Vibration is undesirable in domains like engineered systems and habitable spaces, and methods have been developed to prevent the transfer of vibration to such systems. One of the ways to mitigate those vibrations is by “active vibration isolation” by employing electric power, sensors, actuators, and control systems. The other way is to use “passive vibration isolation” with techniques such as rubber pads or mechanical springs or wire rope isolators.
Wire Rope Isolators are durable and can withstand extreme environments. They are utilized in a variety of industrial and military devices. While such isolators are intended to protect the mounted item from shock and vibrations occurring along all three spatial dimensions or axes, as a practical matter the configuration of the isolators results in substantially greater stiffness and damping effect along one axis. Accordingly, a choice must be made as to the type of vibration of primary concern, with a response along the other axes being severely compromised.
The wire rope isolators have stainless steel cable and aluminum retaining bars, which provides excellent vibration isolation. The isolators are corrosion resistant, which makes them environmentally stable and high-performance in a variety of applications. The wire rope mounts are unaffected by harsh environmental conditions and temperatures, oils, abrasives, mycosis, humidity, ozone, grease, chemicals, nuclear radiation, ozone, dust and erosion of organic solvent. The compact wire rope isolator is smaller than a traditional wire rope and can absorb shock and vibration in small spaces. Single point mounting offers flexibility for integration into existing products. With versatile mounting options, crimping patterns, and size variation, wire rope shock absorber products can help your systems meet all requirements for industrial, defense, and commercial uses. Both compact wire rope isolators and wire rope isolators can be used on galley components where motors and fans produce vibrations onto surrounding structures.
A wire rope vibration isolator includes a coil of wire rope having a predetermined number of individual consecutive coils, a first crimp bar, and a second crimp bar. Each of the crimp bars is rectangular in shape and has a pair of opposing side surfaces. A series of lateral holes extending from one side surface to the other side surface of each of the bars is provided so that the predetermined number of individual consecutive coils may be threaded through the series of lateral holes of each of the bars. In this manner, when a crimping force is applied to each of the two crimp bars at a point where each of the individual coils passes through a respective bar, the coils are thereby secured in a fixed position relative to one another while remaining elastically deformable. A spring-like quality is thus imparted to the coil of wire rope so that the first crimp bar and the second crimp bar may move relative to each other to dissipate vibrational energy. This elastic support is for heavy-duty machinery such as generators and vibration isolation for delicate applications such as precision instruments, transportation of missiles and satellites, processors, communication units, protection for navigation and launching systems as well as large scale construction. The working temperature for wire rope isolators is -75°C－+175°C, up to +370°C and each wire rope isolator comes with softened non-linear stiffness. The performance of a wire rope isolator is dependent on its inherent elasticity and damping. The elastic spring function is created by the flexing of the cable that is wound and clamped into a loop. The damping function is the result of friction between the individual wires as the rope flexes. The exceptional advantages are:
- Combined isolation of shock and vibration
- High inherent damping
- Very wide temperature range
- Long product lifetime with no maintenance
- Excellent resistance to chemicals, seawater, ozone, radioactivity, and UV light
- Infinite customization possibilities
- Quick and inexpensive prototyping
