Abstract

The invention provides a test board for the torsional rigidity of a flexible body. The test board is used for simulating the condition of the flexible body under torsional moment and aims at solving the problems that an existing test board is fussy in structure and low in test accuracy. The test board for the torsional rigidity of the flexible body comprises a base part, a loading device and a limiting device, wherein the base part comprises a base, the flexible body and a loading cover plate; a to-be-tested flexible body is inversely arranged on the base and the loading cover plate is arranged at the upper part of the base; and the loading cover plate comprises two groups of hinge pivot shafts, vertical loads can be converted into torsional loads by using compressive deformation characteristics of the flexible body, and the test angle is limited through a limiting block and a limiting post in the limiting device. The test board for the torsional rigidity of the flexible body is high in test accuracy, compact in structure, simple in operation and large in loading range.

Description

technical field [0001] The invention relates to an external load loading test bench, in particular to a flexible body torsional rigidity test bench. Background technique [0002] The structure of the flexible body is similar to that of the elastic bearing. Its inner lining and outer shell are made of metal materials, and the inner structure is a metal sheet and rubber interlayer structure. An adhesive is added between the steel plate and the rubber, and finally it is made by high-temperature vulcanization. [0003] There are flexible bodies in the top and bottom tendon connectors of the TLP to provide flexibility for the tendons, thereby providing support for the TLP when it is affected by sea wind and waves, and it is its core force-bearing component. However, rubber is a kind of polymer material, and its material properties are typical hyperelasticity. Different from ordinary metal materials, after the rubber material is stressed, its mechanical properties cannot be accura...
