    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 good guiding on curve. During curve negotiation, longitudinal coupling IRW bogie has enough wheel/rail longitudinal creep force compared with lateral coupling IRW bogie. The attack angle of leading wheelset is smaller and only half of the value of full IRW bogie. Wheel/rail wear significantly reduces, and is about one-third of the value of full IRW bogie. Other curving performance indexes are also superior to full IRW bogie. It can be seen that longitudinal coupling IRW bogie has good guiding capability.
