In this work, the measurement of instrumented wheelsets is analysed using advanced dynamic models that consider both the wheelset flexibility and the inertial effects associated with its rotation. The results show discrepancies between the simulated response of the instrumentation for the static case and that obtained through the dynamic model. These discrepancies become more pronounced as the vehicle speed and/or the frequency of the force in the wheel-rail contact increase. The more advanced model predicts that resonance frequencies depend on the angular velocity. This effect makes it challenging to develop instrumented wheelsets capable of measuring beyond the natural frequency of the first bending mode.
