摘要
提出了一种基于二阶浮力原理的磁性液体阻尼减振器设计方法。通过选择磁性液体种类、永久磁铁材料和形状以及减振器壳体材料和外形,设计制造了磁性液体阻尼减振器,并进行了减振试验。试验重点研究了减振器端盖锥角及减振器内永久磁铁与壳体的间隙对减振器减振性能的影响。通过试验分析得知端盖锥角以及永久磁铁与壳体间隙都存在最佳值使得减振器减振性能最优。
A magnetic fluid damper based on the principle of second^rder buoyancy is proposed. The type of magnetic fluid, materials of permanent magnet and materials of damper shell are selected for designing the structure of the magnetic fluid damping shock absorber, and experiments are carried out based on designed magnetic fluid damping shock absorber. This study focuses on the damping effect by adjusting the gap of the permanent magnet and damper shell, the magnetic fluid damper end cap cone angle. Analysis shows that there exists an optimum gap and cone angle which make the optimum damping performance.
