| Abstract: | A theoretical analysis has been carried out on the effects of shape misalignment of a three-piece bogie regarding the dynamic performances on straight track. Four types of basic misalignments has been classified and investigated respectively for lateral misalignment of wheelsets, lateral guiding forces, attack angles and wear work on contact points. The results show the importance and possible methods of controlling of these misalignments. |
