Embodiment Construction

[0026] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0027] Based on the structural dynamics of marine engineering, the present invention proposes an intelligent floating mooring structure cable breaking experiment simulation system to realize mooring analysis of marine floating structures in the laboratory, transient analysis of cable breaking, and transient dynamic response of floating structures Research and many other functions. In view of the sudden breakage of the mooring line 3, the transient dynamic response characteristics of the broken mooring line 3 and the marine structures are analyzed through experiments. For accurately simulating the transient motion response of marine structures in the case of mooring and cable breakage, monitoring the tension change in the mooring cable 3 is of...

Abstract

The invention discloses an intelligent floating-structure mooring and broken cable experiment simulation system. The intelligent floating-structure mooring and broken cable experiment simulation system comprises an experiment module, an intelligent broken cable device, a mooring cable and an intelligent control and monitoring system, wherein the intelligent broken cable device is fixedly arrangedat a position of a cable guide hole of the experiment model, one end of the mooring cable is fixedly arranged at the bottom of a pool, the other end of the mooring cable is connected to the intelligent broken cable device, the mooring cable is connected to the position of the cable guide hole of the experiment model by the intelligent broken cable device, the mooring cable and the experiment modelcan be disconnected by the intelligent broken cable device, the intelligent broken cable device is controlled to achieve broken cable control of the mooring cable by the intelligent control and monitoring system, and dynamic response monitoring of the experiment model and instantaneous tension monitoring of the mooring cable are achieved. Broken cable control of a floating mooring structure is simulated under an experiment condition, the instantaneous dynamic response of a floating body and the dynamic characteristic of the mooring cable can be accurately simulated when the mooring cable is broken, and the problem of broken cable instantaneous control and monitoring under the experiment condition is solved.

Description

technical field [0001] The invention relates to the analysis and experiment technology of marine floating structure mooring, in particular to an intelligent floating structure mooring and cable breaking experiment simulation system. Background technique [0002] When the floating structure is engaged in production activities in the operating sea area, its position and direction are generally maintained by the mooring system. As a permanently moored floating structure, the floating foundation and its mooring system must not only withstand mild sea conditions during its life cycle, but also inevitably encounter various sea conditions, fatigue, corrosion, etc. Mooring lines may break, which could affect the safety of the structure. [0003] In the design stage of marine floating structures, it is one of the necessary links to consider the damage analysis of the mooring system, and it is also one of the key elements that have an important impact on the safety of the entire syst...
