| Abstract: | Deformation model and energy absorption characteristics of a thin‐walled component with circular cross section are studied . To improve the relationship between axial force‐crushing and displacement during the collision process , the thin‐walled structure is modified based on the pre‐distortion theory .Induced convex grooves ,concave grooves and alternate convex‐concave grooves are set on the structure ,and finite element software Ls‐dyna is used to verity the feasibility of the method . |

| Keywords: | thin-walled components induced grooves crashworthiness |
