摘要
针对某型涡轴发动机燃油调节器的工作特点,对其中的重要部件——转速伺服系统进行了建模仿真研究。通过对其结构及工作原理的深入分析,得出其动、静态条件下具体的数学模型。为验证模型的正确性,在AMESim软件中搭建了转速伺服系统组件的模型;并对其进行了仿真验证。仿真结果表明,转速伺服活塞可以很好地随着顶杆位移的变化而变化,和喷嘴挡板的流通面积基本一致,满足了系统性能要求指标,对涡轴发动机的设计具有实用价值。
Based on X type turboshaft engine fuel regulator work characteristics, one of the important parts of speed servo system were modelecl and simulatel by analyzing its structure and working principle of thorough analy- sis, the dynamic, static condition the concrete mathematical model. In order to verify the correctness of the model, the speed servo system component model was built in the AMESim software. The simulation results show that, the speed servo piston can be very good with the top rod displacement and change, and the flapper nozzle flow area are basically the same, to meet the system performance requirements of turboshaft engine, the design has practical val- ue.
