Simulation of Hunting of Rail Vehicles : 1st Report : Dynamic Models with Clearances in Various Parts and Transient Phenomena

抄録

Much valuable research has been done on the phenomenon of hunting. However very little research make full allowance for nonlinear factors such as the clearances in wheelset suspension and in truck yaw restraining elements. (1) We have set up dynamic models of four axle vehicles with two-axle bogies that make allowance for the above mentioned clearances and some other nonlinear elements. (2) Simulation for some numerical examples was made by varying values of wheel-rail adhesion coefficient and values of above mentioned clearances. Simulation results coincided with actual tendencies, thus verifying the effectiveness of simulation based on this type of model.
