Abstract

A numerical-analytical method is proposed for calculating the forced vibrations of a shell structure immersed in liquid. The structure is a set of finite elastic cylindrical shells and elastic rings to which concentrated discrete forces are applied. Examples of a comparative calculation of the frequency response and vibration modes of the shell structure in a vacuum and in liquid are given.

浸入液体的圆柱壳的强迫振动

摘要

提出了一种数值分析方法来计算浸没在液体中的壳体结构的强迫振动。该结构是一组有限的弹性圆柱壳和弹性环，施加了集中的离散力。给出了在真空和液体中壳结构的频率响应和振动模式的比较计算示例。
