摘　　要：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 L ab VIEW语言编写了相应的计算程序。通过螺旋弹簧的实际可靠度计算 ,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。In this paper, the concept and operations of the blind number based on uncertained theory are introduced, and its stress strength reliable computing model is built up. What's more, the corresponding diagrams in LabVIEW language are given. The effectiveness and practicability of this computing algorithm are validated perfectly by comparing the result computed by this model with those by traditional reliability designing methods.
