摘　　要：为准确获得第三轨受流器的动态接触力,以武汉地铁某线列车使用的第三轨受流器结构为研究对象,采用有限元法确定了应变片的布置位置,建立了靴轨动态接触力与应变值/加速度值的理论关系式,通过静、动态标定试验获得关系式中的等效参数,并通过对比分析验证了模型和等效参数的精确性。In order to accurately obtain the dynamic contact force of the third rail receiver,the structure of a third rail receiver used by a metro train in Wuhan City is studied.Then,the installing position of strain gauges is determined through finite element analysis,the theoretical formula between the dynamic contact force of boot/rail and the strain/acceleration value is established.The equivalent parameters of which are obtained through static and dynamic calibration experiment,the accuracy of the calculation model and the equivalent parameters are verified according to a comparative analysis.
