An Experimental Study of the Dynamic Characteristics of Viscous Fluid Dampers

This study was performed to obtain a numerical model for a viscous fluid damper from an experimental testing. The input signals for displacement were chosen as two types : a triangular and a sinusoidal forms. The performing test parameters were the area of the resistant plate, relative velocity between resistant plate and base plate, oil film thickness of the viscous fluid, but the temperature effect was neglected. The numerical model was established by assuming an non-Newtonian fluid behavior. The test results were summarized by the equation of F= 0.0308(ν/d)0.5125. Using the obtained for a real structure design was introduced.
