摘　　要：对新研制的自升式修井平台悬臂梁及支承基座强度进行有限元计算仿真,得到整体应力分布规律,确定受力较大的部位,并进行现场应力测试实验。考虑到现场测试的不足,使用有限元计算仿真进行包括钻台、悬臂梁及支承基座自重的3种测试工况下整体结构的应力。结果表明,其结构最大应力值均小于钢材许用应力,满足设计要求;对较大应力处的艉部基座应力部位进行结构改进,使其应力降低,提高了整体结构的安全性。Stress distribution and the high stress area of the new Jack-up＇ s well work-over platform cantilever beam and the support pedestal were attained by finite element method. The stress spot test was conducted to verify the numerical simulation. The stress test was incomplete, so the stress of the cantilever beam and the support pedestal under three experimental operating condi- tions at the consideration of the drill floor weight, beam weight and the support pedestal weight was numerically simulated. The re- sults showed that both the cantilever beam and the support pedestal satisfy the safety requirements. The stress level was decreased with the structure improvement of the support pedestal which suffered large stress, thus increasing the safety of the whole structure.
