EFFECT OF DRY FRICTION IN LINK SUSPENSION ON FORCED VIBRATION OF TWO-AXLE CAR

The frictional force of leaf bearing springs and double links make great influence to the running stability of a two-axle railway car. The forced vibration of a two-axle car is analyzed using half body model and obtained following results. Motion of a car body takes three different patterns with the change in frictional force of link suspension. Limit frictional forces between these three motions are obtained. A criterion function to evaluate the running stability is introduced and the lower limit of optimum friction coefficient of link suspension and bearing spring are 0.06 - 0.08 and 0.11 respectively with this criterion function.
