Accurate measurement of wheel/rail force is the premise and basis of monitoring the train operation status. This paper analysed the discontinuous and continuous measurement method of instrumented wheelset, studied the variational characteristics of wheel/rail contact state, established the space model of wheel/rail contact force state estimation, proposed the wheel/rail force calculation method based on state estimation. The algorithm was verified by simulation calculation. Moreover, continuous measurement was achieved in actual track test by simple discontinuous wheelset.
