XWire Rope Isolators

VMC Group offers a variety of wire rope isolators that resolve shock and vibration issues in virtually any application. By selecting wire rope with the proper characteristics - wire diameter, number of strands, cable length, cable twist or lay, and the number of cables per section, we have created isolators that provide superior equipment protection. Ideally, passive isolation systems require no maintenance, use little space and keep functioning under varying temperatures and in corrosive environments.

As an elastic element, wire rope isolators will afford attenuation of vibration disturbances in much the same manner as they attenuate shock inputs. Wire rope isolators provide inherent damping by virtue of relative motion between wire strands. This damping limits vibration response peaks and limits responses to start-up and shut-down transients. 

Isolators must also attenuate shock with minimum dynamic travel. A design that buckles under heavy shock loads without bottoming or permanent deformation provides the large deflection needed to bring the impacts within acceptable limits. When shock load is applied, the isolators soften and deform. This displacement reduces the acceleration level, through the controlled buckling of the wire rope loops.

This wire rope design handles both shock and vibration. In addition, three-plane, all-axes isolation permits installation in any attitude - vertically, horizontally or laterally. These design features make very compact mounting systems possible for use in rotary wing aircraft.
