摘　　要：针对道岔尖轨密贴和开程的动态位移检测问题,采用具有磁致伸缩效应的位移测量技术,在道岔牵引点的定/反位分别安装位移传感器进行尖轨位移的全程动态测量,并对测量数据进行校准、保存、分析和显示。经现场试验验证:该动态检测方法能够满足道岔尖轨位移动态检测功能和性能的要求,为道岔的日常运用维护提供了有力的技术保障手段。In view of the dynamic displacement detection problem of closure and open range for turnout switch rail,the displacement measurement technology with magnetostrictive effect is adopted.The displacement sensors are installed at the fixed/reverse positions of the traction points of the switch for the full dynamic measurement of switch rail displacement,and the measurement data is calibrated,saved,analyzed,and displayed.Through on-site experiments,it's verified that this dynamic detection method can satisfy the requirements for the dynamic detection function and performance of switch rail displacement,providing a powerful technical guarantee for normal operation and maintenance of railway switches.
