摘　　要：文章对操作条件下的爆破载荷、运输条件下甲板涌浪和撞击载荷,以及正常操作条件下的吊柱载荷进行了有限元分析,经FEMAP软件计算可知,操作条件下的爆破载荷、运输条件下甲板涌浪和撞击载荷的应力值均符合要求,吊柱载荷工况下,吊梁应安装在主甲板上,反力传递到舱壁的影响很小,接近0。根据结果,最大变形量为6.475 mm;最大变形区位于前防护罩防爆墙上门开口自由边缘附近。对海上浮式生产储油轮(FPSO)中正常工况下的庇护所结构有限元计算,具有一定的实用参考价值。The blasting load under operation conditions,the swell and impact load on the deck under transportation conditions,and the load on the Davit under normal operation conditions are analyzed by finite element method.According to the calculation by FEMAP software,the stress values of the swell and impact load on the deck under operation conditions and transportation conditions are all in accordance with the requirements.According to the results,the maximum deformation is 6.475 mm.The maximum deformation zone is located near the free edge of the upper door opening of the blast wall of the front shield.The finite element analysis of FPSO shelter structure under normal working conditions has some practical reference value.
