一种用于脐带缆用保护套管的弯曲疲劳试验机
By designing a bending fatigue testing machine that includes a bending device and a pipe clamping device, the working condition of the protective sleeve being wound on the pipe coil is simulated, which solves the problem that existing equipment cannot accurately evaluate bending fatigue strength and achieves more reliable and stable test results.

AI Technical Summary
Existing umbilical cable protective sleeve bending fatigue testing equipment is difficult to simulate the actual working conditions of it being wound on the tube coil, which makes the weld joint prone to breakage due to excessive stretching, and makes it impossible to accurately assess its bending fatigue strength in use.
A bending fatigue testing machine including a bending device and two left and right tube clamping devices was designed. The moving component and the rotating component simulate the working condition of the protective sleeve being wound on the tube coil, allowing the two ends of the sample tube to have the freedom of left and right movement and rotation, thus avoiding excessive stretching.
This improves the reliability and safety of test results, avoids weld fractures, and ensures the stability and accuracy of the test process.
