Embodiment

[0064] like image 3 As shown, the overall structure of an existing submarine cable bending protector device, the dimension symbols of each position have been marked in detail. The submarine cable bending protector is a repetitive structure composed of multiple identical sub-structures. A section of the bending protector can be selected as the analysis object, which is convenient for subsequent optimization design when building a 3D model. models such as Figure 7 shown. The specific size of each part is obtained according to the formula relationship between Table 1 and Table 2, and the specific size of the three-dimensional model is shown in Table 3.

Abstract

The invention discloses a topological optimization design method of a submarine cable bending protector. The topological optimization design method comprises the following steps: establishing an initial three-dimensional model of the submarine cable bending protector; importing the initial three-dimensional model into an OptiStrut module of the HyperMesh software; meshing the initial three-dimensional model and defining material attributes of the initial three-dimensional model; performing topological optimization design on the three-dimensional model of the submarine cable bending protector;determining three load sets and two working conditions are created, loads and constraints of the load sets, and defining topological optimization design variables; selecting a topological optimizationmodel component to contain all design attributes in the initial three-dimensional model, defining a mass fraction lower limit value and an objective function of the initial three-dimensional model asminimum strain energy, and performing iterative optimization and calculation solution on the density of the submarine cable bending protector; and comparing the two-dimensional topological optimization design result with the three-dimensional topological optimization design result to verify the accuracy of the three-dimensional topological optimization design result.

Description

technical field [0001] The invention relates to the technical field of marine machinery, in particular to a topology optimization design method of a submarine cable bending protector. Background technique [0002] With 99% of transoceanic Internet data transmissions now being transmitted via submarine cables, the development of submarine cables has seen tremendous growth. Submarine cables are one of the key equipment for the development of offshore wind farms. In order to prevent the damage of the submarine cable near the pile foundation when it is in place, it is necessary to use a bending protector device to protect the submarine cable from bending. At present, the bending protector device industry in my country is in its infancy, and it is necessary to master the optimal design technology of the bending protector device as soon as possible. [0003] During the process of installation and in-situ operation of the submarine cable near the wind power pile foundation, it wi...
