| 摘 要： | 基于部件法建立了某辅助动力装置的数学模型,硬件在回路(HIL)仿真试验器上验证了建模方法的正确性和数学模型精度。在此基础上,采用故障注入的方法修改数学模型。在HIL仿真试验器上再现了APU试验时出现的故障现象。通过分析找出了故障原因,为排故工作的开展提供了正确的指导。

| Abstract: | A mathematical model is presented based on components methods in this paper. The validity and accuracy of the model is validated via HIL(hardware in Loop) simulation rig. Fault injection is utilized to modify the model and the fault which happened during APU test is duplicated. Thus, the cause of fault is isolated and a reliable guide is suggested for the APU trouble shooting. |
