摘要

通过对编织-嵌槽型金属橡胶的细观结构进行简化,将其等效成了线圈以串并联形式连接而成的组合系统。依据刚度-变形曲线的特点,将构件的压缩变形过程分为了线性阶段、非线性阶段及高次非线性阶段,建立了对应的本构模型。该模型包含了丝径、弹性模量、丝材密度等基本工艺参数,从理论上解释了编织-嵌槽型金属橡胶力学特性的物理本质。通过试验数据与理论计算结果的对比对模型进行了验证,结果表明该模型能够较好地表征编织-嵌槽型金属橡胶的力学行为。为材料力学特性的进一步研究以及指导材料的设计提供了理论依据。

Abstract

By simplifying the microstructure, knitteddapped metal rubber material was equivalent to a composite system assembled by loops in seriesparallel form. According to the characteristics of the stiffnessdeformation curve, the compression deformation process was divided into three phases including linear phase, nonlinear phase, and highorder nonlinear phase. Constitutive models were established and mathematical expressions for stiffness and compressive load were deduced. The models containing the basic technics parameters, such as metal wire diameter, elastic modulus, wire density could explain the physical nature of mechanical characteristics of knitteddapped metal rubber. The models were validated by the comparison of experimental data and calculated results. The result showed that the models were valuable for the analysis of the mechanical behaviors of knitted dapped metal rubber. It provides theoretical support for further studying mechanical characteristics and guiding design of the material.
