    <subfield code="a">&lt;p&gt;One of the most sensible issues in the railway industry is the impact on infrastructure of train&lt;br&gt;
operations and the damage on vehicles provoked by the track conditions. These issues have a&lt;br&gt;
significant impact on the life cycle costs of the railway networks. The study of vehicle-track&lt;br&gt;
interaction is important in reducing the operation and maintenance costs, by increasing the life&lt;br&gt;
cycle of both vehicles and tracks, and increasing the speed, safety and comfort indexes of the&lt;br&gt;
railway systems.&lt;br&gt;
This thesis focused on the analysis of effects of radius of curved rail on rail wear. Multi-Body&lt;br&gt;
simulation software SIMPACK is employed to create a one car railway vehicle model with two&lt;br&gt;
bogies with an axle load of 10 ton. The rail material which is applied on the study is UIC 60&lt;br&gt;
standard carbon steel. To verify the simulation results, the SIMPACK model is run on varies&lt;br&gt;
track radius (sharp curves) range from 100 m to 800 m under dry condition. Parameters like track&lt;br&gt;
radius, wheel rail contact patch area, contact pressure, vehicle speed, wheelset yaw angle are&lt;br&gt;
investigated to analyse there effects on rail wear&lt;/p&gt;</subfield>
