Abstract

The invention discloses a design method applied to a mooring system, which comprises the following steps of: (1) setting wind power Ff in the horizontal direction as main power, taking the position ofa connecting point of an anchor and an anchor chain as an origin of coordinates, taking a seabed as an X axis and taking the direction vertical to the seabed as a Y axis, establishing a generalized coordinate system and drawing a coordinate schematic diagram; (2) carrying out stress analysis from top to bottom from the buoy, and sequentially establishing virtual work equations of the buoy, the steel pipe, the steel barrel, the heavy ball and the anchor chain; (3) solving a constraint virtual displacement equation of the buoy, the steel pipe, the steel barrel, the weight ball and the anchor chain according to the virtual work equation of the buoy, the steel pipe, the steel barrel, the weight ball and the anchor chain; (4) constructing an objective function from the generalized coordinate system; and (5) solving a nonlinear equation set composed of a virtual work equation and a constraint virtual displacement equation according to the objective function, and calculating the inclinationof the anchor chain, the steel barrel and the steel pipe, the depth of the buoy entering water and the floating range of the buoy.

Description

technical field [0001] The invention relates to the technical field of mooring systems, in particular to a design method applied to mooring systems. Background technique [0002] The transmission nodes of the shallow sea observation network are composed of buoy system, mooring system and underwater acoustic communication system (such as figure 1 shown). The buoy system of a certain type of transmission node can be simplified as a cylinder with a bottom diameter of 2m and a height of 2m, and the mass of the buoy is 1000kg. The mooring system consists of steel pipes, steel drums, weight balls, electric welded anchor chains and special anti-drag anchors. The quality of the anchor is 600kg, and the anchor chain adopts ordinary chain links without files. The common models and parameters of the near-shallow sea observation network are listed in the attached table. There are 4 sections of steel pipe, each section has a length of 1m and a diameter of 50mm, and the quality of each...
