中文摘要：
magnetorheological 的一个好机械模型更潮湿(MRD ) 是必要的在数字模拟预言 MRD 的吃惊隔离表演。但是目前， MRD 的机械模型都从受到泛音颤动负担的实验被导出。在这份报纸，主公司生产的商业 MRD (类型 RD-1005-3 ) 试验性地被学习以便在影响负担下面调查它的隔离表演。MRD 的一个新机械模型根据影响测试获得的数据被建议。在数字结果和测试数据之间的一个好协议被观察，它证明模型好在影响负担下面模仿 MRD 的动态性质。MRD 能在影响负担下面显然改进加速和结构的排水量反应，这也被表明。
英文摘要：
A good mechanical model of magnetorheological damper （MRD） is essential to predict the shock isolation performance of MRD in numerical simulation. But at present, the mechanical models of MRD were all derived from the experiment subjected to harmonic vibration loads. In this paper, a commercial MRD （type RD-1005-3） manufactured by Lord Corporation was studied ex- perimentally in order to investigate its isolation performance under the impact loads. A new me- chanical model of MRD was proposed according to the data obtained by impact test. A good agreement between the numerical results and test data was observed, which showed that the model was good to simulate the dynamic properties of MRD under impact loads. It is also demon- strated that MRD can improve the acceleration and displacement response of the structure obvi- ously under impact loads.
