INDEPENDENTLY ROTATING WHEELS FOR HIGH SPEED TRAINS

An investigation has been made of the possible application of independently rotating wheel systems to high speed rail systems. The objective of this application is to eliminate the hunting stability problems inherent in conventional wheel systems, and thus improve the vehicle ride comfort and safety. A study of possible wheel-rail configurations indicated that a single point contact with zero contact angle and a difference between wheel and rail contour radii of between 5 and 10 in. was preferable. An individually rotating wheel system appears to be a strong candidate for high speed rail systems.
