基于盲数的螺栓可靠性计算

Bolt reliability computing-algorithm based on blind number

基于未确知理论中盲数的概念和运算规则,建立了盲数强度应力可靠度计算模型,并用LabVIEW语言编写了相应的计算程序.通过对螺栓的实际可靠度计算,并与传统可靠度设计进行了对比分析,验证了模型的有效性和实用性.

This paper describes the blind-number stress-strength reliable computation-model established on the basis of the concept and operations of blind number in Uncertain Theory and offers the corresponding computation program in LabVIEW. In addition, test on the validity and practicability of this model is also conducted by comparing the result of bolt reliability gained from this model with that obtained from the traditional reliability-design method.
