Technical Support:. If the indicated information is available, the selection of an isolator will be greatly enhanced. The theory that follows in a further section is academic if the information to apply it is not available.

In the process of deciding on a vibration isolator for a particular application, there are a number of critical pieces of information which are necessary to define the desired functionality of the isolator. Some items are more critical than others, but all should be considered in order to select or design the appropriate product.

Weight, Size, Center-of-Gravity of the Equipment to be Isolated — The weight of the unit will have a direct bearing on the type and size of the isolator. The size or shape of the equipment can also affect the isolator design since this may dictate the type of attachment and the available space for the isolator. The center-of-gravity location is also important as isolators of different load capacities may be necessary at different points on the equipment due to weight distribution.

The locations of the isolators relative to the center-of-gravity — at the base of the equipment versus in the plane of the C. Types of Dynamic Disturbances to be Isolated — This is basic to the definition of the problem to be addressed by the isolator selection process. In many installations of military electronics equipment, random vibration tests have become commonplace and primary military specifications for the testing of this type of equipment such as MIL-STD have placed heavy emphasis on random vibration, tailored to the actual application.

Other equipment installations, such as in shipping containers, may require significant amounts of sinusoidal vibration testing. Shock tests are often required by many types of equipment. Such tests are meant to simulate those operational e. Static Loadings Other than Supported Weight — In addition to the weight and dynamic loadings which isolators must react, there are some static loads which can impact the selection of the isolator.

An example of such loading is the load imposed by an aircraft in a high-speed turn. This maneuver loading must be reacted by the isolator and can, if severe enough, necessitate an increase in the isolator size.

These loads are often superposed on the dynamic loads. Allowable System Response — This is another basic piece of information. In order to appropriately isolate a piece of equipment, the response side of the problem must be known.

The equipment manufacturer or user should have some knowledge of the fragility of the unit. This fragility, related to the specified dynamic loadings will allow the selection of an appropriate isolator. This may be expressed in terms of the vibration level versus frequency or the maximum shock loading which the equipment can endure without malfunctioning or breaking. The specification of allowable system response should include the maximum allowable motion of the isolated equipment.

This is important to the selection of an isolator since it may define some mechanical motion limiting feature which must be incorporated into the isolator design. In order to isolate to a certain degree, it is required that a definite amount of motion be allowed. Problems in this area typically arise when isolators are not considered early enough in the process of designing the equipment or the structural location of the equipment.

Ambient Environment — The environment in which the equipment is to be used is very important to the selection of an isolator. Within the topic of environment, temperature is by far the most critical item. Thus, it is quite important to know the temperatures to which the system will be exposed. The majority of common isolators are elastomeric. Elastomers tend to stiffen and gain damping at low temperatures and to soften and lose damping at elevated temperatures.

The amount of change depends on the type of elastomer selected for a particular installation. Other Environmental Effects — Effects from humidity, ozone, atmospheric pressure, altitude, etc. Some external factors that may not be thought of as environmental may impact on the selection of an isolator.If the source of compressed air is removed, the Optical Tabletop will lower until it securely rests on the supports and the table will no longer be isolated from floor vibrations.

On page 2 we have indicated that the cut off point for rubber bearings is about 5. This would mean that the incoming frequency should not be lower than The efficiency equation is based on the assumption that a structure is a lumped mass or a block of concrete that has no flexibility and an infinite resonance frequency.

It is also assumed that this rigid mass loads each isolator in accordance with the weight distribution as a lump mass at each location. This assumption is false.

Just as in the isolation of structural floors from machinery, the selection of a practical deflection is dependent on the sensitivity or rigidity of the structure and the various resonances of the structural elements. A lightly loaded structural floor might have a frequency as high as 7 Hz and fully loaded, 3 Hz. The frequency of the steel columns resting on the isolators might be very much higher. Concrete structures will transmit structurally induced noise over very large distances from the source with almost no attenuation.

We recently extended our own office building and some demolition was required. The construction workers were using small chipping hammers about feet from my office.

There was no air-borne sound transmission, but the structure-borne noise radiating from the ceiling made it seem like they were directly overhead. In mechanical isolation work we have found that when isolating vibration at frequencies as high as Hz, we have had to use air springs with a response of 3 Hz before the isolation was effective as the vibration was in the audible noise range.

Moving on to lower speed machinery at 30 Hz, we have had to use isolators with a response as low as 2 Hz a frequency ratio of 15 to 1 before we could solve the problem.

We have been involved in a number of jobs where the acoustician recognized that not only did the building not respond as one mass, but that the requirements for isolation varied in different parts of the structure.

The ground vibration dissipated with distance from the source, so lesser treatment would be satisfactory further from the railroad. In one application, the building contained office space, a cinema and a live theater. The rest was a plaza over a garage. The critical area was supported on spring mountings with a response of 3.

In another example, that portion of the building over the railroad tracks was supported on 2. Further away spring deflections were smaller and the frequency 3. The extreme areas were supported on 6.

While steel spring isolators do an excellent job of stopping vibration, it is very important that high frequency noise transmission is considered too.

Spring mountings can be manufactured to any capacity. However, it is generally not practical to go to these numbers as the horizontal stiffness of the spring drops in proportion to the vertical and the building becomes more responsive to wind loads.
