NEW WHEELSET DESIGN FOR RAIL TRANSPORT.

Economic efficiency and competitiveness of rail transport depends mainly on the reducing the level of the dynamic interaction between wheel and rail. This paper presents a new technical solution for the wheelset in the form of a block design of the wheels. Analysis of the motion path of contact points was carried out in the system «wheelset - rail track». The paper evaluates the stress state of the block construction elements of the wheelset and shows the results of comparative theoretical and prototype tests of the block and standard wheelsets.
