On the basis of overall analyzing of suspended monorail vehicle bogie in Chiba Japan, the structure and connection of thecomponents were simplified, and the dynamic model of the vehicle by using ADAMS software was established. By using the maximumradial force of steering wheel as the evaluation index of vehicle curve negotiation performance, and considering the different vehiclespeed and the cornering stiffness of running wheel, the dynamic change rule of the radial force of steering wheel and its effect on theperformance of vehicle curve through was studied. The simulation indicates that suspended monorail vehicle has good performance incurve negotiation, and the radial force of steering wheel increases with vehicle speed and the cornering stiffness of running wheel.
