Abstract

In this paper, to lay a foundation for monitoring wheel-rail contact forces, a non-contact inductor-capacitor (LC) tank composed of a rectangular printed circuit board (PCB) coil and a fixed capacitor is used to sense the variation of micro-properties in a C50 steel specimen caused by the uniaxial tensile force, based on magnetic inductive sensing. The test result shows the resonant frequency of the LC tank has a positive correlation with the loading force. It paves the way for the utilization of LC oscillators on wheel-rail contact force monitoring of high-speed railways.
