摘　　要：在橡胶超弹性及黏弹性本构模型基础上,提出超-黏弹性本构模型。以某车前悬架控制臂橡胶衬套为研究对象,建立其动态特性有限元模型,并将仿真结果与试验数据对比。结合已有的橡胶衬套动态特性试验数据,采用自适应响应面法识别得到与研究对象匹配精度较高的频域黏弹性本构模型参数。建立其动态特性相应工况的有限元模型,进而得出橡胶衬套动态特性迟滞回线,求得阻尼角信息,完成橡胶衬套动态特性信息重建。A hyper-viscoelastic constitutive model of rubber is proposed based on hyperelastic and viscoelastic constitutive model. The rubber bushing of a vehicle front suspension control arm, with the finite element model is established and studied. The results of simulation is compared with test. The adaptive response surface method is adopted, with dynamic characteristic test date having been acquires, a high precision rubber parameters of the viscoelastic constitutive model are identified and obtained in frequency domain. Based on dynamic characteristic FE model, dynamic characteristic hysteresis loops of the rubber bushing are determined, and the information of damp- ing angles is also obtained. The complete dynamic characteristic information has been reconstructed.
