ResumoRockets, aircraft and other vehicles experience random vibrations. Although random vibration test facilities have become widely available they have not totally superseded sine wave vibration tests, which continue to be specified. This is because sine tests retain diagnostic advantages, although they are likely to overtest some elements of an equipment, and to lead to unrepresentative patterns of damage. The paper discusses formulae for the level and duration of a sine wave test and how the uncertainties surrounding the assumptions made will lead to weight penalties if random vibration is not used for proof of design.
