We have developed an articulated-type small monorail car with good curving performance. This Small monorail car uses articulated trucks to reduce vehicle weight and is designed to negotiate a 40-m-radius sharp curve, enabling flexible track design in cities. A curving simulation algorithm for an articulated multi-car system has been developed by using inter-segment coordinate systems to connect separate segments, in which all displacements are sufficiently small to be linearly approximated. The curving dynamics of the car were evaluated using the proposed simulation algorithm. The simulation results showed that the yaw moment resistance between the car body and the truck can be reduced by using low-longitudinal-stiffness air springs. With the low-longitudinal-stiffness air springs we have improved the curving performance of the small type monorail car that can negotiate 40-m-radius sharp curve with small guide tire force and small slip angle of the running tires.
