Measuring device and method for fluid conveying hose bending rigidity

The invention relates to a measuring device and method for fluid conveying hose bending rigidity. The measuring device for fluid conveying hose bending rigidity comprises a pair of guide rails and two experiment tables placed on the guide rails, and an experiment section is formed between the two experiment tables. The outer surface of the fluid inlet end of a fluid conveying pipe is sleeved with a pressure controller, a tensile machine is located one side of the fluid outlet end of the experiment section, the fluid conveying pipe is loaded through a double-lug sleeve arranged on the middle section of the fluid conveying pipe in a sleeving mode, and a force applying cylinder is hung at the lower end of a forcemeter. A distance measuring instrument is installed blow the force applying cylinder. The height of a camera lens is equal to the axial direction of the fluid conveying pipe, and the camera lens is located at the one second position between the two experiment tables. The measuring method for fluid convey
