Abstract

This paper presents design and performance evaluation of MR damper for the reducing vibration of a flexible pipe conveying fluid. A novel type of MR damper which is suitable for pipe vibration characteristics is proposed and the MR damper is mathematically modeled and its damping force characteristics are evaluated. The vibration control performance of the MR damper associated with The cantilever pipe system is evaluated.
