摘　　要：针对飞机液压系统的实际使用工况难以评价的难题,提出一种基于非对称贴近度的多级模糊综合评判方法。首先通过分析飞机液压系统实际使用工况,建立了基于非对称贴近度的飞机液压系统使用工况模糊综合评判模型,并应用于某型飞机液压系统实际使用工况的评价中。该研究方法不仅可以解决某一液压系统在某一使用工况下的使用可靠性的评价问题,而且还可以解决同一液压系统在不同使用工况下的使用可靠性评价问题。Aiming at the assessment problem of actual operational conditions for aircraft hydraulic system, a method of multilevel fuzzy comprehensive evaluation based on asymmetric degree is proposed. Firstly, the actual operational conditions of aircraft hydraulic system are analyzed. Then the fuzzy comprehensive evalu- ation model of operational conditions for aircraft hydraulic system is established. Finally, the method is used to evaluate the actual operational conditions for one aircraft hydraulic system. The research method not only can solve the operational reliability evaluation problem of a certain aircraft hydraulic system under a certain operational condition, but also can solve the operational reliability evaluation problem of the aircraft hydrau- lic system under different operational condition.
