Umbilical bend-testing

摘要

Apparatus and methods related to umbilical bend-testing are described. For example, some embodiments may contain a three-level support structure, umbilical terminal locker, bending machine, compression testing device, and stress-strain collection system, and may be used for the bending fatigue endurance test for umbilical samples.

主权项

1. An apparatus for bend-testing a umbilical sample, comprising:
a support structure; a first umbilical terminal locker configured to lock a first end of the umbilical sample, the first umbilical terminal locker being translatable relative to the support structure; a second umbilical terminal locker configured to lock a second end of the umbilical sample, the second umbilical terminal locker being non-translatable relative to the support structure; a bending machine configured to (1) detachably connect to the first umbilical terminal locker and (2) detachably connect to the umbilical sample between the first and the second ends; a compression testing device configured to compress the umbilical sample along a transverse axis of the umbilical sample; and a stress-strain data collecting system.
