With the laws governing the statics of a bogie in a curved track as the starting point, the system of interdependent differential equations describing the impact process for a four-axle bogie vehicle running into a non-superelevated rail curve (points) at constant speed was drawn-up and solved on an analogue computer. The following quantities were varied:
angle of impact;
guide spring rate;
lateral stiffness of coupling between bogies and vehicle body (length of cradle pendulums);
damping constant of cradle dampers.
The results of the calculation are illustrated with reference to practical measures with the aid of figures.
