Model Based Indirect Conicity Estimation Technique for Solid Axle Railway Wheelset

Conicity is an important characteristic that helps the railway vehicle to steer itself down track. However during operation, conicity tends change inconsistently due frictional contact at wheel-rail interface. Safety, reliability and ride comfort which are utmost importance for journey adversely affected changes in level beyond certain limit. Several techniques have been employed monitoring health of wheelset however still a significant potential exists investigate conicity. This paper presents model based technique monitor condition contributes wheel flats decrease problem false flanges increased In this unconstrained solid axle considered study. The dynamic behavior analyzed different levels understand effect on wheelset. order demonstrate research work simulation developed Matlab/ Simulink mimic actual Simplified linearized used estimate dynamics From results it evident frequency vibration changing with level. way using proposed method indirectly identified. produced by satisfactory.
