Effects of Magnetic Fluid on Magnetic Fluid Damper
A magnetic fluid damper which based on the principle of second-order buoyancy of magnetic liquid has been presented.During the process of damping,besides the elastic deformation of magnetic liquid adsorbed by permanent magnet,the main ways of energy dissipation are the friction functions,which include the friction between magnets and magnetic liquid,magnetic fluid and magnetic fluid and magnetic fluid and the shell of the damper.In order to investigate influence of magnetic fluid on damping effect,a series of experiments under different magnetic fluid with related parameters including magnetic fluid volume and saturation magnetization are carried out.It is found that both volume and saturation magnetization of magnetic fluid have optimal value on the damping effect of the damper.
