Abstract

According to the requirement of raising speed freight train, the dynamic behavior of a modified Zhuan 8A freight car bogie, which is proposed by the Qiqihaer Railway Rolling Stock (Group) Co.Ltd, are studied. When the modified bogie freight car are under different suspension parameters, the motion stability, curve negotiation behaviors and running response of the car are analyzed. The analyzed parameters include the across bar's position, friction coefficient of side bearing, the longitudinal clearance of side bearing, pre compression of side bearing's springs, and the axle box suspension. The results of this study are very useful to guide modifying design of the Zhuan 8A freight car bogies.
