空气弹簧帘线参数对刚度特性影响的显著性
|
摘要
基于某重卡车用悬架空气弹簧,针对其材料、几何、接触、气固耦合等非线性力学特性,采用Abaqus软件建立空气弹簧的有限元模型,对其垂向静态力学特性进行仿真分析,并采用正交实验法分析帘线材料、帘线布置角度、帘线网格间距、帘线横截面积和帘线层数对其垂向刚度的影响。结果表明:帘线材料及结构参数对空气弹簧的垂向刚度有很大的影响,其中帘线布置角对空气弹簧的垂向刚度影响最显著,帘线截面面积和帘线层数对其刚度影响一般,帘线弹性模量和帘线间距对其刚度影响较小。
This study is made based on the fact that the air springs are installed in heavy trucks,as to the non-linear mechanical properties such as material,geometry,contact and gas-solid coupling,the finite element model is established by Abaqus software and the vertical mechanical characteristics are analyzed from it.Orthogonal experiment method is used to analyzed the effect on the vertical stiffness of air springs made by the following five factors cord material,cord arrangement angle,cord grid spacing,cross-sectional area of the cord and the number of cord layers. The research shows that the cord parameters have an obvious effect on the vertical stiffness of the air spring. And it also shows that the angle of the cord arrangement has a large influence on the vertical stiffness,both the cross-sectional area of the cord and the number of the cord layers have normal influence on it,and it is less influenced by the cord elastic modulus and cord spacing.
