Description
For a heavy haul railway vehicle negotiating tight curves in a factory yard, it is beneficial to employ forced steering trucks to reduce the lateral force between the wheel and rail. The forced steering truck has a wheelset supporting mechanism composed of hanging links and compressing ones for easy steering. The truck should also have a short wheelbase to meet special requirements in the yard. This paper deals with numerical analysis of dynamic behavior of the forced steering truck, in which running stability and the lateral force are examined, considering the wheelbase, the running speed, the longitudinal stiffness caused by the link mechanism, steering link stiffness and the leverage ratio. Results show that it is disadvantageous for both the running stability and the curving behavior to use a short wheelbase, and that the decrease of the steering link stiffness and the increase of the running speed also have disadvantageous effects on the curving performance. It is important for trade-off between the running stability and the curving behavior to select proper values for the longitudinal stiffness of the link mechanism and the leverage ratio.
