Abstract
We developed the optimum cushioning design method for the product with a step. In addition, we investigated how the step of a product influenced the optimum shape of cushion by the simulation of this optimum cushioning design method. The main results obtained are as follows :
(1)The optimum shape of cushion Ⅱ (the cushion at the convex side of product) isn’t influenced by the length of the shape.
(2)The area of cushion Ⅰ (the cushion at the concave side of product) decreased with the length of the step monotonously while the cushion is stable for the buckling. And while the cushion is the shape of limitation of buckling, it increased monotonously.
(3)Both of the volume of cushions and the cost of package materials leveled off with the length of the step while the cushion is stable for the buckling. And they increased with the length of step monotonously while the
Cushion is the shape of limitation of buckling.
(4)In minimizing the thickness of cushion, even if the product has a small step, the area of cushion Ⅰ, the volume of cushion and the cost of packaging materials can be reduced.
