摘要
基于二阶浮力原理,着重研究了磁性液体阻尼减振器不同壳体内壁、不同端盖锥角对减振器减振性能的影响。通过试验分析得知粗糙内壁的壳体减振性能优于光滑内壁的壳体;在一定范围内,端盖锥角大的减振器减振性能比端盖锥角小的减振器减振性能好。
Here, the effects of different inner surfaces and cone angles of a magnetic fluid damper on its vibration reduction performances were studied with tests based on the theory of second-order buoyancy. The test analysis results showed that the vibration reduction performance of a shell with rough inner surface is better than that of a shell with smooth inner surface; the vibration reduction performance of the damper with a larger cone angle is better than that with a smaller one in a certain range.
