海上风电行业迅速发展，对风电安装船的研究更加值得关注。基于某自航自升式风电安装船，使用Sesam软件建立有限元模型。以安全性、经济性为目标，在倒K型原桩腿型式的基础上，比选K型、X型桩腿型式，分析风暴自存工况及作业工况下3种桩腿构型的结构重量、最大位移、各构件的屈服和屈曲强度（UC值）及抗倾覆能力，得出X型是风电安装船推荐的桩腿结构型式，为风电安装船桩腿选型提供参考。
With the rapid development of the offshore wind power industry, the research on wind power installation ships deserves more attention. Based on a self-propelled jack-up wind power installation vessel, a finite element model was established using SESAM software. Aiming at safety and economy, on the basis of the inverted K-type original leg type, the K-type and X-type leg types were compared and analyzed, and the three types of leg configurations are analyzed under the storm condition and operating condition. According to the structural weight, the maximum displacement, the yield and buckling strength (UC value) of each component, and the anti-overturning ability, it is concluded that the X-type is the more recommended pile leg structure type for this wind power installation ship, which provides a reference for the selection of pile legs for wind power installation ships.
