| 摘 要： | 选取Mooney-Rivlin、YEOH和Ogden三种超弹性本构模型,以橡胶材料基本力学实验数据为基础,识别出三种本构模型的参数。建立汽车悬架橡胶衬套有限元模型,以三种本构模型设置材料属性,计算了橡胶衬套轴向、径向和扭转三个方向的静态力学特性。结果表明,在小变形范围内,YEOH对橡胶衬套轴向变形仿真效果较好,Mooney-Rivlin模型对径向和扭转变形仿真效果较好。

| Abstract: | Using hyperelastic constitutive models of Mooney-Rivlin,YEOH and Ogden,with the mechanic experiment data of rubber material,the parameters of the 3 models are calculated.A finite element model of rubber bushing in a vehicle suspen-sion system is built and its material characteristics are determined by the parameters of constitutive model.So the axial,radi-cal and torsional static mechanic characteristics of rubber bushing are obtained.It＆#39;s shown that the constitutive model YEOH has the best simulation accuracy in axial deformation of the rubber bushing,with the Mooney-Rivlin excellent in radical and the torsional deformation. |
