Vibration is a mechanical phenomenon causing oscillations around a fixed point. The vibration occurs when elastic bodies, like springs, are displaced from their equilibrium (fixed) positions due to external forces.. This is because when a body is moved by external application, internal forces in the form of elastic or tension energy are present.
The actual testing of machine is done by varying speed of motor and the corresponding amplitude is noted. Vibration exciters are used to produce cyclic excitation force at a required frequency. The cyclic excitation force produced by the exciter can be applied to the machine or structure to study its dynamic characteristics.
