摘要
航空发动机涡轮转子处于高温高压的工作环境,这类零部件单纯从设计可靠性角度来考虑具有较大的局限性,比如无法量化评估实际使用环境下的涡轮转子的可靠性情况。建立了考虑工作环境因素的涡轮转子磨损模型,结合模糊数学模糊集与隶属函数的理论提出了评估随时间变化的对涡轮转子进行模糊可靠性分析与计算所依据的模糊可靠性数学模型。通过量化分析涡轮转子磨损量的影响因素确定了相应的隶属函数,利用该模糊可靠性模型实现计算基于时间的涡轮转子磨损的模糊可靠度。
An aeroengine works tinder the environment of high-pressure and high-temperature,the consideration of its component only from design reliability has great limitations.A wear model for turbine rotor con- sidering working environment factors is built,making the mathematical model of the fuzzy reliability for analysis and calculation of the fuzzy reliability of the turbine rotor. Based on the fuzzy math and fuzzy sets membership func- tion theory, the related information of the turbine rotor＇s wear determined the membership function is analyzed, and the fuzzy reliability theory is used to calculate the fllzzy reliability of turbine rotor＇s wear based on time.
