设计了一种新型差动自感式磁流变阻尼器(DSMRD),研究中发现该阻尼器中的绕线缸体在磁场中容易产生漏磁现象。基于此现象,建立了不同绕线缸体材料的DSMRD磁场仿真模型,对绕线缸体构成材料与漏磁之间的关系进行了仿真分析。仿真结果表明:导磁缸体较不导磁缸体具有更好的磁场吸附能力,且能产生更高的感应电动势;采用铝和不锈钢这两种不导磁材料制成的绕线缸体产生的磁场强度接近,并且产生的感应电动势也基本相同。因此可通过改变绕线缸体材料来达到优化DSMRD的自感磁场和阻尼磁场的目的。
A new type of differential self-inductance MR damper (DSMRD) is designed. It is found that the bobbin in the damper is prone to magnetic flux leakage in the magnetic field. Based on this phenomenon, the DSMRD magnetic field simulation model of different wound cylinder materials was established, and the relationship between the material of the wound cylinder and the magnetic flux leakage was simulated. The simulation results show that the magnetically permeable cylinder has better magnetic field adsorption capacity than the non-magnetically permeable cylinder and can generate higher induced electromotive force. The winding cylinder made of two non-magnetic materials, such as aluminum and stainless steel, The magnetic field strength is close, and the induced electromotive force is basically the same. Therefore, by changing the winding cylinder material to achieve self-inductance DSMRD magnetic field and the purpose of damping the magnetic field.
