摘要

钢轨状态监测对列车的安全运营具有重要意义。基于光纤光栅传感技术

采用钢轨三维梁模型对轴向应变、竖向和横向曲率进行测量。与传统一维测量模型相比

该方法可以同时测量钢轨竖、横向曲率和轴向力。通过实验室静态轴向加载试验对比了一维和三维模型

验证了三维模型的有效性与优势。

Abstract

Rail stress status monitoring is of great importance for operation safety of train. A three-dimensional beam model for rail based on fiber Bragg grating sensing technology is used to measure axial strain

vertical and transverse curvature of rail. Compared with traditional 1D measurement model

experimental results of both conventional one-dimensional and three-dimensional models indicate that the three-dimensional one can measure both the axial strain and the vertical / transverse curvature.
