| 摘 要： | 本文采用Flügge壳体理论,研究了密加肋圆柱壳在深水流场中受到径向冲击载荷作用时的瞬态动力响应;讨论了冲击载荷作用面积、水深和肋骨间距及惯性矩对环肋柱壳动力响应的影响,并与有关文献的计算结果进行了比较,表明研究壳体在流场中振动问题时必须考虑流固耦合的影响.

| Abstract: | An analytical study is made for evaluating the transient dynamic response of submerged ring-stiffened cylindrical shells under radial impact loading. Flugge's thin shell theory is used in the formulation of equations of motion and fluid-structure coupling is taken into account. Solutions are obtained through wet modal expansion. The influences of hydrostatic pressure, size of loading area and variable ring cross-section and pitch on the response are discussed. Numerical results obtained are compared with those published by other investigators. The comparison shows that it is necessary to take fluid-structure coupling into account when the vibration of submerged shells is studied. |
