Abstract

Wheel set flange derailment criteria for railway vehicles are derived and the influence of wheel-rail contact parameters is studied. An indirect method for wheel-rail force measurement based on these derailment evaluation criteria is proposed. Laboratory tests for the calibration of strain-force devices on the bearing box are carried out to determine the relationship between the applied force and the measured strain. The simulation package, SIMPACK, is used to develop a passenger car model to generate wheel-rail forces and vibration signals. Different cases are considered in this model to provide an accurate validation of the identified wheel-rail forces. A feasibility test is conducted in the Beijing Loop test line using a passenger car equipped with a set of strain gauges on the wheel set. The comparison of the force time history applied to the instrumented wheel set and that obtained using the indirect method is presented.
