Exploratory studies of liquid behavior in randomly excited tanks - Longitudinal excitation

Abstract

This report presents results obtained in a n exploratory investigation of the behavior of fluid in a cylindrical tank under relatively low frequency random longitudinal excitation.tude nonlinear f r e e surface response is possible under some conditions of random excitation.w e r e obtained only on the tank axis, the results strongly indicate that the l a r g e amplitude fluid response is of the 1/2 subharmonic type observed under harmonic excitation.Data on the probability structure of the nonlinear free surface response a r e also presented.It was found that large ampli-Though quantitative data on f r e e surface elevations V
