Modeling under coupling stress is challenge in the field of fault prediction and health management. Based on the the ground degradation test of the oxygen concentrator, this research proposes a modeling framework with partial differential equations combining mechanism model and data driven model, which addresses the linear correlation of two stresses during the test and their coupling effect on the degradation. Based on the analysis of degradation mechanism of the basic form, data driven method is used to determine the specific parameter of partial differential equations. Then, the two stresses are decoupled based on the equations. Results show that the increase in the bleed air moisture content raises the degradation rate of the oxygen concentrator. Furthermore, as the oxygen concentrator performance degrades, the sensitivity of the oxygen partial pressure on the bleed air pressure is reduced. Therefore, the slope factor of the oxygen partial pressure to bleed air pressure is determined as the health indicator. The pattern recognition of Kalman filter shows that the oxygen concentrator degradation can be divided into stationary and degradation stages, which is verified by comparison with the degradation data of the oxygen concentrator in the actual service environment.
