Wear: Old parts like bearings or gears make more noise and shake more.
Looseness: Loose parts can rattle and move around.
Ground vibration: Cars or machines nearby can make the floor shake.
Acoustic noise: Air from vents or speakers can be loud and distracting.
Direct force disturbances: Moving parts can push or pull on machines, making noise.
Noise and vibration come from many places. If you know where they start, you can find the best way to fix them.
Types of Vibration Isolators
If you want to lower noise and shaking, you have choices. Each vibration isolator works in its own way. The table below shows the main types and what they are made from:
Type of Vibration Isolator | Material Used |
|---|---|
Passive Isolation Systems | Rubber |
Active Isolation Systems | Metal |
Damping Systems | Composite |
Base Isolation Systems | Foam |
Spring |
Rubber Mounting Isolators
Rubber mounting isolators use rubber’s bendy nature to stop shaking. You often see them in engines, generators, and compressors. Their main job is to keep vibration and noise from spreading to other parts. Rubber mounting isolators are good for high-frequency vibration and noise. They are simple to put in and do not need much care.
Rubber mounts use rubber that bends and goes back to shape.
Rubber isolators soak up shocks and change vibration into heat.
Rubber mounting isolators hold heavy things and keep machines quiet.
You can use rubber mounts where you need easy, strong vibration control.
Rubber isolators are not best for very big or slow shaking, but they work well most times.
Note: Rubber mounting isolators are great for high-frequency noise and vibration.
Spring Isolators
Spring isolators use steel springs to keep machines apart from their base. You find spring isolators in HVAC systems and power equipment. These isolators are better than rubber mounts for low-frequency shaking. Spring isolators let machines move a little, which helps stop vibration from spreading.
Spring isolators use metal springs and sometimes rubber pads.
They let machines move more, which helps with big or slow shaking.
Spring isolators are good for heavy machines that need more support.
You can change spring isolators to fit different weights and needs.
Spring isolators last a long time and help keep machines safe.
Air Mounts
Air mounts use air-filled spaces to hold and separate equipment. You see air mounts where you need things to run very smooth and quiet, like labs or sensitive machines. Air mounts can change to hold more or less weight by adding or letting out air.
Air mounts use special valves to control air and stay steady.
They act like shock absorbers and stop shaking from reaching the floor.
Air mounts work for both high and low-frequency shaking.
You can use air mounts for equipment that needs the best vibration control.
Air mounts are great for keeping delicate machines safe.
Air mounts, spring isolators, and rubber mounting isolators all help lower noise and shaking. Rubber mounts are best for high-frequency noise, while spring isolators and air mounts are better for big or slow shaking.
How They Work
Rubber Mounting Isolators: Mechanism
Rubber mounting isolators use rubber to stop shaking and noise. When a machine moves, the rubber bends and stretches. This bending soaks up the vibration’s energy and turns it into heat. The room gets quieter and shakes less.
Rubber materials can soak up vibration energy by rubbing inside and making heat. Rubber compensators are bendy, so they can take in and block shaking by bending and changing shape when pushed.
High hysteresis rubber works even better for this job. When you press and let go, it makes a loop shape. This loop shows how the rubber uses friction and its special stretch to lose energy. The rubber’s stretch is slower than the force you put on it, so it soaks up more shaking. This gives strong vibration control, especially for fast shaking.
Rubber mounts soak up vibration energy inside the rubber.
Good isolation needs the right mix of stiffness and soaking up.
Rubber isolators protect in three ways, so your equipment is safe from shaking from any side.
Spring Isolators: Mechanism
Spring isolators use metal springs to keep machines off the floor. When the machine shakes, the spring stretches and squeezes. This lets the spring take in the movement and stops most shaking from passing through.
Passive isolation systems use weight, springs, and soaking up parts. They work like bouncing systems.
The natural bounce depends on weight and spring tightness. This changes how well the isolator blocks shaking.
Steel springs are great for stopping shaking, especially for heavy machines.
Feature | Rubber Isolators | Spring Isolators |
|---|---|---|
Damping Effectiveness | Works best for fast shaking | Better for slow to medium shaking |
Energy Absorption | Soaks up energy and calms shaking | Holds heavy things, less soaking up |
Frequency Range | Not as good for slow shaking | Works for many types of shaking |
Durability | Can wear out over time | Lasts long, stands up to weather |
Ideal Applications | Makes quiet rooms with less noise | Used in factories with big machines |
Air Mounts: Mechanism
Air mounts use air pockets to hold up your equipment. When the machine moves, the air inside changes pressure. This helps soak up the shaking and keeps it from reaching the ground.
Air mounts work like soft shock absorbers.
You can change the air pressure for your equipment’s weight.
Air mounts help with both fast and slow shaking.
They give smooth, steady support, which is good for delicate machines.
You can use air mounts when you need the best control, like in labs or with sensitive tools.
Vibration Isolation Performance
Rubber Mounts
Rubber mounts work well for stopping fast shaking. When machines run quickly, these mounts help stop the shaking and lower noise. Rubber mounts are best for high-frequency shaking, like in engines or small motors. Tests show that rubber mounts with two layers can block more shaking. This is because they have lower dynamic stiffness. As the shaking gets faster, rubber mounts do an even better job.
Rubber mounts can handle shaking up to 5000 Hz. This makes them a good pick for cars, planes, and other places with fast-moving parts. In lab tests, rubber mounts often lower noise better than spring isolators. These tests use special tools to measure sound, so you know how much quieter things get.
You get more benefits if you use neoprene or nitrile rubber mounts. Nitrile rubber does not break down in oil, fuel, or gas. This makes it good for greasy or oily places. Neoprene rubber stands up to sun, ozone, and bad weather. It lasts longer outside or in tough spots. Both types help your mounts last longer and keep working well.
Tip: Rubber mounts protect your equipment from shaking in all directions.
Spring Isolators
Spring isolators are best for stopping slow shaking. If you have big machines or large HVAC units, spring isolators work great. They use metal springs to let your equipment move a bit. This helps block slow, strong shaking. Spring isolators do better than rubber mounts for slow shaking.
Here is a table to show how spring and rubber mounts work for slow shaking:
Type of Mount | Performance in Low-Frequency Isolation | Additional Notes |
|---|---|---|
Spring Vibration Isolators | Excellent | Great for big machines and large HVAC units. |
Rubber Vibration Isolators | Moderate | Good for jobs that are not too hard. |
Spring isolators last a long time and hold heavy things. Some have rubber pads for extra shock help, but the spring does most of the work. Sometimes, special noise control parts are added to spring systems. These can help in labs or real-world places.
Air Mounts
Air mounts are best for stopping both fast and slow shaking. These mounts use air chambers to hold your equipment. You can change the air pressure to fit your machine’s weight. Air mounts act like soft pillows, giving smooth support and great shock help.
Air springs work best at very slow shaking, between 1.5 and 5 Hz. This means they can block slow, strong shaking from reaching the floor. When the shaking is faster than the air mount’s natural speed, they block even more. Air mounts act like filters, letting slow moves pass but stopping fast shaking. This makes them great for labs, sensitive tools, or places that need to be very quiet.
You can trust air mounts to keep your equipment safe from both quick and slow shaking. They give you the best vibration isolation, especially for delicate machines.
Note: If you need to stop both fast and slow shaking, air mounts are the most flexible choice.
