Finite Element Analysis of a Guideway for Automated Transit Networks

Abstract

An asymmetric beam currently being utilized in a solar powered automated transit system was analyzed for its deflections, stresses, and angle of twist. Finite element analysis (FEA) with ANSYS was used in conjunction with hand calculations from beam theory to determine the response of the guideway to loading anticipated in normal operation. An iterative approach was used for modeling the system, where the geometry was taken from a simplified case and progressed in complexity until the original model was duplicated. After analysis, the deflections, stresses, and angles of twist were found to be within suitable ranges for a suspended transportation system.
