摘要
针对T/D=3.5的并列双圆柱体在均匀流场中的动态特性进行了实验研究.测出了柱的流向及横向振动响应,以及柱表面分布压力.经分析后,本文给出了柱的流向、横向之振动频率及位移随约化速度变化的关系,同时给出了各种柱表面压力系数沿柱周向的分布曲线;最后对弹性柱的Strouhal数给予了适当的讨论.
For T/D=3.5, the dynamic responses and the pressures on the surface of two cylinders of the same diameter in side-by-side arrangement subjected to uniform stream are studied experimentally.Through analysing, the frequencies and the displacements in the lift and drag directions, which change with reduced velocities, are given in the present paper.Meanwhile, various pressure coefficients are drawn.In the end, Strouhal number for elasfic cylinder is properly discussed.
