Abstract
Securing of the safety against the disaster which it suffers the speed-up of the machine and impact is requested. Some structure absorbs movement energy by thing to break pressure efficiently, and safety is secured in the impact design. Because it changes by the form of the composition member and the materiality, impact absorption performance must control the amount of energy absorption due to the deformation of the structure. In this report, it was examined about impact absorption performance to receive a impact load about the load direction and the buckling deformation experimentally.
