摘要
本文研究贮液椭圆筒在水中的横向自由振动问题,给出了贮液椭圆筒在水中横向自由振动的振型函数和固有频率的精确计算公式,结果可由计算机解出。同时指出,内外液体对椭圆筒振动的影响等效一附着于筒体上的广义分布质量.
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.
