Controlled Translation Method of Affixing a Termination to a Tensile Member

摘要

A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with an internal cavity. The cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. The potting compound in one portion of the cavity is typically transitioned to a solid at a more rapid rate than other portions. Once the potting compound in one portion of the cavity has transitioned sufficiently to hold the filaments at the desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.

1. A method for adding a termination to an end of a tensile strength member made up of multiple synthetic filaments, said tensile strength member having a central axis, comprising:
a. providing an anchor with a proximal end, a distal end, and a cavity; b. said cavity including a distal region and a neck region; c. providing a potting compound in a liquid state, said potting compound being configured to transition to a solid state over time; d. placing a length of said filaments within said cavity; e. adding said potting compound in said liquid state to said cavity; f. monitoring for a defined transition of said potting compound from said liquid state toward said solid state; and g. upon detecting said defined transition and while at least a portion of said potting compound has not yet transitioned to said solid state, applying tension to said tensile strength member.
