Passive energy absorber structure adaptable to manage impact energy for different deformation targets and loads

摘要

An energy absorber is disclosed that includes a container that receives a plurality of tubular segments and at least one spacer. The container includes one side that is adapted to receive an impact from a first direction. The tubular segments are assembled into the container in a parallel array with a cylindrical axis-C of the segments oriented perpendicular to the first direction. The spacer is placed in the container with the tubular segments being arranged to be displaced within the container so that they compress the spacer when the impact force is received on the one side. The method of making the energy absorber comprises assembling the plurality of tubular segments having in a container and assembling at least one spacer inside the container to hold the tubular segments in place.
