Abstract

An analytical model is presented to describe the vibration of a truncated conical shell with fluid loading in the low frequency range. The solution for the dynamic response of the shell is presented in the form of a power series. Fluid loading is taken into account by dividing the shell into narrow strips which are considered to be locally cylindrical. Analytical results are presented for different boundary conditions and have been compared with the computational results from a boundary element model. Limitations of the model to the low frequency range are discussed.

摘要

提出了一个分析模型来描述低频范围内承受流体载荷的截顶圆锥壳的振动。以幂级数的形式给出了壳体动态响应的解。通过将壳体划分为窄条带并将其视为局部圆柱形来考虑流体载荷。给出了不同边界条件下的分析结果，并与边界元模型的计算结果进行了比较。讨论了该模型在低频范围内的局限性。
