Institute of Rail Vehicles, Southw est Jiaotong University, Chengdu 6 003 , China; 2. National Traction Pow er Laboratory, Southw est Jiaotong University, Chengdu 6 003 , China) : , Abstract The affecting forces of bogies w ith traditional fixed w heelsets independently rotating w heels and independently rotating w heels for rear w heelsets are analyzed theoretically. By comparing curving performance of three kinds of bogies based on wheel-rail lateral force, it is found that the bogie of independently rotating w heels for rear wheelset is the best one The. dynamic calculating model of a vehicle with independently rotating wheels for rear wheelsets is established. The affecting forces of bogie are analyzed by numerical simulation methods. The results show that theoretical and simulation analyses are identical basically. tab, 4 figs, 7 refs. : ; ; - ; Key words independently rotating wheels bogi
