Research of dynamic forces occurring in the contact between the railway rail and damaged wheel
Abstract
System “Vehicle-Track” is examined, in which alteration of contact forces, depending on wheel damages and their sizes, is researched. A mathematical model of the system “Vehicle-Track” has been developed, in which dynamical characteristics of railway vehicle, rail, sleeper and railway roadbed are evaluated. Mathematical model of the system “Vehicle-Track” consists of non-linear differential equations. Alterations of forces occurring, moments and other parameters in the system „Vehicle-Track“ are assessed, depending on the size of damages, rolling velocity and static load.
