摘　　要：纯稳性丧失是IMO第二代完整稳性衡准的五种失效模式之一。为研究对纯稳性丧失薄弱性敏感的船型参数,以及船型参数变化对纯稳性丧失薄弱性的影响趋势,选取4种类型不同的5艘实船,利用CAESES软件对所选实船进行主要船型参数变化,共计生成180艘新船型,然后对所有船型进行第一层和第二层纯稳性丧失薄弱性衡准计算,分析各个船型参数变化对纯稳性丧失薄弱性的影响。经综合分析将船型参数按对纯稳性丧失薄弱性的敏感程度进行了排序,为纯稳性丧失薄弱性衡准对船舶设计及在国内的推广应用提供技术依据。Pure loss of stability is one of the 5 modes of stability failure for IMO 2nd generation intact stability criteria.Ship formation parameters sensitive to vulnerability of pure loss of stability are studied.5 real ships are selected,and total of 180 new ship types is produced with the help of software CAESES.Level 1 and Level 2 of pure loss of stability for all ship types are calculated and the influence of parameters on the vulnerability of pure loss of stability is analyzed,which provides technical basis for ship design and application of vulnerability criteria of pure loss to stability.
