This refers to the ability to replicate the vehicle excitation that occurs in the real world to your product/package systems in order to witness the effects and identify weaknesses. Vibration occurs on all forms of transportation and at varying levels of intensity in the distribution environment. In the real world, vibration is complex and can intensify the natural frequencies within a product/package system. The cushioning of a package system also has a natural frequency. If the natural frequency of the product and the package coincide, damage is likely to occur. Most so called “hidden damage” during transit is likely caused by compound resonance.

Measuring the response of the package system to vibration inputwill help determine the ability of the package to attenuate the vibration input at the critical frequencies of the product, where it is most sensitive.

The testing is normally conducted on an electrohydraulic or an electrodynamic vibration test system, depending on the specimen mass and the frequency band to be covered.
