基于载荷-强度干涉理论的压气机可靠性模型分析

Analysis of the reliability model of compressor based on the theory of interference between load and intensity

本文首先介绍了载荷-强度干涉理论和串联系统的独立系统可靠性模型、相关系统可靠性模型和次序统计量模型,然后通过假定压气机各级的分布函数,分别建立了压气机的三种可靠性模型,得到了压气机可靠性随其级数的变化关系,结果显示相关系统可靠性模型和次序统计量模型优于独立系统可靠性模型。

This paper introduces the theory of interference between load and intensity and the independent system model, the interrelated system model, the sequence statistic mode/of the system in series at first. Then three kinds of reliability model of compressor were set up and the correlation between the reliability of compressor and the number of compressor stage was found by choosing the distributing function of compressor stage. The results show that the interrelated system model and the sequence statistic model excel the independent system model.
