螺旋管管阵流弹不稳定性的实验研究——螺旋管管阵固有频率的测量

The Study for Fluidelastic Instability of Helical Tube Arrays The Measurement for natural frequency of helical tube arrays

对螺旋管管阵在两端固支条件下的固有频率和阻尼进行了实验测定。

The natural frequency and damping of helical tube arrays fixed at two ends are measured.The experimental results help the study of fluidelastic instability of helical tube arrays.
