摘　　要：基于多支路互连式油气悬架刚度阻尼耦合特性,对同一行程阻尼非一致性问题进行了研究。在对该油气悬架连通结构形式及原理分析的基础上,建立了液压系统中阻尼阀、蓄能器及部分液压系统数学模型。通过软件仿真,观察比较了系统特性的变化,找出了同行程阻尼非一致性产生的原因,并分析了参数变化对同行程阻尼非一致性的影响。研究结果对互连式油气悬架阻尼半主动控制研究具有指引参考价值。A research about damping non-coincidence in same stroke had been done based on coupling characteristics of stiffness and damping of multi-branch interconnected hydro-pneumatic suspension. The mathematical model of main damping valves, accumulators and partial hydraulic system were developed based on penetrating analysis of structure and principle of interconnected hydro-pneumatic suspension. The real reason which caused the And the impact of parameters problem of damping non-coincidence was find out by means of simulation to damping non-coincidence is analyzed, which has reference value for it.
