First, AVC wire rope isolators, pictured at left, are suitable for low-frequency damping with high deflections. Their function is to prevent damage to structures and preserve the correct operation of sensitive equipment, while also reducing noise. Applications include oil exploration, radio equipment and generator sets, blowers/fans, and other HVAC style installations. Stainless steel wire rope isolators have a long service life and can adapt to elastic displacement in all dimensions. This allows multi-directional isolation, with installation in many different orientations. They maintain excellent isolation performance under maximum shock in severe environmental conditions, for example chemical pollution or extreme temperatures. Those properties make them suitable for railway compressors, aviation and marine engineering as well as camera mounts on UAVs and robotic camera platforms.
Second, the sister range of AVM spring mounts, pictured bottom right, is excellent for low vibration with high deflections, combined with the higher frequency damping of rubber end pads. They suit acoustic and motor mountings where a wider range of vibrations and larger deflections are likely, and also where wind loads or asymmetric movement patterns are experienced, such as in engine starting.
At the other end of the scale, AVF metal cushions, pictured top right, provide a very compact solution to the needs of machine tool manufacturers. They are ideal for machine component mounting where space is at a premium but deflection is minimised – such as in electronics equipment or isolation of exhaust systems. These wire mesh vibration dampers can be used for pass-through mounting or with an inset machine screw for component retention.
Overall, these high-performance vibration dampers are used in compliance with safety regulations on vibration and noise (DL 81/2008). Stainless steel is chosen for many applications because it performs over a long lifespan with low-to-zero maintenance, and do not age in the same way as rubber isolators, the company says.
