(ii) Isolation of the source
Modify the transmission path of vibration between source and the system to protect the system.
Example - Insertion of resilient elements – Springs, Dampers, Viscoelastic Materials, Pneumatic Suspension etc. between the source and the system.
Very often vibration isolators are developed using a combination of springs and dampers. For example, viscoelastic materials are bonded to metal fasteners and used as anti-vibration mounts or isolators. The construction of a typical bonded rubber spring for use under compressive loading is shown below.
