Therefore, it is particularly important to accurately and efficiently test the stiffness of the cable.
[0003] Cable stiffness testing methods are mostly implemented using simple loading and displacement measurement devices. These devices usually include a fixed fixture, a movable fixture, and a displacement sensor.

This makes the operation relatively cumbersome and has limitations for the stiffness performance test of new cable materials. Utility Model Content
