PRT차량의 곡선반경에 따른 최대주행가능속도 평가

초록

In this paper, we performed the dynamic analyses of a PRT vehicle, which is under development by KRRI, according to its driving scenarios, and derived the maximum speed of the PRT at the various curve radii and speeds under the ASCE-APM ride quality condition (lateral acceleration less than 0.25G). We also found the theoretical results of the maximum speed at the various curve radii and banks under the driving scenarios of PRT. Finally, we compared the theoretical results and the simulation results using Adams/car. From the comparisons, we found that they show similar results at the empty vehicle weight, because the mean error between the theoretical results and the simulation ones at the empty weight is only 1.51% as a mean value according to various speeds. But the mean error for the full load vehicle weight becomes larger, up to 10.74% as a mean value. We also found that the difference between the theoretical results and the simulation ones is similar because of the low limit velocity at which the ASCE-APM ride quality condition is satisfied.
