Free Vibration Frequencies of Lock Gate Structure
The effect of incompressible fluid on free vibration frequencies of a stiffened lock gate structure is investigated. The formulation of a stiffened lock gate consists of plate and beam elements. Mindlin’s plate bending and Euler’s beam theories are used for the plate and the stiffener, respectively. The fluid is assumed to be inviscid and incompressible, having an irrotational flow. The infinite far boundary of the fluid domain is truncated near the lock gate structure using Fourier half-range cosine series expansion in the solution of the Laplace equation. Finite-element method (FEM) is used to establish interaction between the fluid and the lock gate. The finite-element formulation is then converted into computer code to determine the free vibration frequencies of the stiffened lock gate in the presence of fluid. The results are compared with the unstiffened lock gate by approximately keeping the same volume of material.
