对单个双气室油气悬挂系统进行建模与仿真分析,构建了连通式和非独立式油气悬挂系统的虚拟样机模型及车辆侧倾特性的虚拟试验平台,研究了连通式及非独立式这2类油气悬挂类型对多轴转向车辆侧倾特性影响的规律。仿真分析结果表明,非独立式油气悬挂系统的侧倾刚度比连通式油气悬挂系统大。该研究成果可为改进油气悬挂系统的设计及提高车辆操纵稳定性提供参考依据。
對單箇雙氣室油氣懸掛繫統進行建模與倣真分析,構建瞭連通式和非獨立式油氣懸掛繫統的虛擬樣機模型及車輛側傾特性的虛擬試驗平檯,研究瞭連通式及非獨立式這2類油氣懸掛類型對多軸轉嚮車輛側傾特性影響的規律。倣真分析結果錶明,非獨立式油氣懸掛繫統的側傾剛度比連通式油氣懸掛繫統大。該研究成果可為改進油氣懸掛繫統的設計及提高車輛操縱穩定性提供參攷依據。

Based on the modeling and simulation study of the system of twin-accumulator hydro-pneumatic suspension（HPS）,the virtual prototype of the dependent and linked hydro-pneumatic suspension and the virtual test platform of vehicle roll over characteristic were built,the effects of the dependent and linked hydro-pneumatic suspension on the vehicle roll over characteristic were analyzed.It discovered from emulation analysis that the stiffness characteristics of the dependent HPS would be higher than the linked HPS.The results of this research provided references for the design of HPS and for the improving of the maneuvering stability.
