Abstract
Non-linear equations of turnability of a two-axle wheeled vehicle and an equation equivalent to the Pevzner equation for defining the whole set of stationary conditions of its model are derived. The advantages of the presented approach lie in removing the inaccuracies of geometry exploited by Ya.M. Pevzner. It also enables analytical and numerical analysis of the whole set of stationary conditions of the vehicle model provided that non-linear dependence has its inverse function that defines the skid force as a function of the skid angle. The paper presents original results that define the analytical conditions for divergent loss of stability of a two-axle wheeled vehicle in a circular curve, with the Ackermann angle being invariable. An illustration is given of this case of vehicle stability loss within a context of a more general picture of divergent loss of stability of the whole set of stationary conditions of the model.
