摘要
针对飞机起落架的动态载荷导致液压收放系统发生功能失效的问题,在飞机起落架液压收放系统结构和动力学模型的基础上,采用基于模型和故障响应动态观测器的方法对飞机起落架液压收放系统进行故障诊断,并在飞机起落架液压收放系统故障管理实验台架上进行故障模拟,试验结果验证了故障诊断方法的准确性以及故障响应的鲁棒性。
Aiming at the problem that the dynamic load of the aircraft landing gear causes the function failure of the hydraulic retraction and release system,based on the structure and dynamic model of the aircraft landing gear hydraulic retraction and release system,the fault diagnosis of the aircraft landing gear hydraulic retraction and release system is carried out by using the model-based and fault response dynamic observer method,and the fault management experiment platform of the aircraft landing gear hydraulic retraction and release system is established The test results verify the accuracy of the fault diagnosis method and the robustness of the fault response.
