Finite Element Analysis to Stringer of a Semi-Trailer

Abstract

In this research, 2D and 3D FEM model of one stringer of a semi-trailer was built. Mesh generation and boundary conditions definition was processed on FAST software. Effective stress distribution diagram was obtained after FEM analysis to stringe structure under various working conditions. Main stress concentration area was defined and causes for stress concentration was analyzed. After all, suggestion for improvement and structure optimization was given.
