AN ANALOG-DIGITAL METHOD OF DETERMINING VERTICAL TRACK IRREGULARITIES AS THE EXCITATION OF A RAIL VEHICLE'S VERTICAL OSCILLATIONS

Unknown dynamic parameters of the track have been obtained by statistical calculations. The parameters are used to design an analog-system to determinate a "substitute vertical track irregularity" as an excitation of vertical vehicle oscillations for the accepted model of the track. The signal recorded on the magnetic tape may also be used for an analog study of the vertical vibrations of other vehicles. The computations have been based on the correlation function method.
