摘要
通过对橡胶材料试件的单轴拉伸的应力-应变曲线的实验,利用最小二乘法对4种橡胶超弹性本构模型参数进行拟合,对比了不同模型的拟合精度。以汽车前悬架橡胶支座为例,计算了其中3种本构模型参数的力-位移结果,并与实验数据进行比较,结果表明:仅有单轴拉伸的应力应变情况下,Ogden模型对该橡胶的拟合精度最高;超弹性本构模型参数对于橡胶件的力-位移仿真结果的趋势基本一致。
Through the experiment of the stress-strain curve of the rubber material specimen in uniaxial tension,the least square method is used to fit the parameters of the four rubber superelastic constitutive models,and the fitting accuracy of different models is compared.Taking the rubber bearing of the automobile front suspension as an example,the force-displacement results of the three constitutive model parameters are calculated and compared with the experimental data.The results show that the Ogden model is only under uniaxial tension stress and strain.The fitting accuracy of the rubber is the highest,the trend of the superelastic constitutive model parameters for the force-displacement simulation results of the rubber is basically the same.
