Study on Safety Structures for Human Friendly Robots, etc : Buckling behaviors and Ultimate loads of double-skin Rectangular Tubes due to Lateral Loads

Abstract

The final purpose of this study is to produce safety structures for human friendly robots. It is useful for the structures to absorb kinetic energy when the robots contact with person. Therefore, this paper proposes the rectangular tubes consist of corrugated-core sandwich skin (double skin) plates^<(1)> as a kind of safety structures, which is made up of aluminum sheet and paper. Their buckling-collapse behaviors and ultimate loads are discussed with FEA and experimental investigation with a Moire topography system.
