| Abstract: | From the angle of creep forces between wheels and rails,the guiding mechanism of longitudinal coupling bogie with independently rotating wheels(IRW) was studied.Full vehicle dynamics models of different IRW bogies were built,and the guiding performances of longitudinal coupling IRW bogie,lateral coupling IRW bogie and full IRW bogie were investigated and compared through numerical simulation.Calculation result shows that the longitudinal coupling IRW bogie has good centering ability on straight line and goo... |
