| 摘 要： | 基于Sherwood-Frost本构方程，并结合材料的特点对考虑温度效应的编织-嵌槽型金属橡胶本构方程的组成及各项的表达形式进行了讨论及确定。根据准静态压缩试验得到的不同温度下编织-嵌槽型金属橡胶材料的试验数据，拟合了所构建本构方程中的参数，最后结合不同密度试件在不同温度下的试验数据，通过仿真对本构方程进行了验证。结果表明仿真结果与试验结果之间具有较好的一致性，所构建的本构方程基本可以满足对高温环境下编织-嵌槽型金属橡胶准静态本构关系的预估要求。

| Abstract: | Based on the Sherwood-Frost equation and characteristics of the material, the constituent parts and forms of the constitutive equation for the knitted-dapped metal rubber considering temperature effect are discussed. According to the quasi-static compression experimental data gained at different temperatures, the parameters for the constitutive equation are obtained by fitting. Considering the experimental data of different specimens with different densities at different temperatures, numerical simulations are conducted to validate the constitutive equation. The results show that the simulation results are in good agreement with the experimental results. The obtained constitutive equation can satisfy the requirements for estimation of the quasi-static compression constitutive relation of the knitted-dapped metal rubber at high temperature. |
