摘　　要：应用随机-模糊概率模型,分析了钢制薄壁内压容器静强度在最苛刻压力试验条件下的可靠度。在压力试验和正常操作时,从控制钢制薄壁内压容器静强度可靠度范围的角度,对其与试验压力系数、超压限制系数及安全系数之间的关系进行定量研究,得到钢制薄壁内压容器的可靠性设计方法。The static strength reliability of steel thin wall ento-pressure vessel under harsh pressure tests terms is quantitatively analyzed based on the random-fuzzy probability model.Under pressure tests and normal operation,the relationship between reliability and three factors,such as safety factor,test pressure coefficient and overpressure confining coefficient,is quantitatively analyzed.The reliability design method of static strength for steel thin wall ento-pressure vessel is obtained.
