摘要
以2种具有典型结构设计形式的桩靴为研究对象,依据规范要求进行工况设计与载荷分析,利用有限元软件MSC Patran/Nastran建立有限元模型并进行强度计算,得到各工况下桩靴的应力分布,分析得到预压载工况下接触面积与应力大小的关系以及偏心工况下偏心形式对结构强度的影响,根据有限元计算结果分析2种桩靴的结构性能优势。
Taking two types of jack-up unit spudcan with typical design as examples, the load cases were designed and the loads were calculated based on related rules. The FE models of two types of spudcan were established to carry out the strength calculation and check by MSC Patran/Nastran. Based on the preload condition, the relationship between the contact area and the maximum stress can be obtained. According to the eccentric condition, the influences of different eccentric types on strength can be witnessed. The structural performance of these two types of spudcan was compared with to analyze the advantages of each spudcan.
