摘要: 提出了一种新的发动机优化调整方法.这一方法以多自由度多目标优化理论为基础,利用发动机性能仿真模型和故障诊断模型,在对故障发动机进行故障诊断的基础上,通过调整发动机可调部件以使发动机的性能达到设计要求.利用这一方法建立的发动机调整模型被用于某型处于生产试验阶段的涡扇发动机的实际试车调整中,实践表明,发动机调整模型所得到的最优调整方案能够有效地指导故障发动机的试车调整.Abstract: A new optimal adjustment method of engine was discussed. Based on multi variables and multi objectives, this method can search out an optimal adjustment case to meet the design demand in use of the engine characteristic simulation model and the result of fault diagnosis. An engine adjustment model was build up and used to a turbofan engine in the state of test. The investigation shows that the optimal adjustment case can guide the adjustment of fault engine in the trial center.
