摘　　要：通过非线性有限元分析软件建立了空气弹簧联轴器模型,分别利用Rebar单元和Herrmann单元模拟帘线以及气胎胶囊,从而实现对刚度特性的计算。本文分析比较了影响空气弹簧径向刚度及轴向刚度的多种因素,包括结构形式(如气囊对数、气囊容积、气囊高度、气囊有效直径)、气囊帘线材质、帘线层数、帘线的角度、橡胶的材料特性以及气囊初始充气压力等。通过有限元仿真设计方法,对几种影响空气弹簧刚度特性的因素进行了优化,从而确定空气弹簧联轴器的参数。本文不但得到了各参数影响联轴器刚度的趋势,而且得到了各参数下联轴器的刚度值。A model is established with non-linear finite element analysis software MSC.MARC based on rebar element and Herrmann element to simulate cord and tire rubber and the rigidity of air spring coupling is calculated.The parameters of air spring coupling is optimized through to analysis the effects of structure style（such as gasbag number,gasbag height,gasbag actual diameter）,cord material,cord layers,cord angle,rubber material,pressure in gasbag,and so on.On the radial rigidity and the axial rigidity.By calculating and studying its radial rigidity and axial rigidity,the paper not only conduct the quantitative analysis for the influences of various parameters,but also obtain basically radial rigidity values and axial rigidity values of air spring coupling under various parameters accurately.
