碩士 / 正修科技大學 / 機電工程研究所 / 100 / The purpose of this study is to determine the exact natural frequencies
and mode shapes of the filled multi-liquid hollow pile with elastic-supported
tip inertias immersed in a water. To this end, the coefficient matrices for an
intermediate pinned support, an intermediate concentrated elements, up-end
support and down-end support of a beam are derived, first. Next, the overall
coefficient matrix for the whole structural system is obtained. Finally, the
natural frequencies and the associated mode shapes of the vibrating system
are determined by equating the determinant of the last overall coefficient
matrix to zero and substituting the corresponding values of integration
constants into the associated eigenfunctions, respectively. The effects of
various concentrated elements, liquid height and water height of the hollow
pile are also studied.
