Method for evaluating the performance of antiskid devices
Published 2017-10-01“…From the existing methods of testing antiskid devices, this approach is different in that the performance of an antiskid device is evaluated not on a specific segment of the track with reduced cohesion, but on the estimated track with the worst coefficient of adhesion at each point (the shorter the track section, the faster the wheelset enters the skid, but it is also more difficult to damage it). …”
