Guidance and Stability of Articulated Railway Vehicles with Single Axles and Various Forms of Passive and Active Steering

摘要

The dynamics of vehicles with articulated car bodies is discussed. Configurations with conventional wheelsets and either forced steering (steering derived from relative motions between car bodies) or self steering (steering derived from wheelset motions only) are compared with vehicles with active steering based on lateral displacement feedback. It is shown that for passive steering there are significant advantages in self steering where interaction between wheelsets and body is minimised.
