摘要 对空气弹簧的几何、橡胶材料、状态及气固耦合等非线性问题进行了理论分析,阐释了在有限元分析中的计算依据。建立空气弹簧的理论及数值分析模型,采用非线性分析软件对其垂向静态力-位移特性进行了计算分析。计算值与试验结果误差小于10%,验证了计算方法的精确性。分析了设计参数——橡胶皮囊压力、帘线角、帘线间距和帘线层数等对空气弹簧承载能力的影响。为空气弹簧弹性静特性力-位移性能的前期概念设计提供参考。 The vertical static stiffness problem of vehi~.le suspension air spring finite element model has been established,and the nonlinearity of geometry, and state,the material,as well as the air-solid coupling,are all analyzed theoretically. The vertical static models characteristics are analyzed which is powerful in nonlinearity. The analysis results show that the simulation model validated through comparing with experimental data. Parameters influeneing static vertical stiffness of the spring such as pressure,cord an- gle,distance between cord as well as layers of the fiber layer are analyzed. The proposed modelling and analysis methods in the guidance of the air spring prototype design were proposed.
