HUNTING STABILITY OF THE THREE AXLE LOCOMOTIVE TRUCK

The hunting stability of the 3-axle locomotive truck is evaluated, using a linear eleven degree of freedom model. Predictions from the model are validated with test data, and the effects of key parameters--wheel profile, primary suspension stiffness, and secondary suspension damping--on hunting stability are shown.
