【 摘 要 】

Various thin-walled (TW) tubular components have been widely applied to absorb impact energy due to their sound crashworthiness and long stroke. This paper presents a novel spiral TW tubular component used for absorbing energy. The presented TW structural component is easily prepared and cost-effective because it can be handily manufactured by sheet metal rolling. Its geometry structure on cross section is spiral so it is called spiral TW tube in this work, which was studied by formulation method. Furthermore, its dynamic crushing and energy absorbing characteristics under impact loading was investigated by means of simulation analysis. The analysis result shows that the presented spiral TW tube has a superior energy absorbing performance and is promising used in passive safety area.
