摘    要:文本比较详细地推导了厚壁筒结构在给定可靠度、置信度下的疲劳寿命计算公式,并利用一种快速、高效、精确的多线数值积分方法编制了计算机程序,对不同的厚壁筒结构尺寸、材料常数及随机变量的不同分布类型(常见的十种),该程序均可方便地求出其在一定可靠度、置信度下的疲劳寿命值.

关 键 词:厚壁筒,结构可靠性,疲劳寿命

Abstract:In this paper, the formulas which are used to calculate the fatigue lives of thickwalled cylinder structures are derived for given reliability and credit levels. A computer program is developed by using a fast,efficient and precise multiple dimensional numerical integration method. It is convenient to obtain the value of fatigue life of a thick-walled cylinder structure with various sizes, material constants, various types of variable distribution (for ordinary ten types) and various given reliability and credit levels.
Keywords:thick-walled cylinder  structural reliability  fatigue life
