摘要
磁流变弹性体在变刚度变阻尼的隔振或吸振系统中具有广阔的应用前景,材料厚度是影响结构优化和减振效果的重要因素。为了研究材料厚度对磁流变弹性体力学性能影响,制备了同一组分不同厚度的4种试样,采用流变仪对磁流变弹性体在不同磁场、应变、频率下的动态力学性能进行表征。通过对测试结果的处理与分析,得到了磁流变弹性体材料厚度与力学性能之间的变化关系,为磁流变弹性体装置的优化设计提供依据。
MRE has been successfully applied to the variable stiffness vibration isolation and vibration absorption device, the thickness of MRE is one of the important factors affecting the device performance. In order to study influence of thickness of the sample on the mechanical properties of MRE, four samples were prepared with dif- ferent thicknesses. The dynamic mechanical properties of MRE were characterized by rheometer under different magnetic field, strain amplitude and frequency. The relationship between the thickness and mechanical proper- ties of MRE samples was obtained through processing and analysis of test results. This study can providea reference for the optimal design of MRE device.
