Modeling and Control for Rail Vehicle with Comfort Evaluation

Author: Mortadha Graa

Abstract: Investigation of control vibration is an important topic for the purposes of ride comfort in railway engineering. The vibration of rail vehicles becomes very complex because it is affected by the condition of vehicles, including suspensions and wheel profile, condition of track sections, including rail profile, rail irregularities, cant and curvature. The present study deals with the modeling and control for vertical active suspension rail vehicle by PID-ZN controller. A model of 17 degrees of freedom is adopted which consists of one car body 2 bogies and 4 wheel-sets. A Sperling ride index (ISO2631) is calculated using filtered RMS accelerations in order to evaluate the ride comfort. It should be noticed that the control model was carried out to improve Wz index about 41% at speed of 60 m/s.
