RISA Comparison of Identification Methods for Estimating Squeeze-Film Damper Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of identifying the dynamic coefficients relating to inertia, damping, and stiffness, in a single degree of freedom model of squeeze-film behavior, is discussed. It is demonstrated ...
The Determination of Squeeze Film Dynamic Coefficients From Transient Two-Dimensional Experimental Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A state variable filter (SVF) method of identifying parameters in lumped-parameter systems is extended to accommodate multi-degree-of-freedom problems. The method is computationally efficient and ...

The Complete Determination of Squeeze-Film Linear Dynamic Coefficients From Experimental Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the use of the State Variable Filter (SVF) method of parametric identification to estimate the complete set of twelve linear hydrodynamic coefficients for a squeeze-film ...
ER Shear Characteristics: Volume Fraction, Shear Rate, Time Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electro-stress and electron-hydraulic time delay are investigated in shear mode tests on ERF (electro-rheological fluid). These parameters are examined using a concentric, Couette clutch operating ...
