摘　　要：液压反推作动系统的同步作动是保证反推装置正常展开/收起的关键功能之一。针对节流同步与机械同步两种同步方式,依据其工作原理建立系统同步作动数学模型及系统仿真模型,通过实验验证仿真模型的有效性。根据实验边界条件设定仿真参数,研究节流阀开口尺寸、作动器传动比和同步软轴刚度对同步特性的影响,对比分析了节流同步和机械同步的差异性。结果表明,系统中节流阀开口尺寸、作动器传动比和同步软轴刚度对系统的影响均具有非线性规律;在相同载荷条件下,机械同步精度比节流同步精度提高68%;仿真模型能够模拟系统运动过程中的同步性变化规律,可作为液压反推作动系统同步性研究的有效工具。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 stffness 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.
