Research of System Vehicle-track when Wheel is Scaled

The interaction between wheel and rail is still a great problem of railway engineering. A mathematical model of the system Vehicle-Track, previously developed by the same authors and a newly developed model of vehicle wheel that is scaled, are used to create a new mathematical model. This model allows to determine changes of dynamical characteristics in rails and to evaluate physical and mechanical properties of the system Vehicle-Track. Results, obtained when rail is in contact with vehicle scaled wheel are compared with results obtained when the wheel is without scales.
