石油机械的可靠性设计

Reliability Design of Petroleum Equipment

以设计变量随机化为基本出发点的机械强度可靠性设计新方法,比常规设计方法更能符合实际工程需要。本文重点介绍可靠性设计中强度概率计算法的基本理论,设计参数的确定及安全系教与可靠度之间的关系;通过计算实例说明概率设计法的应用。

The method of reliability-design of the mechanical strength based on the probabilistic design methodology conforms to the actual engineering requirement closer than the conventional design method. This article lays emphasis on the basic theory of probabilistic design methodology, the method for determining the design parameters and the relation, between salty factor and reliability level, and explains by example the application of this method.
