Performance Comparison
Isolation Effectiveness
You want your equipment to work quietly and smoothly. Picking the right vibration isolater helps a lot with isolation. Rubber mounts are best for stopping high-frequency vibration and noise. They soak up energy and quickly lower shaking. This makes rubber mounts great for sensitive electronics and devices.
Spring vibration isolators are better for low-frequency vibration and sudden shocks. They let things move more but can handle bigger force changes. You often see spring isolators in heavy machines and HVAC systems. These places need help with low-frequency vibration.
Note: Experts say you should find where the vibration comes from. This helps you control noise better. If you pick the wrong isolater, you may not get good vibration reduction.
Studies show both types can lower noise in equipment. Passive isolators like rubber and spring types cut noise well and do not cost too much. You get the best results when you match the isolater to your equipment and vibration frequency.
Load and Compression
You need to check how much weight the isolater can hold. Rubber mountssupport loads from 55 to 4000 lbs (25 to 1814 kg). Spring isolators, such as VibraSystems, can hold over 3000 lbs. This makes spring isolators good for heavy equipment.
Spring isolators can move more. Most springs move at least 0.8 inches (10mm). Some can move up to 2 inches (50mm) or even 4 inches (100mm) for special jobs. This extra movement helps big machines with vibration isolation.
Rubber mounts need the right load. If you put too much weight on them, they wear out faster and stop working well. Spring isolators need regular checks to make sure they work right. Rubber mounts need less care, but they can get old and change shape under heavy loads.
Frequency Range
You should always match the isolater to the vibration frequency you want to control. Rubber mounts work best for high-frequency vibration and noise. They give strong damping and quickly lower vibration. This makes them perfect for electronics, medical devices, and quiet places.
Spring vibration isolators are better for low-frequency vibration. They have a low natural frequency, so they can stop slow, heavy movements. But they have a small damping ratio. This means they can let more vibration through at some speeds, so you need to check the settings.
Rubber isolators: Best for high-frequency vibration, strong damping, and noise reduction.
Spring isolators: Best for low-frequency vibration, sudden shocks, and heavy loads.
Tip: Many people use both spring and rubber isolators at home. This mix gives strong damping and good isolation for many vibration types.
You should always check your site to see what kind of vibration you need to control. This helps you pick the best vibration isolation system for your equipment and space.
