Modeling and Analysis of Linearized Wheel-Rail Contact Dynamics

Modeling and Analysis of Linearized Wheel-Rail Contact Dynamics

The dynamics of the railway vehicles are nonlinear and depend upon several factors including vehicle speed, normal load and adhesion level. The presence of contaminants on the railway track makes them unpredictable too. Therefore in order to develop an effective control strategy it is important to a...
