摘要
以压气机叶片为可靠性分析对象，给出了其失效的模糊定义和模糊可靠性数学模型．用常规可靠性计算方法和本模型分别计算了压气机叶片的可靠度．结果表明，模糊可靠性方法更加合理．
The conventinal research on reliability is based on the theory of probability and represent the stochasticity of failures, but the fuzziness of failures is ignored. The definition and fuzzy reliability mathematical model of failures to analysis the compressor blade is presented. Both the conventinal reliability method and fuzzy one are presented to compute the reliability of compressor blade. The results indicate that the fuzzy reliability method is more reasonable than the conventinal reliability method.
