Abstract: The generally accepted methods for vibration control of industrial equipment include; Force
Reduction, Mass Addition, Tuning, Isolation, and Damping. This paper will briefly introduce each
method, and describe practical methods for their application. Several scenarios and case studies will be
presented, with emphasis on pragmatic solutions to industrial vibration problems.
Keywords: vibration control
Notwithstanding the replacement of worn or ponents, such as damaged bearings, 5 basic
methods exist for vibration control of industrial equipment, as detailed below;
• Force Reduction of excitation inputs due to, for example, unbalance or misalignment, will decrease
the corresponding vibration response of the system.
• Mass Addition will reduce the effect (system response) of a constant excitation force.
• Tuning (changing) the natural frequency of a system ponent will reduce or eliminate
amplification due to resonance.
• Isolation rearranges the excitation forces to achieve some reduction or cancellation.
• Damping is the conversion of mechanical energy (vibrations) into
