緩衝構造の座屈を想定した段ボール梱包貨物の落下衝撃シミュレーション方法の開発

抄録

In this research, in order to develop a simulation method of drop impact of cardboard, the anisotropic elastic modulus of corrugated cardboard is decided by material test and it is used to compare the drop test and the drop impact simulation and evaluate the maximum acceleration of the article . It is known that buckling occurs in the corrugated board at the time of a drop impact and greatly affects the maximum acceleration. The relationship between this buckling and the maximum acceleration is elucidated, and the aim is to establish a method of simulating fall impact of corrugated cardboard when considering buckling.
