摘　　要：针对以薄壁孔为阻尼孔的单气室油气悬架系统,对悬架缸内产生气穴的原因进行了理论分析,建立其数学模型,分析各参数对悬挂油缸产生气穴的影响,并利用仿真软件建立仿真模型。通过比较,得到仿真结果与理论分析一致,为优化单气室油气悬挂系统提供了理论依据。Based on hydro-pneumatic suspension with a thin-wall der is analyzed. The mathematic model is set up. The factors to simulation model is built by the software. The simulation results comparison. It provides a theoretical basis for optimization of the damping hole, the causation of cavitation in cylin- cause cavitation in the cylinder are analyzed. The are consistent with the theoretical analysis through hydro-pneumatic suspension with single chamber.
