摘要: 联合发动机循环模拟与标定技术建立小型活塞航空发动机动力性和经济性的多目标优化模型。对校验后的BOOST模型进行DOE(Design of Experiment)正交试验,对试验数据进行统计数学建模,并对局部模型误差进行控制,进行响应面模型分析,通过MBC(Model-Based Calibration)工具箱进行优化标定, 选用经济适用的NBI(Normal Boundary Intersection)进行多目标优化.给出了优化的点火提前角、喷油量的MAP图,优化参数对扭矩和燃油消耗等目标的响应面模型,对提升小型航空发动机性能有重要的参考价值.

Abstract: Multiobjective optimization model of aero-engine torque and fuel economy was established in Boost and Matlab environment. The progress of the calibration was elaborated, including building Boost model, design of experiment(DOE)tests, mathematical statistical modeling ,the response surface of variables was explored to the relationship between the objectives and variables, the statistical modeling can control errors. The model-based calibration(MBC) toolbox was applied to optimize the model, the method of normal boundary intersection is economical and applicable to deal with multiobjective optimization of calibration. The map of ignition timing and the amount of injection fuel in each cycle were given, the relationship between the target variables and independent variables was given with response surface map, which are useful to improve the performance of aero-engine.
