One of the simplest descriptions of vibration isolation is the act of isolating a device, machine, or structure from its source of vibrations. Vibrations which is desirable in many application, plays a critical role in the industry. However, vibrations beyond a certain level can also be harmful for many applications and engineering systems. Effects of
vibrations could affect the life, stability and performance of any engineering system or structure. But with right isolation equipment’s like the wire rope isolatorsfor vibration dampening can help you control or rather limit the levels of vibration in a given system.
The mechanism of vibrations is to generate mechanical waves which travels or transfer to the mechanical chains to the elements of mechanical linkages. Technological advancements have devised two separate approach to tackle this undesirable vibration and reduce its effect for improved stability and performance. One of the approach which involves high investments of installing sensors and expensive actuators that generate disruptive interference to counters the mechanical vibrations. The method of countering mechanical vibration through sensors and actuators is grouped under Active vibration isolation. On the other hand, the second approach involves installation of material and mechanical elements that absorb and damp the undesirable vibrational energy. The method of isolating vibration by installation of dampening element is grouped under Passive vibration isolation. Passive vibration isolation offers minimum vibrational energy transfer at extremely low cost as compared to active vibration isolation. Various materials and mechanical elements that come under the passive vibration isolators includes equipment’s like the vibration isolation pads and wire rope isolators.
Wire rope isolators are devices that offers maximum resistance to the flow of vibration energy. Standard wire rope isolators are constructed from stainless steel stranded cables, threaded through aluminium alloy retaining bars that are mounted for effective shock and vibration isolation. Its high corrosion resistant property and all metal construction makes wire rope isolators stable, high performing vibration isolators that are resistant to temperature extremes, chemicals, oils, ozone and abrasives. Design and construction of wire rope isolator ensure maximum performance and stability in industrial and defence applications. Applications which require high vibrational isolation in minimum space, compact wire rope isolators are adopted. Compact wire rope isolators are generally lesser in dimensions as compared to the standard wire rope isolators, these uniquely designed wire rope isolators provide cost-effective, shock and vibration attenuation in areas where space is a major constraint.
They are very easy to install and offer single point installation. Unique in design and ease to install makes them versatile and easily adaptable to any applications. Unique compact design permits them to offer vibration isolation to single element in the system and ensures maximum isolation to the source of vibrations. The beauty of this smaller dimensions makes them an ideal choice for use in sensitive equipment’s and electronic devices.
While selecting a vibration isolator take in to account the level of shock and the average stiffness and deflection required in a Wire Rope Isolator. While robust construction of standard wire rope isolators offers complete stability to the entire mechanical system, the compact wire rope isolator is capable of providing isolation to the smallest element in system. Such wide range of flexibility offers free hand to designer for building a highly stable, effective and efficient system.
