“…Using deep learning and other methods to determine the relationships between input and output data, system operation prediction, as well as fault diagnosis and analysis can be achieved. Deep learning is used in some studies to investigate the degradation failure of EHA [7,8]. Li et al [9] proposed a fault tree method for hydraulic systems failure analysis in case of incomplete data.…”

In this paper, a new degradation model of the more electrical aircraft (MEA) actuation system is proposed. The bond graph model is used to build the dissimilar redundancy actuation system model, taking into account the degradation behavior (wear, fatigue, aging) of components in the system operation and the fault coupling phenomenon caused by the accumulation of dissipated energy in space and time, and a fault coupling degradation model of the actuation system is established with clear mechanism support. Through the fault mechanism analysis, various fault types are injected into the bond graph model of the actuation system, and the simulation results are compared. The influence of fault propagation on system output is analyzed, the system’s reliability is assessed, and the performance evaluation of the actuation system is realized while taking the fault coupling mechanism into account.

“…The speed- change, reversing, and shock-absorption functions of the vehicles are all performed by the transmission. 1 The transmission is as important as the engine. With the development of vehicles toward higher speeds and power, an increasing number of vehicles use hydraulic wet clutches to shift gears.…”

“…4 With the development of vehicle technology in the context of Industry 4.0, a shifting quality was proposed to examine the performance of shift systems. 5 Detrimental torque shock is unavoidable when a vehicle is shifting gears. The impacts can make the occupants physically uncomfortable and can affect the fatigue lives of the vehicle components.…”

Focusing on the problems of weak anti-pollution capability and large lateral sliding friction of gears in traditional vehicle cushion valves, this study combined two-dimensional (2D) technology and the concept of pressure torsion transmission and proposed a 2D buffer valve with a fast response, high precision, and strong anti-pollution capability. The structure and working principle of the 2D buffer valve were introduced, and a dynamic model was developed for the 2D buffer valve. The model was jointly solved by Simulink and AMESim, and simulation analyses and experimental research were performed. The research results show that the step response time of the 2D pressure torque transmission buffer valve was approximately 0.024 s, and the maximum overshoot was approximately 7.4%. During the shift buffering process, the maximum deviation was 0.077 MPa, and the steady-state error was 0.018 MPa. The buffer valve proposed in this paper could achieve good control of the clutch oil pressure of the vehicle transmission, thereby improving the buffering performance and shifting quality in heavy-duty vehicles.
