Abstract:We have considered two configurations of cantilever beam for characterization of rheological properties (density and viscosity) of viscous material. Both the beams are made of thin steel foils, having different free end condition. The beams were vibrated in various viscous fluids such as water and lubrication oils under sweeping modes, and the frequency response of the beam was measured using Polytec laser vibrometer. For both beam configurations, the resonance frequency decreased while the width of the resona… Show more
