摘　　要：以某型航空发动机为研究对象,建立其润滑供油系统数学模型。利用Matlab编程计算得出系统在不同转速、不同温度下各润滑点滑油流量、滑油压力等性能参数数据。重点分析了不同温度下,系统增压级流量、压力的变化趋势。研究结果为发动机润滑系统的设计和故障诊断提供参考。The mathematical model of lubrication oil supply system is established for an aeroengine. The performance parameters with different rotational speeds and temperatures on lubrication points, including the flux and pressure of lubrication, are calculated with MATLAB. The variability characteristics of flux and pressure of structures are mainly analyzed in this paper. Research results will provide a profound reference value for the design of oil supply system of engines.
