Bifunctional energy absorbing system for use in zone requiring integrity of component at low speed and absorption of energy at high speed has set of beams providing elastic behavior and elastoplastic behavior for low- and high-speed impact

摘要

A seat of beams provides elastic behavior relative to front impact loads at low speed, with the impactor having a large width. The set of beams provides elastoplastic behavior for absorbing energy due to impacts at high-speed and with the impactor having a small width.
