摘要
要确定橡胶制品在外部因素作用下的力学响应,就需要建立起能够精确描述橡胶材料力学性能的本构模型。通过对橡胶材料进行单轴压缩以及应力松弛实验,并与ABAQUS数值模拟相结合,建立并拟合了橡胶材料超弹-黏弹本构模型以及相关参数,同时建立了与实验条件一致的仿真模型。结果表明,实验数据与仿真数据的误差较小,验证了建立的超弹-黏弹本构模型的准确性。
In order to determine the mechanical response of rubber products under the action of external factors,it is necessary to establish a constitutive model that can accurately describe the mechanical properties of rubber materials.By using rubber material and stress relaxation of uniaxial compression test,and combining with numerical simulation of ABAQUS,the hyperelastic-viscoelastic constitutive model and related parameters are established and fitted.At the same time,the simulation model that consistent with the experimental conditions is set up.The results show that the difference between experimental data and simulation data is small.The accuracy of the hyperelastic model and viscoelastic model is verified.
