| 摘 要： | 为分析滑油系统特性，研究其与航空发动机协同工作及设计问题，基于滑油系统元部件的流量、压力和换热特性在MATLAB/Simulink下开发了通用仿真模块库，构建了包含供油、回油、通风和热力系统的全系统仿真模型.以某型涡扇发动机及其滑油系统为例，计算了高温起飞工况下滑油系统主要工作参数值，并与商业软件Flowmaster对比计算结果，相对误差保持在3.8%以下.利用全系统仿真模型的拓展性，成功与GasTurb发动机模型进行联合仿真，使用遗传算法优化滑油系统设计参数，通过改变供油分配比例使最高回油温度降低4.12%，可为滑油系统的设计及改进提供参考.

| Abstract: | In order to analyze the oil system's characteristics and study the coperative working and design problems involving aero-engine,a general simulation block library for its components was developed in MATLAB/Simulink based on flow rate,pressure and heat transfer characteristics.Then a full-system simulation model was established,including sup ply,return,air and thermal system.Taking a certain turbofan engine and its oil system as example,the main working parameters of the oil system were calculated under high temperature taking off condition.Compared with the calculated values of Flowmaster model,the relative error was less than 3.8％.Through the extension ability of the full-system simulation model,a co-simulation with GasTurb engine model was successfully implemented and the oil system's design parameters were optimized through genetic algorithm.The highest temperature of return oil decreased by 4.12％ by changing the oil supply ratio.This method can provided a reference for oil system design and improvement. |
