After developing the theory of self-excited nosing of 2-axle freight car whose car body is elastically suspended, that is, longitudinally and transversely movable in relation to the axles, the author discusses the general properties involved with the critical nosing speed and the methods of prevention. The theory deals with the stability problem of linear vibration in small displacement. There are two different methods of preventing the nosing of 2-axle cars, namely (a) a method in which the lower stable region is used by making the lateral stiffness of axle sufficiently large, and (b) a method in which the upper stable region is used by making the lateral stiffness of axle as small as possible. It is pointed out that the latter method is recommendable especially for 2-axle freight cars.
