Abstract

Determining the vertical wheel-rail force by measuring rail displacement is approved to be feasible in this paper. Wheel-rail force data is collected following the common way firstly, i.e. strain gauge is pasted on the rail to measure the strain. During the test, different vehicle running speeds through the measuring point are considered. In the same time, rail displacement data is measured by the laser ranging technology. The measured rail displacement data are used in the finite element analyzing process in order to calculate the corresponding vertical wheel-rail force. The wheel-rail force is calculated based on Winkler Beam theory. Calculated vertical wheel-rail force through FEA by using the tested rail displacement and the measured vertical wheel-rail force are subsequently compared. Calculated vertical wheel-rail force by using the measured rail displacement can meet the tested vertical wheel-rail force via strain gauge rather well, indicating that the measuring method of vertical wheel-rail force proposed in the current paper is reasonable. It can meet the accuracy requirements of the practical engineering from both analytical and numerical perspective.
