Abstract

This paper presents finite element simulations of axial crash behaviour and energy absorption characteristics of thin-walled tubes with variable cross-sections and different materials to investigate the design of an optimised energy absorbing street pole. With the conclusion of the desired variables for the design of an energy absorbing thin-walled tube, the tubes are placed 90 degrees to that of the base of the model street pole. Simulation of frontal impact of a vehicle and street pole are analysed and compared to that of the energy absorbing street pole concept. Studies are carried out by numerical simulation via the explicit finite element code LS-DYNA. Results compare the absorbed energy and the deflection of each variable, and recommend best design for the tube structure which improved vehicle crashworthiness.
