Abstract

The influence of the shock processes on railway vehicles with one-stage spring suspension is analyzed in this paper. These processes are excited in normal operation. Kinetic energy is lost as a result of the shock loads. Expressions are derived to calculate the kinetic energy of the different units and of the railway vehicle as a whole. These expressions allow calculating the loss of the kinetic energy of the mechanical system. Another objective of this work is to solve optimization tasks. This optimization allows the parameters of the railway vehicle to be chosen so that the loss of kinetic energy to be minimal and the effective work of the transport vehicle to be guaranteed in normal operation.
