摘要
针对城市轨道交通钢轨扣件及道床减振模拟的在线测试研究设计,讨论其综合试验平台的设计思路、测试项目及主要结构方案。通过计算分析,确定该试验平台总长度、分块长度等关键参数选取的合理性。研究表明,平台建成后可为深入研究城市轨道交通领域应用的各类型轨道减振措施提供试验场所,并提出合理的参数优化建议,为今后减振轨道结构的设计选型提供基础试验数据和理论支持。
The paper introduces the design idea,test items and main structural options for a comprehensive experiment platform to test and study urban rail transit track fasteners and roadbed vibration reduction.The rationality of key parameters such as the total length of the experiment platform,the block lengths,etc.was confirmed through calculations and analyses.The experiment platform will be the place where different kinds of track vibration reduction measures of urban rail transit could be tested.Authors put forward suggestions for choosing optimal parameters so as to provide basic experimental data and theoretical support for the vibration reduction design of track systems.
