The oscillator/"earthquake machine" was explored in 2006 in Episode 60 – "Earthquake Machine". The MythBusters made a device powered by electricity rather than steam. It produced vibrations that could be felt hundreds of feet away, but no earthquake shaking on the bridge they attached to; they judged that the claim that the device produced an ...
These machines are capable of producing three different types of vibration profile sine sweep, random vibration, and synthesized shock. In all three of these applications, the part under test will typically be instrumented with one or more accelerometers to measure component response to the vibration input.
Vibration (from Latin vibrāre 'to shake') is a mechanical phenomenon whereby oscillations occur about an equilibrium point.Vibration may be deterministic if the oscillations can be characterised precisely (e.g. the periodic motion of a pendulum), or random if the oscillations can only be analysed statistically (e.g. the movement of a tire on a gravel road).
A vibration powered generator is a type of electric generator that converts the kinetic energy from vibration into electrical energy.
Vibration problems generally result in noise, bad surface quality and sometimes tool breakage. The main sources are of two types: forced vibrations and self-generated vibrations. Forced vibrations are mainly generated by interrupted cutting (inherent to milling), runout, or vibrations from outside the machine.
Over time, several additions to the machine were made, such as butterfly attachments and leg extensions. The newest product addition is the Soloflex Whole Body Vibration (WBV) Platform. Vibrating while you are lifting weights is thought to magnify the conditioning effects to help promote faster muscle growth.
