摘　　要：为了确定方舱在爆炸荷载作用下的极限承载能力和承受0.05MPa的冲击波荷载需要采取的加固措施,采用ANSYS MECHANICS/LS———DYNA有限元软件对某整体大板力舱的静、动力响应进行了数值计算。结果表明,船体的静、动力极限荷载分别为0.011 25MPa、0.020MPa;通过五种加固方案的比较和优选,得到了方舱的最佳加固方案,其成果可为方舱加固设计的抗爆试验方案提供参考。The purpose of this paper is to determine the ultimate bearing capacity of a square cabin under the exploisve load and the reinforcing measurements for its suffering 0.05MPa impact load.The software of ANSYS MECHANICS/LS-DYNA is applied to analyze the static and dynamical response of a certain whole square cabin.The results indicate the static and dynamical ultimae load is 0.01125MPa and 0.020MPa,respectively.Through omparing and optimally selecting five reinforcement schemes,the best reinforcement scheme of the square cabin is found.The results give a reference to the resistant-explosion experiment scheme for the reinforcing design of a square cabin.
