This paper describes a response analysis for a monorail car. The dynamic model of the monorail car, taking into account the influence of track irregularity on tire force, has been proposed A multi-body dynamics method was enhanced and applied to the monorail car system that included the proposed monorail car model. The equation of motion for this system was automatically derived using this multi-body dynamics method. Frequency response analysis in the lateral direction for the monorail car was executed and vibration mode of the monorail car was compared with that of a rail vehicle. The result showed that the acceleration of the rail vehicle was larger at 1-Hz frequency because of hunting motion. On the other hand, the acceleration of the monorail car was larger at 10Hz frequency because of the roll vibration mode of the truck produced by horizontal tire force.
