Method Verification for Wheel-Rail Contact Force Continuous Testing by Using Reduced Scale Model

Wheel and rail defects will produce high impact on railway track structure which will reduce the service life of track components. These defects can be identified easily by wheel-rail contact force continuous testing. In this paper, a reduced scale model of wheel-track system was made to simulate the interaction between wheel and rail. Light rails and woods bar were used to make track and a small car with four wheels was used to simulate a bogie. The strain gages were installed on the rail web according to the testing method developed by authors previously. A series of tests was conducted in laboratory and the results show a high consistency between test results and numerical analysis. A signal processing method was developed to acquire continuous wheel-rail contact force from testing results.
