| 摘 要： | 通过对圆环形金属丝网橡胶成型制造过程的分析，在圆环嵌套模型基础上，结合干摩擦非线性理论和小曲梁模型建立了金属丝网橡胶材料的非线性本构关系，对不同相对密度的金属丝网橡胶试件进行了静态压缩实验，通过实验数据确定了本构关系方程的各项系数并实验结果进行比较.研究结果表明:建立的本构关系模型可以很好地描述金属丝网橡胶的非线性力学特性，实验结果能够较好地符合理论结果，并且该模型反映了相对密度、网格大小和网格宽度等参数的影响，从而实现了对材料结构刚度的预估.

| Abstract: | Through analysis of the manufacturing process of the ring metal-net rubber and on the basis of the ring nesting model, in combination with nonlinear theory of dry friction and small curving beam model, the nonlinear constitutive relation of metal-net rubber was constructed, several metal-net rubber components of different relative density were taken on the compression experiment, and the experimental data were used to determine the coefficients on constitutive relation equation and compared with the experimental results. The results show that the model of the stiffness from nonlinear constitutive relation can correctly describe the nonlinear mechanical properties of metal-net rubber, and the theoretic calculations are consistent with the experimental data. The model can reflect the influences of the relative density, mesh size, mesh width and other such parameters, providing a theoretical basis for better design and application of metal-net rubber. |
