Rubber pads should be avoided for vibration isolation because they can cause resonance between machines and foundations. Resonance leads to amplified vibrations instead of isolation, increased fatigue and breakdowns. Over time, rubber pads compress more which worsens the resonance issue. They also need frequent replacements that increase long-term costs compared to base isolators, which provide over 95% isolation and last lifelong with much lower dynamic loading and costs over 10 years.

1. EFFECTIVE VIBRATION ISOLATION
BASE Isolators Vs Rubber Pads

2. TECHNICALLY, WHY RUBBER PADS SHOULD BE AVOIDED?
RESONANCE
Very low compression
(under load) + Ageing,
causes RESONANCE
condition between
machine & the rubber pad.

3. TECHNICALLY, WHY RUBBER PADS SHOULD BE AVOIDED?
RESONANCE causes:
RESONANCE
 vibration AMPLIFICATION instead of vibration ISOLATION.
 high FATIGUE - poor machine life, frequent break downs.
 high dynamic loading of substructure

4. COMMERCIALLY, WHY RUBBER PADS SHOULD BE
AVOIDED?
Cost of using rubber pads…
 replacements every year (ageing & oil).
 losses due to machine breakdowns because of resonance.
 low machine availability.

5. COMPARISON
