| 摘 要： | 以航空发动机为研究对象，利用发动机测量参数变化评估发动机综合性能。将多个测量参数通过模糊信息熵方法转化成1维参数，克服了1个参数不能全面反映发动机性能的缺点；结合性能退化可靠性理论和随机过程方法，通过分析发动机性能退化过程，运用威布尔分布建立了基于随机过程的性能退化过程中的发动机性能可靠性模型。结果表明：通过模糊信息熵方法得到的性能参数能较好地反映发动机性能状况及可靠性程度。 |

| Abstract: | Taking aeroengine as research object,the aeroengine synthetic performance was evaluated using the variation of measured parameter.Many measured parameters was transformed into one dimensional parameter by fuzzy information entropy method,the weakness of one parameter that cannot completely reflect engine performance was overcame.The reliability model of the engine performance during deterioratoin process was established based on stochastic progress and using Weibull distribution,combined with performance de... |
