Abstract

The invention relates to a six-degree-of-freedom connector for an ultra-large floating body composed of modules. The six-degree-of-freedom connector comprises a central control room. An X-axis direction, a Y-axis direction and a Z-axis direction of the central control room are respectively provided with at least one damping device. Each damping device comprises a piston rod. One end of each piston rod is located in a limiting room of the central control room and the other end of each piston rod is rotatably connected with a base. A damping medium is arranged between each base and the central control room. Each base is fixedly connected with a testing tool. Each piston rod performs linear movement in the central control room. A rotary damping device is arranged between each piston rod and each base. A limiting plate fixedly connected with the end portion of each piston rod is arranged in each limiting room. The six-degree-of-freedom connector for the ultra-large floating body composed of modules has following beneficial effects: due to the emulation model experiment and the wave loading model test of a module flexible function for ultra-large floating body, detailed tests can be carried out on such aspects as structural stress, displacement measurement and dynamic loads; safety and applicability of the structure of the ultra-large floating body in the sea can be verified; and the basis for structural design and a calculating method of the ultra-large floating body in the sea is given.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a novel flexible connector applied between super-large floating body modules in the ocean. Background technique [0002] The ocean super-large floating body is composed of multiple modules connected front and rear through connectors. In the complex ocean environment, the super-large floating body bears huge wave loads, and the elastic deformation of the connector is extremely large. At the same time, the load on the connector has a static and dynamic phase. combined features. Accurate evaluation of the flexible connection performance of super-large floating body modules is of great significance to the structural safety of connectors and super-large floating bodies. At present, a large number of numerical values ​​are used for simulation, while functional simulation model tests and wave load model tests are still blank. Contents of the invention [0003] The applican...
