Abstract


Controlling analysis for lateral and yaw motion has great influence on rail wheelset model during running. To avoid slip due to lower adhesion, sliding due to higher speeds and balance of creep forces is attributed by degree of freedom (DOF). Here simple dynamics of lateral and yaw motions in terms of displacement, velocity and acceleration has been discussed. This correlation depending upon creep co-efficient is shaped into matrix form too. In this paper an effort has been consumed to observe the correlation and behavior of the lateral and yaw motion analysis based upon its geometry. The railway wheelset is modeled depending upon preliminary values of parameters. The step response of lateral and yaw motion has been performed to study attitude of each other based upon time variant.
