摘要
应用经验公式计算风电机组安装船风、流载荷,三维势流理论计算波浪载荷,将得到的风、浪、流环境载荷平均分配到单个桩腿。应用MSC.PATRAN-NASTRAN软件建立桩腿结构有限元模型,选取两种作业工况,分别施加边界条件及外载荷,作桩腿强度分析。计算结果表明,两种工况下,桩腿结构设计均满足强度要求。
In this paper, the environmental loads of wind, wave and current is obtained when using empirical formula and three-dimensional potential flow theory. By MSC. PATRAN -NSTRAN,FE model of a leg is found with the loads above and the leg strength is analyzed in two different situations. The result shows the structure design of a leg satisfies the strength requirements.
