摘　　要：为了解决农用拖拉机复杂工况下的减振问题,设计了一种应用于拖拉机前桥悬架上的带有2个可调节流孔和蓄能器的油气悬架系统。利用AMESim软件建立油气悬架的仿真模型,仿真研究了节流阀孔径、激励频率、蓄能器压力和体积等参数变化对油气悬架输出力特性的影响。结果表明,所设计的油气悬架系统具有良好的非线性输出力及速度特性,可通过调节节流阀孔径调节其阻尼力并获得较好的输出力与位移关系,为农用车辆的油气悬架系统设计及控制提供一定理论参考。In order to solve the vibration reduction problem of agricultural tractor under complex working conditions,a pneumatic suspension system with two adjustable flow holes and an accumulator was designed for the front axle suspension of the tractor.AMESim was used to propose the simulation model of the pneumatic suspension,and the influences of throttle aperture,excitation frequency,accumulator pressure and volume on the output force characteristics of the pneumatic suspension were studied.The simulation results showed that the designed oil-gas suspension system has good nonlinear output force and velocity characteristics.The damping force of the suspension could be adjusted by adjusting the diameter of the throttle valve,and a better relationship between output force and displacement could be obtained.Some references were provided for the future design of the oil-gas suspension of agricultural vehicles.
