这项工作描述了金属橡胶颗粒（MRP）阻尼器设计的基础上拉胀（负泊松比）细胞配置的机械性能。拉胀阻尼器配置由反四手性蜂窝构成，其中圆柱体填充有MRP材料。MRP样品已经经受准静态负载以从静态滞后曲线测量刚度和损耗因子。进行了参数实验分析，以研究相对密度和填充率对MRP静态性能的影响，并确定MRP装置最佳使用的设计指南。通过静态和动态力响应技术，提供了一个实验评估的集成的拉胀MRP阻尼器的概念。
The work describes the mechanical performance of a metal rubber particles (MRP) damper design based on an auxetic (negative Poisson's ratio) cellular configuration. The auxetic damper configuration is constituted by an anti-tetrachiral honeycomb, where the cylinders are filled with the MRP material. The MRP samples have been subjected to quasi-static loading to measure the stiffness and loss factor from the static hysteresis curve. A parametric experimental analysis has been carried out to investigate the effect of relative density and filling percentage on the static performance of the MRP, and to identify design guidelines for best use of MRP devices. An experimental assessment of the integrated auxetic-MRP damper concept has been provided through static and dynamic force response techniques.
