PRT 차량의 수직이송장치 구조 안정성 평가를 위한 해석적 연구

초록

The personal rapid transit (PRT) system has been widely recognized as a promising new transportation system suitable for providing the transportation welfare benefits as well as complementing the role of existing mass transit systems. In particular, the vertical transfer concept for a PRT vehicle has been highly interested as a result of its potential for possibly more flexible and better compatible on-demand transport solution. In this study, the circulating conveyor-based vertical transfer device is considered preferable, and its representative advantages are capable of continuous transfer along with minimum headway time. However, since the vertical transport of a fully occupied vehicle operating on a road network is the first attempt, it is essential to assess the structural integrity in order to secure operational reliability as well as structural stability. This study presents numerical simulation results of static structural stability analysis using a commercial finite element method (FEM) solver (i.e., Ansys®). For this purpose, the stress and strain values of each component were calculated, and stress concentration regions were also evaluated. These results will be reflected in the future development stages for further improvement.
