钢制内压容器常规强度设计的可靠性初探

Reliability Study on Normal Intensity Design of Steel Internal-pressure Vessel

本文应用基于概率统计理论的可靠性设计方法中的强度———载荷干涉模型 ,讨论了钢制内压容器安全系数、可靠度系数及设计公式 (参数 )置信度之间的关系式 ,并用有关实验数据定量分析了三者之间的关系。

This article discusses the relation formula among the safety coefficient, reliability coefficient and confidence of design formula(parameter) for steel internal-pressure vessels on basis of intensity-load interference model in probability statistics theory. It also quantitively analyzes the relationship among above three parameters according to the experimental data.
