  • 摘要: 基于Pa doussis等同轴圆柱壳体流致不稳定性的数学模型和研究方法,分析了固支 简支端部约束条件下同轴圆柱壳体系统的流致不稳定性。结果表明:同两端固支相比,固支 简支端部边界下壳体系统的失稳临界流速更低。

     

    Abstract: The study on the flowinduced instability of clampedpinned coaxial cylindrical shells is carried out based on Padoussis' mathematical model and analytical method. The results show that the critical flow velocity of a clampedpinned shell system is lower than that of a clampedclamped shell system.
