Flow Mode Magnetorheological Dampers with an Eccentric Gap

Advances in Mechanical Engineering, 2014
This paper analyzes flow mode magnetorheological (MR) dampers with an eccentric annular gap (i.e., a nonuniform annular gap). To this end, an MR damper analysis for an eccentric annular gap is constructed based on approximating the eccentric annular gap ...

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors

Advanced Materials Technologies, EarlyView.
This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Dynamic analyses of adjacent buildings connected by fluid viscous dampers [PDF]

WIT Transactions on The Built Environment, 2009
Building structures are often built close to each other because of lack of available land in metropolitan cities. In this study, the effectiveness of fluid viscous dampers is investigated in terms of the reduction of displacement, acceleration and shear force responses of adjacent buildings. The specific objectives of this investigation are carried out
