The response of the A.P.T.E. mechanical transmission to discrete track irregularities (IM-PS-031)

This memorandum is concerned with the dynamic effects experienced by the A.P.T.E. mechanical transmission when a powered wheelset meets a rail joint. A diagram of the transmission, based on SK/APT/490D, is shown in figure 1. The source of the dynamic forces which will occur in the system is the...
