| 摘 要： | 基于气体热力学和气体动力学,推导了带附加气室空气弹簧垂向刚度表达式,建立了节流孔质量流率数学模型,并在AMESim平台下建立了带附加气室空气弹簧悬架的1/4仿真模型,分析了节流孔横截面积和附加气室容积对带附加气室空气弹簧悬架动力学特性的影响。研究结果表明：节流孔横截面积是影响带附加气室空气弹簧悬架阻尼特性的关键因素,随着节流孔横截面积的增大,带附加气室空气弹簧悬架阻尼特性呈现先增大后减小的趋势；增加附加气室可以减小带附加气室空气弹簧悬架系统刚度,增大附加气室容积可以降低带附加气室空气弹簧悬架系统的自振频率,有利于改善带附加气室空气弹簧悬架系统的隔振性能。

| Abstract: | Based on the thermodynamics and kinetics of gas, with auxiliary chamber derived vertical stiffness expression, the establishment of a mass flow rate orifice mathematical model, and in AMESim platform established air suspension with additional air chamber 1 / 4 simulation model to analyze the impact of cross-sectional area of the orifice and the auxiliary chamber volume of air suspension vibration isolation characteristics. The results show that: orifice cross-sectional area is a key factor affecting air suspension with additional air chamber damping characteristics, along with an increase in cross-sectional area of the orifice, air suspension damping characteristics presented after the first increase and then decrease; adding additional chamber can reduce the stiffness of the suspension system, increasing the volume of auxiliary chamber can reduce the vibration frequency air suspension system, air suspension system will help to improve isolation performance. |
