As for the structural design of the frame for roller coasters, the effect of the movement of bogie on the frame has not been cleared. Against this backgrounds, in this paper, the influence of movement of bogie on the main frame was evaluated based on results from the vibration test using U-shaped small-scale model and numerical analysis. In numerical analysis, an analytical method for calculating the acceleration due to the movement of the bogie was proposed and verified. Lastly, the safety factor for the structural design in confirming the seismic safety was proposed.
