Vibrations are by far the dominant cause of failures for any technology/hardware whether it is used for deep sea exploration or in space borne vehicles. In many cases, vibration is undesirable, wasting energy and creating unwanted sound directly and indirectly resulting in about 65% of the failures. Such vibrations could be caused by imbalances in the rotating parts, uneven friction or the meshing of gear teeth. This short course highlights that catastrophes can be evaded if proper analysis is done by identifying frequencies that can cause failures and by taking safety measures i.e. reinforcing, plunging or eliminating such frequencies on the hardware will eradicate failures.
