利用磁流变液流变特性随外加磁场的变化而变化的智能特性。以磁流变液阻尼器件工作模式为基础 ,详细介绍了磁流变减振器的设计原理以及对实际磁流变减振器的实验。调节激励电流可调节磁流变减振器的阻尼力 ,而且磁流变减振器功耗和噪声小。为防止压缩时出现无阻尼空行产生冲击 ,在磁流变减振器中必须加入补偿措施。实验结果表明 ,磁流变减振器功耗低 ,噪音小 Using the rheological properties of MR fluids as a function of external magnetic field changes. Based on the operating mode of MRF damper, the design principle of MR damper and the experiment of MR damper are introduced in detail. Adjusting the excitation current can adjust the damping force of the MR damper, and the MR damper consumes less power and noise. In order to prevent the occurrence of compression without damping blank row impact, in the MR damper must be added compensation. The experimental results show that the magneto-rheological absorber has low power consumption and low noise
