摘要
Abstract
The synchronization operation of the hydraulic thrust reverser actuation system is one of the key functions to ensure the normal deployment/retraction of the thrust reverser device.Based on the working principles of throttling synchronization and mechanical synchronization,establish a mathematical model and system simulation model for system synchronization,and verify the effectiveness of the system synchronization simulation model through experiments.Based on the experimental boundary conditions,simulation parameters are set to study the effects of throttle valve opening size,actuator transmission ratio,and synchronous soft shaft stiffness on synchronization characteristics.The differences between throttle synchronization and mechanical synchronization are compared and analyzed.The results indicate that the throttle valve opening size,actuator transmission ratio,and synchronous soft shaft stiffness all have nonlinear effects on the system.Under the same load conditions,the mechanical synchronization accuracy is 68%higher than the throttling synchronization accuracy.The simulation model can simulate the synchronization changes during the system motion process,and can serve as an effective tool for studying the synchronization of hydraulic thrust reverser actuation system.关键词
