By their nature, wire rope isolators are self-snubbing, fail-safe, and captive to the ultimate limits of the metals. They are insensitive to temperature from cryogenic up to near anneal. They resist most industrial and natural environments. The VMC Group’s manufacturing process is set up to create special winding configurations to customize spring rate and deflection.

VMC Group presents tables of isolator recommendations based on the type of application and applied static weight per isolator. The indicated isolator is a convenient starting point when performing selection analysis.

The tables referenced are not a substitute for proper analysis of system requirements. The key elements to performing a meaningful selection and analysis are:Payload weight, geometry, center of gravity, isolator location

Quite often, we size the isolation system to do the best job within reasonable size constraints. Any theoretical isolator selection must be reconsidered in light of real-world limitations on equipment sway space and the isolator’s physical size and stability. Some very simple equations are used in selecting wire rope isolators. When considering shock, we use an energy method. We reduce a shock pulse to an equivalent velocity step. For a few typical shock inputs, the velocity steps are as follows:

With the spring rate (K) and dynamic displacement (Dd) established, we can now select an isolator. However, designers should take caution: The spring rates published are average. The placement of the static load on the load-deflection curve modifies the spring rate, available dynamic deflection capability, and cross-axes stability. The load-deflection curves for the principal and cross axes should be requested and considered when making any selection. VMC Group’s modeling software takes both the full third-order curve and damping into account.

Particularly with wire rope isolators, a robust system should be designed such that variances in the effective natural frequency due to dynamic damping do not significantly alter performance in the desired band.

VMC Group pioneered the wire rope isolator more than fifty years ago. Steel wire rope is strong, flexible, and fatigue-resistant because it is made up of many individual strands of high-tensile strength drawn wire. When bent or buckled, it is as much an elastic element as any tempered coil spring or elastomeric mount. Due to frictional forces between the individual strands, wire rope can provide a significant level of dynamic damping — typically 15% to 20% of critical damping. This level of damping makes wire rope isolators attractive for applications that involve sweeps through resonance and transients such as shock.

To create a shock and vibration isolator from wire rope, VMC Group creates buckling elements either in the form of helical loops (Helical Series isolators), or individual arcs (Arch and Circular Arch Series). Like any buckling element, a third-order force-deflection curve results. This can also be called a “softening curve.” Graphically, the curve starts from zero and is nearly linear. As load and deflection increase, the curve eventually begins to flatten. At some further point along the load-deflection curve, it becomes steeper, creating an inherent snubbing effect.

Shock is attenuated by spreading the input energy over time and distance. The flattened section of the curve is excellent for this. The load-deflection curve of a wire rope is very long given the isolator’s physical size. The isolator is a hollow, slender device capable of collapsing in on itself. For its size, it can deflect far more than elastomer and more than a coil spring. This is not to say that wire rope isolators are strictly shock attenuators and not vibration isolators. As an elastic element in a spring-mass system, it will exhibit a natural frequency and thereby form a low-pass filter for vibration energy in the same manner as any coil spring or elastomeric isolator. VMC Group does not list load ratings for individual wire rope isolators and we publish two different average spring rates. We have average static load-deflection curves available in both hard copy and electronic form for the principal isolator directions. They are always available on request. We have also chosen not to include load-deflection curves for wire rope isolators and encourage you to obtain assistance from VMC Group’s Engineering Services Division at 1-800- 569-8423. In almost all cases, application assistance, including analysis and modeling, is performed free of charge and without obligation to the customer.

To determine how much load can be placed on a wire rope isolator, we must first ask what the customer intends to do with the isolator. If small amplitude vibration is the input, we can place the static load along much of the lower two- thirds of a typical load-deflection curve. The effective static spring rate is the tangent of the curve at that load point. If large amplitudes, particularly deep shocks, are to be the input, we place the static load down in the linear first third of the curve. This allows the load to ride high up onto the curve in response to the shock. In this case, the effective average spring rate is a global straight-line, end-to-end slope of the curve over the excursion. To provide average values in the catalog for design purposes, we take the vibration spring rate as the tangent slope near zero and the shock spring rate as the overall end-to-end straight-line slope over the curve. VMC Group’s modeling software takes the entire third-order curve into account. The non-linear nature of the response curve and the presence of input-dependent damping are good reasons to work with our engineering department when selecting an isolator.

Another reason to consult with VMC Group before selecting your wire rope isolators is the interrelationship between the axes of the isolator. Wire rope isolators are elastic elements in all directions simultaneously. This makes them suited for all-attitude and mobile applications and applications that involve complex, off-axis inputs. The physics of the isolator is such that most inputs produce a response with components in more than one direction.

We can manage this characteristic using properly engineered solutions that take all axes into account. It should be noted that use of the tension direction for primary shock attenuation is not recommended. This is due to the predominance of tensile loading within the cable that results in a stiffening curve.

As the world leader in wire rope technology, our custom plate assemblies, and custom-designed isolators have been used in various applications for over 50 years. Whether for avionics and aerospace equipment, electronics apparatus, engine gensets, auxiliary power supplies, or other sensitive equipment requiring isolation, our engineering group will work with you throughout the entire design process to provide the custom solution you require. Our modeling software has an excellent reputation in the industry for its accuracy and will ensure your project is designed correctly from the beginning. Our plate assemblies and custom isolators have been designed to support weights from just a few pounds to over 100,000 pounds and take the form of special length bars, differing diameter wire, and winds, custom rail systems, plate assemblies, trays, and skids. Our helical wire rope isolators have been qualified on numerous military projects requiring the following typical specifications for shock and vibration:

CAVOFLEX® cable mounts are produced by WILLBRANDT from stainless steel ropes and aluminium bars. The advantages compared to conventional steel mounts or elastomer dampers lie in their high deformability for impact absorption and above average vibration damping.
