Abstract: This paper offers a new approach to small-scale design optimization which combines the philosophy of R. C. Johnson’s Method of Optimum Design with the use of a relatively simple and concise ...

Abstract: A method of analysis of tidal flap doors under oscillatory flow conditions is presented. Hydrodynamic data for flap doors is given for use in numerical simulation of door movement. Application of the data is illustrated ...

Abstract: Recent theoretical work by Tichy and Bou-Said (1991) and El-Shafei and Crandall (1991) has resulted in new theoretical expressions for the nonlinear inertia forces for both short and long ...

Abstract: The experimentally determined behavior of a short radial squeeze-film damper with no end seals, executing circular centered orbits, is discussed. Accurate circular orbits were achieved, for ε ...

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 ...

Abstract: The state variable filter method of parametric identification is applied in the determination of squeeze-film dynamic coefficients from forced excitation tests on an experimental rig. The experimental ...
