摘　　要：法兰联结系统使用非常广泛的。将法兰联结系统作为一个整体,在外载作用下法兰联结系统受力与变形分析的基础上,对法兰环和螺栓的强度模糊可靠性进行了研究。算例的计算结果表明,本文的分析方法是有效的。The flanged connection system is wide-ranging applied With regard to this structure,the first requirement is that the strength of its connection components must be ensured in the case of clamping and operating.On the base of the load-deformation analysis of flanged connection system,the strength fuzzy reliabilities of the flange rings and bolts are investigated in detail when it is subjected to external bending loads.The example shows the presented methods of calcu- lating flange and bolt strength reliabilities are feasible.
