AN INTRODUCTION TO THE SHOCK RESPONSE SPECTRUM
www.vibrationdata.comAnother approach is needed for testing. X The shock response spectrum is a useful tool for estimating the damage potential of a shock pulse, as well as for test level specification. Note that MIL-STD-1540C and MIL- ... 2 In contrast, the level at a center frequency in a random vibration …
GUIDELINES ON STABILITY TESTING OF COSMETIC PRODUCTS
www.packagingconsultancy.comMechanical shock testing is often conducted in order to determine whether or not shipping movements may damage the cosmetic and/or its packaging. Vibration testing can help to determine for example whether de-mixing (separation) of powders or granular products is likely to occur.

Vibration Testing - NASA
www.nasa.govto evaluate all aspects of structural dynamics, including vibration, vibroacoustics, modal character-istics, sound transmission loss, and shock testing. Ground testing to simulate launch-induced vibration or to investigate structural dynamic characteristics has proven to be vital in developing successful spacecraft programs.
A Brief Tutorial on Machine Vibration
www.machinedyn.comIf the vibration is deemed to be serious, then this takes us to the second fork in the flowchart—forced versus natural vibration. This requires additional testing; usually stopping the machine to do resonance testing, a visual inspection, cleaning if necessary, and runout measurements with a dial indicator. The reason for
