摘　　要：为了解决某型船设备双层基座焊接方案评价问题,采用三维有限元方法,对5种拟定的焊接方案,进行了典型海浪载荷下的静力学分析。基于复合中心抽样策略,针对不同焊接方案,进行了有限元分析和计算,并对不同方案结果进行了对比。分析表明:采用L型焊接形式,焊接强度不够,裂纹容易产生,实际建造过程中应避免这种焊接形式。In order to solve the problem of weld strength analysis on double-deck pedestal in equipment for a certain ship,three-dimensional finite element method was used to study the static analysis under typical sea wave loads based on five proposed welding schemes.According to different welding plan,the finite element model was analyzed and calculated.The results show that the L type welding strength was not enough and the crack was easy to be produced,which should be avoided during the actual construction.
