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