摘要
列车定位天线是轨道交通信号系统的关键设备之一,其长期可靠稳定运行是信号系统能实时追踪列车运行的前提。通过阐述和分析当前定位天线的安装方式与实际振动情况,同时结合地铁行业标准振动测试的要求,创新采用了钢丝绳减振器来重新设计定位天线的安装,详细计算了减振效率,并对冲击进行了安全校核。
The train positioning antenna is one of key equipment of the signal system in rail tran-sit,its long-term reliable and stable operation is the premise for enabling the signal system to track train operation in a real time manner.Through analyzing the current installation mode and actual vibration of the positioning antenna,a steel cord shock absorber is used to redesign the in-stallation of the positioning antenna in compliance with the requirements of the vibration test standard for subway industry.The damping efficiency of the absorber was calculated in detail and safety check of shock was also conducted.
