基于金属橡胶内部微元螺旋卷结构，并以弹簧理论建立其力学模型，分析了在螺旋卷之间不同接触（“未接触、滑动、压缩”）形式下的刚度公式并解释载荷作用下刚度曲线不同阶段的特性。基于金属橡胶的非线性对阻尼进行计算，通过试验研究金属橡胶构件的密度、厚度对静态刚度曲线不同阶段的影响，及在不同振幅、频率下比阻尼随密度和厚度的变化规律，为金属橡胶的设计及工程应用有重要的指导意义。
Abstract
Based on the wire helix structure and the principle of micro helical spring in the metal rubber（MR）cell geometry,a mechanical model was established.The stiffness formula was analyzed under different contacts (non-contact,sliding,compression) of the wire helix.The characteristics of different stages of the stiffness curve under the load were explained.The damping coefficient was calculated by the MR nonlinearity.The effect of density and thickness of metal rubber components on different stages of static stiffness curve was studied by experiments，and the damping coefficient was discussed under different amplitude and frequency.The experiment study can provide a reference to the design of metal rubber and its applications in engineering.
