摘　　要：液压系统作为航空装备的核心系统,其运行状态直接关系到装备的安全。为掌握航空液压系统故障演化规律,实现液压系统故障的诊断和隔离,在液压系统FMECA分析的基础上,确立需研究的液压系统故障模式及相对应的关键征兆参数,明确传感器布局优化过程中约束条件和布局方案,采用混合整数非线性规划(MINLP)模型描述其传感器布局优化问题,并采用枚举法求解该模型获得传感器布局的优化结果,优化后的方案可满足设计要求,达到了优化的目的,从而证明了MINLP方法和模型的有效性和实用性。基于MINLP方法的传感器优化布局技术可使液压系统监测系统整体布局更加合理、可靠,提升系统的测试性和可靠性,为实现液压系统PHM提供技术支撑。As the core system of aviation equipment,the hydraulic system is directly related to the safety of equipment. In order to grasp the evolution law of aero-hydraulic system failures and realize the diagnosis and isolation of hydraulic system failures,based on the FMECA analysis of hydraulic system,the hydraulic system failure modes and corresponding key symptom parameters are established, and the constraints and layout schemes during the sensor layout optimization are clarified. The mixed-integer non-linear programming( MINLP) model was used to describe the optimization of the sensor layout,and the enumeration method was used to solve the model to obtain the sensor layout optimization results. The optimized solution of the hydraulic system sensor layout can meet the design requirements and achieve the purpose of optimization,thus the validity and practicability of the MINLP method and model are proved. The sensor optimized layout technology based on the MINLP method can make the overall layout of the hydraulic system monitoring system more reasonable and reliable,improve the testability and reliability of the system,and provide technical support for the realization of the PHM of the hydraulic system.
