Influence of Installation Angle of a Damper Using a Magnetic Particle Assemblage on Damping Force under Applied Magnetic Field

Abstract

　Damping force of the damper using a particle assemblage depends on installation angle of the damping due to gravity acting on the particles and existence of space in the container of the damper. In order to suppress such dependency of installation angle, magnetic particles are used as particle assemblage in the damper and magnetic field is applied by using two electromagnets or permanent magnets. It is shown that the effect of installation angle on the damping force is reduced by using applying magnetic field.
