摘　　要：根据磁流变弹性体的工作模式和工作原理,设计一种舰用新型的磁流变弹性体隔振器结构,该隔振器中磁流变弹性体处于剪切压缩的状态。采用经典理论对隔振器尺寸进行计算,并应用有限元对其静、动态力学性能进行分析,并对隔振器在不同控制电流下的动态性能进行试验,结果表明,所设计的磁流变弹性体隔振器结构是合理的;随着控制电流的增大,动态刚度不断增大,当控制电流超过2 A以后,动态刚度的改变量趋于平缓;隔振器动态刚度随磁场的变化较明显,即隔振器刚度可进行有效调节。According to the working pattern and principle of magnetorheological（MR） elastomer, a new type of the ship＇ s isolator with the magnetorheological elastomer was designed. The magnetorheological elastomer works in shear and compression state. Using the classical theory, the dimensions of the isolator were calculated. The static and dynamic mechanical properties were analysed by means of finite element method. Then the dynamic mechanical properties were tested at different current. The results show that the designed structure of the magnetorheological elastomer isolator is reasonable. And the dynamic stiffness increases as the current increasing, As the current reaches 2A, the dynamic stiffness increases slowly. Therefore, the isolator has excellent magnetorheological effect.
