Rezumat:

This paper describes a computer aided approach to the study of the longitudinal dynamics of a
braked train. The numerical simulation of the phenomena takes into account the delay between the braking
action of the cars and the fact that the values of the braking force of each wagon is reached gradually, in
certain time after the braking command. The values of the time interval elapsed between the braking command
and the moment when the nominal braking force is reached are given by international railway regulations. The
time variation of the braking force in this interval is determined both with the aid of a computerized
experimental stand and through mathematical functions and its influence is analyzed in the present study.
