Metrology ensures that all types of products, whether it be for transportation or medical use, pass tests down to the finest details.
Testing engineers across industries perform routine checks on vehicles, aircraft and more to ensure their safety, efficiency and overall quality.
Of course, testing in any capacity is a sensitive process that external forces like vibration lead can negatively impact.
How do testing engineers solve this problem? It starts with a high-tech pneumatic vibration isolation system
What is Pneumatic Isolation?
Pneumatic isolation is a specific form of vibration isolation that is largely effective against low frequency vibration.
Vibration isolation is the process of isolating an object from the source of vibrations.
This object can be anything from a vehicle to a coordinate measurement machine.
Ultimately, pneumatic vibration isolation protects an object from external vibration by using a pneumatic vibration isolation system.
These systems create ideal conditions for testing equipment and heavy machinery for superior isolation from environmental vibration.
What are Pneumatic Isolators?
Using compressed air, pneumatic isolators maintain pressure in the “bladder” or “canister” portions of the device.
This air chamber within the pneumatic isolator is sealed with a flexible diaphragm that supports and isolates the payload.
Pneumatic isolators adjust their stiffness to accommodate the appropriate amount of pressure.
In return, the payload is isolated from its surrounding environment.
A complete pneumatic vibration isolation system ensures the best results for isolation and can accommodate large payloads like MRI machines and airplanes.
How does such a solution work? What are the applications of a pneumatic vibration isolation system?
How Is A Pneumatic Vibration Isolation System Used?
Companies use pneumatic isolators in a variety of industries for a wide breadth of applications.
Pneumatic isolators are essential for testing equipment featured in metrology, MRI machines, auto testing and aircraft testing.
An integral part of a vehicle’s certification, new and old cars alike undergo routine tests to assess their safety and efficacy.
In an industry like auto testing, pneumatic isolators isolate testing equipment and vehicles from external vibration.
Pneumatic vibration isolation systems have applications like dynamometers, engine test rigs, road simulators and much more.
As these applications may have high shock frequencies, the pneumatic isolators ensure they do not affect testing.
The aerospace industry uses pneumatic isolators to test the structural integrity of aircraft.
A pneumatic vibration isolation system simulates in-flight environments to assess an aircraft’s safety during aerospace testing.
Using pneumatic isolators, a Soft Support System hoists large aircraft from the ground and reduces outside influence from external vibration.
Therefore, the pneumatic isolators create a free-free environment to test for several key features.
Metrology, of course, is an industry that relies on accuracy and reliability.
The degree of precision required for precision machine tools is ever-increasing.
Precision equipment operates down to the smallest scales. Without proper isolation, inaccuracies and errors surface.
Pneumatic isolators reduce the influence of external vibration.
For proper cuts, turns, polishes and microscopic alterations, pneumatic isolators create ideal vibration-free environments.
Like precision machine tools, medical equipment should be free from any variables that obscure results.
MRI equipment is susceptible to vibration due to its sensitivity.
In this case, pneumatic isolators work as part of a system to isolate the MRI equipment.
The pneumatic isolators ensure vibration does not influence results by eliminating “ghosting” or double images.
