| Abstract: | In this paper, the free vibration of an elliptic reservoir partially filled with liquid and submerged in water is studied. Calculating formulae of exact function of vibration modes and frequencies which could be used on computers are proposed. The study demonstrates that the effects of internal and external liquid on the vibration of reservoir are just equivalent to generalized ditributive mass attached to the elliptical column. |
