Abstract: This paper introduces the multiple-objectives optimization of the double circular tube made of aluminium foam under oblique load for numerous parameters of load angle and geometry. Thin-walled metallic tubes are used for the absorption of impact energy in vehicle systems, for example in bumper beams. In this paper, the aluminium alloy'AA6063 T6' foam filled tube that was clamped at both ends, at the bottom as boundary condition and at the top, the tube is applied with quasi-static load angle force ranging from 0 degree to 30 degree with respect to longitudinal direction of tubes.The finite element analysis using'ABAQUS code' was validated based on the applicable experimental data, and the tubes deformation modes were analysed. Using the Particle Swarm optimization algorithm (PSO), multiple-objective optimization design of crush parameters such as minimum peak crushing force and maximum specific energy absorption was performed.Different optimum designs were detected for different loading angles and double circular tube geometries.
