摘　　要：介绍重型汽车油气悬架的结构与工作原理,推导油气悬架阻尼特性的数学模型。利用AMESim仿真软件建立油气悬架的仿真模型,研究油气悬架阻尼孔直径的大小对重型汽车行驶平顺性和稳定性的影响。仿真结果表明,较小的阻尼孔直径有利于提升重型汽车行驶的稳定性,较大的阻尼孔直径有利于提升重型汽车行驶的平顺性。在设计油气悬架阻尼孔时,应根据重型汽车具体的行驶条件来综合考虑,设计适合的阻尼孔直径。The structure and working principle of hydro pneumatic suspension of heavy vehicle are introduced,and the mathematical model of the damping characteristics of hydro pneumatic suspension is deduced.On this basis,the simulation model of hydro pneumatic suspension is established by AMESim simulation software,and the influence of the diameter of hydro pneumatic suspension damping hole on the ride comfort and stability of heavy vehicles is studied.The research shows that smaller diameter of damping hole is conducive to improving the driving stability of heavy vehicles,and larger diameter of damping hole is conducive to improving ride comfort of heavy vehicles.When designing the damping hole of hydro pneumatic suspension,the appropriate diameter of damping hole should be designed according to the specific driving conditions of heavy vehicles.
