Fundamental study on dynamic behavior of unsymmetrical suspension bogie with independently rotating wheels

摘要

This paper presents the fundamental study on dynamic behavior of unsymmetrical suspension logie with independently rotating wheels for the trailing axle. The curving performance of this bogie was mainly evaluated with using test stand and was compared with theoretical analysis. Then the results of stand test was agree fairy well with theoretical analysis. And in the sharp curve, curing performance of bogie with it is more superior than that of conventional bogie.
