Article Preview

Mechanical damping systems have been widely used to various industrial structures and are mainly hydraulic and pneumatic devices nowadays. This article presents an experimental investigation of a nano colloidal damper. Particularly for colloidal damper, the hydraulic oil is replaced by a colloidal suspension, which is consisted from a nano-porous matrix with controlled architecture and a lyophobic fluid. Nano colloidal damper test rig and the measuring technique of the hysteresis were described in this study. Influence of the water volume and particle diameters upon the nano colloidal damper hysteresis was investigated. As a result, the proposed nano colloidal damper (NCD) is proved as an effective one, which can be replaced for the conventional hydraulic damper.
