Reliability Modeling: k out of n Configutations

WebA combination of a k-th class of n elements is an unordered k-element group formed from a set of n elements. The elements are not repeated, and it does not matter the order of the group's elements. In mathematics, disordered groups are called sets and subsets. Their number is a combination number and is calculated as follows: Web本发明有益效果：本发明提出从螺纹连接件出发，以应力‑强度数据为基础，以k‑out‑of‑n模型为架构，联合概率分布函数，结合可靠度设计指标，给出基于多竞争失效模式下的紧固连接系统可靠性正向设计方法，解决目前传统基于安全系数法的设计很难精确进行复杂工况的应力‑强度匹配性设计 ...
