【 摘 要 】

Thin-walled tubes have been widely used as energy absorption structure. In this paper, the energy absorption properties of straight circular tube, straight sinusoidal tube and conical sinusoidal tube under oblique load were studied based on simulation analysis. The simulation model was validated by comparing with experiment. According to the simulation results, the straight circular tube is found to have the best crashworthiness performance under axial load. The crashworthiness performance of the conical sinusoidal tube is least influenced by the oblique load angle. The straight sinusoidal tube has the worst crashworthiness performance both under axial and oblique load.
