摘　　要：为了研究Super M2自升式海洋钻井平台固桩架在预压、作业、暴风自存工况下的力学性能,文中对固桩架采用壳单元,通过建立固桩架、桩腿及支架处的力学模型,确定载荷的分布,并综合考虑了预压、作业、暴风自存各工况下水平载荷与垂直载荷的组合作用以及风载荷与船体夹角的影响,从而研究了固桩架在0°,30°,60°,90°,120°共5个特征角度时的力学特性,并以此为基础论述了船体和桩腿的连接刚度.研究结果表明:当特征角度为30°和90°时,固桩架导向产生最大应力;且在作业及暴风自存工况下,船体和桩腿的连接刚度分别为79.398 N/mm和82.445 N/mm.In order to investigate the mechanical performances of Super M 2 jack-up jacking frame under pre-load, working and storm self-existence condition , shell elements were used to mesh jacking frame in this paper . The distribution of the loads were determined by establishing the mechanical model of jacking frame , legs and the stents , comprehensive consideration of the combination effect of the horizontal load and the vertical load , and the effect of angle of wind load and the hull under pre-load, working and storm self-existence condition , and the me-chanical performances were proposed for degrees of 0°,30°,60°,90°and 120°under the condition of pre-load, working and storm self-existence , and discussed the connection stiffness of the hull and legs .The results showed that guides oriented maximum stress under the degree of 30°and 90°and the connection stiffness of the hull and legs were 79.398 N/mm and 82.445 N/mm under the working and storm self-existence condition respectively .
