less affected by the slab length, and the high order ( bending) vibration mode of the steel spring floating slab track is enriched. Therefore, the supporting form proposed in this paper helps improve the ability to reduce vibration of the steel spring floating slab track.关键词
