Rollover Evaluation for the Bi-modal Tram on the Slope of Roadsides

초록

Since the bi-modal tram has no mechanical guidance track to guide and steer its running wheels, rollover on the slope of roadsides could be occurred by lateral deviation derived from lateral strong wind, unexpected flat tires, and automatic operation failures. Therefore, dynamic behavior on the slope of roadsides is one of the important evaluation factors for the rubber-tired vehicles without mechanical guidance track such as the bi-modal tram. In this paper, lateral behaviors and roll angles were analyzed as change of vehicle speed, vehicle approaching angle into slope, the slope angle of roadsides, and running track conditions when the bimodal tram enter into the slope of roadsides. Based on the results, it was evaluated whether lateral deviations could make rollover of the bi-modal tram on the slope of roadsides.
