摘要
利用磁流体作减振器减振液 ,通过控制磁流体的粘度系数可达到控制减振器性能特性的目的。利用有限元法对 1 / 4减振器节流孔模型进行电磁场分析 ,结果显示节流阀体材料的磁性对节流孔内磁流体外加磁场强度存在明显影响。采用非磁性材料做阀体比采用磁性材料做阀体效果要好 ;减振器的所有磁性组件对磁流体的附加外磁场都有贡献 ,特别是线圈放置于缸体内部是实现磁屏蔽。
The electromagnetic field of a 1/4 shock absorber model is detailed by using Finite Element Analysis (FEM). The results show that the magnetism of valve body materials has an evident influence on the magnetic field intensity in the orifice of a shock absorber, and the effect of a valve body made of a nonmagnetic material is better than that made of a magnetic material. All the magnetic components in a shock absorber contribute to the additional magnetic field intensity. It is a good way to settle a coil in the shell of an absorber to defend it from magnetic interference and avoid magnetic leakage.
