摘要
本文针对含增粘剂润滑油的流变特性,将线性多组元粘弹性模型在特殊的共转坐标系下推广,得到了能同时反映含增粘剂润滑油剪切稀化及其粘弹性的本构方程.将该本构关系给出的表现粘度与实验结果进行了对比,证明该本构关系能够较全面反映含增粘剂润滑油的流变特性且形式简单便于工程应用.
Based on the analysis of the experimental data, a nan - linear viscoelastic constitutive equation is deduced iv a special co - rotational coordinates. This equation can reflect both the shear thinning and the viscoelastic properties of the lubricant with VI additive.There is a good agreement between the prediction of the equation and the experimental data.This constitutive poocesses a simple form, so it is suitable for engineering application.
