ASCERTAINMENT OF THE BEHAVIOUR OF A MOVING RAILWAY VEHICLE BY MEANS OF REDUCED PARAMETERS

The equations of motion of a railway vehicle can be tackled in an efficient way by introducing reduced (dimensionless) quantities (variables and parameters). This is shown for the case of a purely straight track and parasitic displacements which are so small that the system can be linearized. The coefficients of the various terms in the equations turn out to depend on a restricted number of reduced parameters. Further on, the reduction can be carried out in such a way that some of the parameters always are about equal to zero, some others always are about equal to unity, another set of parameters remains anyhow in a restricted interval, whereas the remaining parameters (the reduced velocity and the reduced spring rigidities) in principle can change from zero to infinity. In view of the stability investigation, there was developed a computer program yielding root locus configurations by means of a plotter.
