Shock Fragility Test by Shock Machine

This test has been carried out to identify the shock fragility charactaristics by the shock machie.

It is very important to know the fragility of packged products to realize the appropriate package design.

If the product has a enough strength shock resistance, fewer cushion materials will be required to design package.

Here, the strength of product is represented as "Damege Boundary Curve" that is constructed by critical acceleration and critical velocity change.

These values are decided by shock fragility test.

"Critical velocity change" represent the resistance to free fall.

"Critical acceleration" value is used to cushioning package design.
All the packages are designed under this value when the drop test is performed.
