Description

technical field [0001] The invention relates to a system and a method, in particular to an automatic analysis system and method for an offshore wind turbine foundation structure. Background technique [0002] The development scale of offshore wind farms is relatively large, and the number of wind turbines is large, ranging from dozens to hundreds. The analysis of the foundation of wind turbines mainly includes limit condition analysis, modal analysis, and seismic response spectrum analysis. In the process of wind turbine infrastructure analysis, comparison and analysis of multiple models is usually required, and the geological parameters of each wind turbine borehole are also different. Using conventional software requires building models, calculating and analyzing, and extracting results one by one. There are many manual steps, which not only take a long time , low efficiency, and prone to mistakes, heavy audit workload. [0003] The foundation design of offshore wind turb...

Problems solved by technology

Due to the poor pertinence of this type of software, the operation efficiency of modeling analysis, result extraction, and code verification is low, and it cannot meet the needs of actual design projects for offshore wind turbine foundations.

Current ocean engineering professional software is more pertinent than general-purpose finite element software, but such software is widely used in the industry, and the basic input and output data of wind turbines are operated on multiple interfaces. There are mistakes, especially when analyzing the foundation of multiple wind turbines in a wind farm, it is necessary to manually repeat the operation of each wind turbine foundation one by one, which takes a long time and the degree of automation needs to be improved, making it difficult to adapt to the development trend of large-scale construction of offshore wind farms

[0005]In addition, during the foundation design process of offshore wind turbines, scheme changes, wind turbine manufacturer information changes, and geological parameters updates often occur, making calculation and analysis work more complicated

Simple and cumbersome repetitive work sometimes even affects the mood of designers, resulting in a decline in the quality of finite element analysis

[0006]Currently, there are few commercial software specially designed for offshore wind power foundations, related industries or general-purpose finite element software have many operation steps, input and output are difficult, and the pertinence is not strong.
