Resonance
Posted on 01/01/2019 Category:
Where the forcing frequency and the natural frequency of a suspended mass are the same i.e.; when the frequency ratio is equal to one, then the phenomenon known as resonance will occur. This is because the energy in the forcing motion is in phase with the natural frequency and energy is stored and builds up in the system. A good example of this is a playground swing where pushing the swing in phase the swing ark increases and the swing gets higher & higher. Rubber mounts must be designed to avoid amplification of the natural frequency of an installation.
