摘要
提出基于光纤布喇格光栅(FBG)传感技术监测轮轨垂向力的方法。根据FBG传感特性和轮轨作用力的特点,给出FBG轮轨垂向力监测原理,并设计出可以实现分布式传感监测的监测系统结构。最后通过有限元仿真计算验证提出的轮轨垂向力监测方法的正确性。
The paper proposes a method which can monitor of wheel-rail vertical force based on the fiber Bragg grating （FBG） sensing technology. According to the characteristics of the FBG sensing and the wheel-rail forces, the paper develops the principle of wheel rail vertical force monitoring based on FBG, de-signs the structure of monitoring system which realize distributed monitoring, finally, the paper verifies the correctness of the wheel-rail vertical force monitoring method by the finite element simulation.
