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。
The study on the flowinduced instability of clampedpinned coaxial cylindrical shells is carried out based on Padoussis' mathematical model and analytical method. The results show that the critical flow velocity of a clampedpinned shell system is lower than that of a clampedclamped shell system.
