Abstract

This issue is the Part 2 of papers submitted to a call by International Journal of Vehicle Structures and Systems on Structural Impact and Crashworthiness. The division of the papers between the two parts was only due to the editorial and refereeing matters and there is no priority among the papers. As mentioned before the goal of these Special Issues is to provide a broad, but by no means comprehensive cross-section of some of the current research in the field of Structural Impact and Crashworthiness. Papers presented in this issue describe advances in research and application in the related area. They reflect enormous research effort of all the participants and substantial research funding commitments from various government bodies in different countries and the wider community.

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.

Keywords

Energy Absorption, Thin-Walled Structures, Vehicle Impact, Finite Element Analysis, Design Optimization.
