IMPACT-ABSORBING COMPONENT

摘要

Provided is an impact-absorbing component for which: stable accordion-shaped collapsing deformation is possible regardless of the direction of the impact load; the buckling wavelength is small; and the buckling load is large. The laminated metal sheet (9) (impact-absorbing component) is configured by the maximum circumference of the component cross-section comprising 50% or more of a member, which is a laminated metal sheet (9) having surface layers (5A, 5B) obtained from metal sheets with higher Young's modulus and density than a core layer (10) laminated on both surfaces of the core layer (10) and which has been formed in a shape having at least two ridge lines (3). The ratio (tc/tf) of the thickness of the core layer (tc) to the thickness of the surface layers (5A, 5B) (tf) is 10.0 or less.
