Abstract: A turbofan engine hydro-mechanical control system performs complex accelerating control law. In order to
analyze the performance of the accelerator, the co-simulation model based AMESim and Simulink was established and the
correctness of the model was verified, simulation results indicate the model has high precision. Some components’ impact on
accelerator was emphatically analyzed and the changes on acceleration characteristic by adjusting component parameter
were displayed. The conclusions of the paper provide evidence for the improvement and modification of the hydromechanical
control system.

摘要: 燃油分布器对供给发动机的燃油流量进行调节，进而改变发动机的转子转速、涡轮前温度等状态参
数，它的工作特性也影响着发动机的加速性、稳定性等性能参数。在发动机地面台架试车过程中，发动机出现了
转速下掉的故障，初步认为是燃油分布器工作不正常导致的。在对该型燃油分布器工作原理分析的基础上，利用
AMESim 软件构建相应的仿真模型，再现了工程实践中出现的发动机转速掉转的故障现象，分析并对其结构参数进
行了优化。仿真结果为排故、系统的性能了解和改善提供了技术依据，本项研究已经成功应用于工程实践。

Abstract: Fuel distributor adjusts the supply of engine fuel flow． Thereby，it affects such state parameters of the aeroengine
as rotor speed，turbine inlet total temperature，etc． and its operating characteristics also affect the engine speed，stability
and other performance parameters of aeroengine． It occurred that certain engine speed swung in the ground test bed
process． The reason for which was due to the fuel distributor not working properly in preliminary view． Based on the analysis
of working principle of this type of fuel distributor，the corresponding simulation model in the software AMESim was built to reproduce
the phenomena of engine speed swing appearing while in use，analyze the cause for faults and optimize the parameters
of its structure． The simulation results provide the technical basis for troubleshooting，understanding and improving the performance
of the system，and this study has been successfully applied to engineering practice．
