Influence of Installation Angle on Damping Force of Damper Using a Particle Assemblage

Abstract

   In this paper, influence of installation angle of the damper utilizing fluidity of particle assemblage on damping force of the damper is investigated experimentally. The experiment was performed under installation angles of 0 (horizontality), 30, 60 and 90 (verticality) degrees. It is found that damping forces under 30 to 90 degrees of installation angles are larger than that under 0 degree of installation angle when the piston of the damper moves downward. And maximum damping force takes largest value at 60 degree of installation angle. On the other hand, by using inner capacity variable damper which comprises spring, installation angle has any influence on characteristics of damping force of the damper.
