新しい反転ねじり型の衝突エネルギー吸収構造体の開発

抄録

In order to improve the occurrence of the Euler buckling phenomenon which laterally bends when an impact load is applied to the elongated thin column structure in the axial direction and thereby greatly deteriorates the collision energy absorption performance of the structure, We proposed an inverted torsion type collision energy absorbing structure, developed experimental machining equipment, trial experiments, and examined in detail.
