Problems solved by technology

Each test can only form a bending radius simulation. If you want to do several sets of bending tests with different radii, you need to manufacture several fixed seats with different radii, which is very inconvenient to implement and operate.

Abstract

The invention relates to an experimental device used for testing minimum bending radius of an ocean flexible pipe cable. The experimental device is characterized by comprising two panels which are the same in shape and size and matched bolts, wherein the lower part of each panel is provided with horizontal bolt holes arranged into a horizontal line at intervals, the panels above the horizontal bolt holes are also provided with a plurality of groups of arc-shaped bolt holes, and each group of the arc-shaped bolt holes and the horizontal bolt holes can form configuration lines with different bending radiuses. The experimental device provided by the invention is simple to operate and convenient to manufacture and has the advantages of saving experimental time and reducing cost.

Description

technical field [0001] The invention relates to an experimental device, in particular to a variable bending radius experimental device for testing the minimum bending radius of a marine flexible pipe cable. Background technique [0002] With the gradual development of deep-water marine resource environment, flexible umbilical cables are more and more widely used in marine engineering. The biggest advantage of the flexible umbilical cable is that it is flexible and can have a small bending radius. This advantage makes it possible to lay the coiled pipe method, which greatly saves the laying cost; at the same time, it makes the storage and transportation of the long-distance umbilical cable very convenient. Therefore, it is necessary to fully consider various practical application conditions when designing, and design the minimum bending radius allowed by the umbilical cable. However, due to the complexity of the section of the flexible umbilical cable, after the design, it i...
