摘要
可靠性设计法是化工容器强度设计的发展方向;利用了现有国家标准中的保证度系数和材料的变异系数,把标准值和随机变量的均值、偏差值联系起来;通过可靠性中心安全系数,建立了强度和应力的关系式,并应用算例加以说明。
It is shaoed that method of reliability design is developing direction of strength design of pressure vessel. Standard value ,mean value and deviation value of randon variable are contacted by a coefficient of guarantee degree and coefficient of variation in national standard, A equation between the strength of the steel and stress is set up by center safety coefficient of reliabilitity, and it is illustrated with examples.
