With the rapid development of the aviation industry, the utilization rate of a runway is getting higher and higher, and the time that aircrafts use the runway for takeoff and landing is getting less and less. Accidents are prone to occur at this stage, so the wheel brake system that plays a key role at this stage attracts much attention. The safety of the wheel brake system is important to ensure the normal takeoff and landing of aircrafts, minimize the occurrence of brake accidents and ensure the safety of the occupants and aircrafts. However, domestic research on wheel brake system mostly focuses on system design and performance simulation. There is little research on condition monitoring and health assessment of wheel brake system, especially hydraulic brake system. Therefore, based on the analysis of the working principle and flight recording parameters of the wheel brake system, the hysteresis characteristics of the system are found for the first time. The model of the wheel brake system considering the hysteresis characteristics is constructed, a health monitoring method based on Kalman filter is established. The effectiveness of the proposed method is verified by simulation and flight record data.
