应用流固耦合和有限元理论,通过ABAQUS软件仿真分析附加气室容积和节流口直径变化对带附加气室空气弹簧弹性力学特性的影响。结果表明:在一定范围内附加气室容积和节流口直径变化对空气弹簧的垂直刚度有明显的影响。
The influence of the volume of auxiliary chamber and orifice diameter on the mechanical properties of air spring was analyzed using fluid-solid coupling and finite element theories by ABAQUS software. The results showed that change of auxiliary chamber volume and orifice diameter influenced the vertical stiffness of the air spring significantly in a certain range.
