Shock tests are often required by many types of equipment. Other equipment installations, such as in shipping containers, may require significant amounts of sinusoidal vibration testing. 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-810) have placed heavy emphasis on random vibration, tailored to the actual application. Typically, sinusoidal and/or random vibration spectra will be defined for the application. In order to make an educated selection or design of a vibration/shock isolator, this type of information must be defined as well as possible.
Types of Dynamic Disturbances to be Isolated - This is basic to the definition of the problem to be addressed by the isolator selection process. The locations of the isolators relative to the center-of-gravity - at the base of the equipment versus in the plane of the C.G., for example - could also affect the design of 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 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.
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. Some of the factors which must be considered are: Some items are more critical than others, but all should be considered in order to select or design the appropriate product.
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. LORD Corporation's vibration and noise control experts can analyze your individual requirements and provide the most effective and affordable product solutions.Considerations in Selecting a Vibration Isolator They are designed to support and protect equipment in all types of industrial applications. LORD offers many standard products to meet most applications as well as custom-designed vibration isolators or a combination of LORD products. LORD Corporation vibration isolators set the standard for compact, high-load, high-capacity anti-vibration mounts. Elastomeric vibration isolators provide cost-effective solutions to problems involving vibration, shock and structural noise control. They will operate more smoothly and quietly, and they will be less disturbing to surrounding equipment and personnel, less susceptible to damage and less expensive to make. Vibration isolators, properly applied, will improve your products. Our customizable portfolio of LORD Elastomeric Mounts and Bushings provide simple, reliable and cost-effective solutions to isolate vibration and shock, accommodate motion, and decrease noise.
