The existing designs of locomotive support and returning devices are analyzed, their main advantages and disadvantages are determined. A solid-state model of a four-axle locomotive moving along track irregularities is developed. The model is verified with the data of full-scale tests. On the basis of multiple calculations, the rotation resistance parameters in the supports are determined, providing rational dynamic characteristics of the locomotive. An original design of an unattended support-and-returning device is proposed. Its dynamic model is made, integrated later into the model of locomotive movement along real track irregularities. The dynamic characteristics of the locomotive are evaluated using the proposed design of the support-and-returning device. Proposals are made to modernize existing support-and-returning devices in order to obtain higher reliability and durability.
