| 摘 要： | 涡轴发动机数控系统传感器故障诊断需机载的发动机数学模型,由于缺乏部件特性数据,根据某型发动机地面试车稳态数据和动态数据,建立涡轴发动机慢车以上状态简化数学模型。该模型具有较好的实时性,稳态模型采用插值算法,动态模型针对不同参数分别采用动态系数法和转子动力学方法。数值仿真结果表明：该简化模型具有较高的动态和稳态精度,可以满足传感器故障诊断的需求。

| Abstract: | The simplified above-idle mathematic model of turboshaft engine was developed based on steady and transient engine ground test data because buliding an accurate on-board mathematics model for sensor fault diagnostics of aeroengine digital control system was quite difficult due to lack of detailed component characteristics. The interpolated algorithm, a transient coefficient method and rotor dynamics formula were used for the modeling, which makes the model support real-time simulation. Both steady operation and transient operation of the engine are simulated. The results show that the model has a satisfying precision, and can meet the demands of sensor fault diagnostics of aeroengine digital control system. |
