Vibration Controls

Vibration controls are the application of force in an equal and opposite fashion to the forces imposed by external vibration. With vibration controls, a precision industrial process can be maintained on a platform essentially vibration-free.

It is known that many precision industrial processes cannot take place if the machinery is being affected by vibration. In this case, vibration controls are the solution to handle this problem. Vibration controls are now also commercially available for reducing vibration in helicopters, offering better comfort with less weight than traditional passive technologies.

Several components that are usually used by the typical vibration controls include a massive platform suspended by several active drivers (that may use voice coils, hydraulics, pneumatics, piezo-electric or other techniques), three accelerometers that measure acceleration in the three degrees of freedom, and an electronic amplifier system that amplifies and inverts the signals from the accelerometers. A PID controller can be used to get better performance than a simple inverting amplifier. For very large systems, pneumatic or hydraulic components that provide the high drive power are required.

Anti-vibration tools include vibration controls that are designed or mounted in ways. These tools help reduce the vibration level. For example, using anti-vibration chain saws reduces acceleration levels by a factor of about 10. These types of chain saws must be well maintained. Maintenance must include periodic replacement of shock absorbers. Some pneumatic tool companies manufacture anti-vibration tools such as anti-vibration pneumatic chipping hammers, pavement breakers and vibration-damped pneumatic riveting guns.

One of vibration controls you can choose in the market is the vibration controls that are produced by Moog’s wholly-owned subsidiary CSA Engineering, Inc. These vibration controls are the most demanding vibration and motion control solutions for aerospace and commercial applications.

You do not need to worry about their quality because over the past 25 years, Moog CSA has assisted commercial and military aerospace customers to provide satellite payload and vibration isolation systems, ground-based test systems, hexapods for space and missile systems, tuned mass dampers for vibration control, softride spacecraft isolation systems, shock test services, spacecraft jitter simulation, and modular satellite structures for rapid assembly.

Another option of vibration controls is AirLoc® PAD-PAK® Vibration Control Pad. This product is prepackaged to provide proper leveling and loading for machines having 4 points of support.

Offered in 45 durometer neoprene for low-frequency applications and 70 durometer nitrile for high damping, each set contains 4 base pads and 4 shim leveling pads. Cross pattern on tops and bottoms assures stable, non-slip surface.

Featuring a cross pattern on the tops and bottoms to assure a stable, non-slip surface for heavy machinery, AirLoc® PAD-PAK® Vibration Control Pad comes in sizes ranging from 2? to 10? sq. and varying thickness, to support overall machine weights ranging from 200 to 20,000 lbs. The base pad can be stacked, separated by the shim pad, for increased deflection. Related to its price, it depends upon load capacity.

Of course, there are still many options of vibration controls available for you out there. So, you do not need to worry that you cannot find the one you are looking for. The only thing you should do is making sure that your chosen vibration control is suitable with your needs.
