A Finite-Element Model for the Olmsted Wicket.

Abstract

This report presents the step-by-step updating procedures to develop an analytical finite element (FE) model of the Olmsted wickets. The FE model was validated using results obtained from both dry and wet experimental modal analyses and static and flow-induced dynamic experiments. Geometric dimensions, physical properties, and experimental modal data were correlated with the analytical model to ensure the correct distribution of mass and stiffness of the model. Wet modal parameters were used to define the added mass distribution of the operational gate. Time-history comparisons were used to measure the effectiveness of the model in simulating the flow-induced vibrational response of the Olmsted wickets for various operational and flow configurations. This report also describes the uses of the model for evaluating the dynamic performance of the operational wicket.
