漂浮式风力机张力腿平台“拟静力”结构强度分析
Quasi-static and structural strength analysis of tension leg platform for floating wind turbine
摘要
Abstract
Mechanical analysis of tension leg platform (TLP) structure under loads of the external environment is an important research for TLP.Under the combined effects of three types of environment loads in extreme sea conditions of wind,waves and currents,of the structure intensity of TLP was analyzed using ANSYS software as well as quasi-static analysis.Stress concentration areas of platform were improved locally by adding a support plate,and the improved platform was simulated and tested again.The results showed that,structure in the center and top of the column had a large amount of deformation.Stress concentration occurred in the connection area of the top and bottom of the platform and the column.By adding a support plate in the areas with stress concentration,the stress distribution for local area could be significantly improved and the stress concentration can be reduced in stress concentration areas.The research provides references for the structural design of the platform and further optimization.关键词
