编织-嵌槽型金属橡胶是一种新型弹性阻尼材料。为了研究该种材料的压缩性能，对其进行了压缩试验，并从细观角度对试验结果进行了分析。提取了结构单元模型，建立了构件的本构关系模型，并通过计算结果与试验数据的比较对本构关系模型进行了验证。结果表明：编织-嵌槽型金属橡胶构件的压缩变形分为线性阶段和硬化阶段两个特征阶段；金属丝之间的摩擦系数、线圈的几何参数等因素都会对编织-嵌槽型金属橡胶构件的刚度产生影响；建立的本构关系模型可以较好地描述材料的载荷-位移关系。

Knitted-dapped metal rubber is a new kind of non-linear material.The compression mechanism of knitted-dapped metal rubber was investigated and its compressive performances were tested.The test result was analyzed in the microcosmic aspect.Structure units were abstracted.A constitutive relation model for the construction member was established and it was proved to be correct by the comparison of calculated result and test data.The results show that the knitted-dapped metal rubber’s compressive deformation has two phases,i.e.,the linear stage and hardening stage.Many factors,such as the friction coefficient and metal coils’geometric parameters,can influence the stiffness of the construction member.And the description for the relationship between the material’s force and displacement by using the constitutive relation model is satisfactory.
