Abstract
Method and apparatus for suppressing cable dynamics in a device towed in water. The apparatus includes at least one section for suppression of motion, wherein the at least one section includes an axial motion suppression section; and the axial motion suppression section comprising equipment for the attenuation of axial vibrations in an electro-mechanical cable. The equipment is configured to produce a digressive stiffness curve.

An apparatus for cable dynamics suppression comprising:
- at least one section for suppression of motion, wherein the at least one section includes an axial motion suppression section;
- and
- the axial motion suppression section comprising equipment for the attenuation of axial vibrations in an electro-mechanical cable,
- wherein the equipment is configured to produce a digressive stiffness curve.
A method for preparing a cable dynamics isolator comprising:
- determining forces experienced by an electro-mechanical cable;
- determining a tension band for vibrations in the electro-mechanical cable caused by the forces experienced by electro-mechanical cable;
- selecting at least one of:
- one or more springs based on the determined tension bands, and one or more flexures based on the determined forces;
- and
- installing any of the selected one or more springs and one or more flexures within a housing to form a vibration mitigation assembly.
An apparatus for cable dynamics suppression comprising:
- a male coupling adapted to couple to a first component of an electro-mechanical cable;
- a female coupling adapted to couple to a second component of an electro-mechanical cable;
- an axial motion suppression section disposed in between the male coupling and the female coupling and comprising at least one spring arranged on a rod and adapted to attenuate axial vibrations in the electro-mechanical cable, wherein the rod is mechanically linked to either the male coupling or the female coupling and is adapted to compress the at least one disk spring when the male coupling and the female coupling are pulled away from each other;
- and
- a bending and rotational motion suppression section disposed between the male coupling and the female coupling and comprising at least one axis flexure and adapted to attenuate rotational and transverse vibrations in the electro-mechanical cable.
