- GENERAL problems which arise in packaging design are treated, including a discussion of cushioning characteristics, fragility rating, and the energy concept of static and dynamic testing of cushion material.A nomogram is presented which can be of use in designing cushioning installations.The author suggests the following:
-
1.
For maximum vibration protection, the natural frequency of the cushioned package should be at least one-third of the lowest critical-component natural frequency in the equipment shipped.
-
2.
For necessary protection of equipment such as guided missiles, all-metal mounting systems of nonlinear design combined with a damping ratio of 20% should be employed.
