ABSTRACT:
A vibration isolation module (30) includes termination members (34, 36) at each end to which are connected electrical wires or cable (39), and a braided rope of aramid fiber (32). A plurality of compliant members (40) of polyurethane hose having tapered ends are inserted at intervals within the braided strands of the rope (32). Some of the compliant members (40) may be filled solid with polyurethane. Variable lengths of hose or variable diameters and wall thicknesses may be used to vary the compliance of the compliant members (40). Between the compliant members (40) are positioned a number of spacer members (38) which provide support for the hose (37) and electrical wires (39). This structure is carried within an oil filled stretchable hose (37) fastened to the termination members. When the module (30) is subjected to forces in tension, the load is carried by the aramid fiber rope (32) which, as the load is increased, tends to squeeze down and compress the compliant members (40).
