摘要
在分析油气悬挂系统结构及基本工作原理的基础上,对双气室油气悬挂缸主要参数进行计算,并建立其数学模型。基于AMESim软件建立了油气悬挂的仿真模型,分析了悬挂缸阻尼孔径、蓄能器初始压力和初始体积对油气悬挂输出特性的影响,结果表明:悬挂缸阻尼孔径对阻尼特性影响较大,而蓄能器初始压力和体积是影响悬挂系统刚度的主要因素。仿真结果对油气悬挂系统的设计及相关参数的选用具有参考价值。
On the basis of the analysis of basic working principle and structure of hydro-pneumatic suspension,the main parameters of its cylinder were calculated,and the mathematical model of the dual air chamber hydro-pneumatic suspension was created. A simulation model of the suspension was built by means of the AMESim software,the influence of the diameter of damping holes of cylinder、the initial pressure and initial volume of the accumulators on the output characteristic of hydro-pneumatic suspension was discussed. The results show the diameter of damping holes have a greater impact on the damping characteristics of hydro-pneumatic suspension,and the initial pressure and initial volume of the accumulators are essential for influencing the rigidy of suspension. The simulation results have a reference value on the design and selection of the parameters of the hydro-pneumatic suspension system.
