摘    要:针对失效域与超椭球凸集合发生干涉与不发生干涉两种情况下,超椭球凸集合非概率可靠性与非概率可靠度两种指标各自存在的不足,将两指标相结合提出多个超椭球凸集合描述时的可靠性综合指标定义,并提出将改进的有限步长迭代法(MLSA)与Monte-Carlo法结合来求解综合指标的方法.MLSA是在有限步长迭代法的基础上提出的,根据增...

关 键 词:超椭球凸集合  可靠性综合指标  改进的有限步长迭代法  Monte-Carlo法  评价函数  超空泡射弹  屈曲可靠性

Abstract:Both for the cases when a failure field and a super-ellipsoid convex set interfere or don't interfere with each other,there exists insufficiency of both the super-ellipsoid convex sets non-probabilistic reliability index and non-probabilistic reliability degree index.In view of this,this paper presents a definition of reliability comprehensive index based on multi-ellipsoid convex sets by combining the above two definition indexes.The comprehensive index is calculated by the combined method of modified limi...
Keywords:super-ellipsoid convex set  reliability comprehensive index  modified limit step length iteration algorithm  Monte-Carlo method  merit function  supercavitating projectile  buckling reliability
