摘要
对几种斜拉索的阻力系数进行了研究,得到阻力系数对于倾角及雷诺数变化的曲面拟合函数,曲面图直观地显示了阻力系数变化。表面花纹索和表面螺旋线索的阻力系数变化较为相似,都比光洁索的阻力系数变化要平缓,但表面花纹索的阻力系数要略小于螺旋线索。
Drag coefficients of some types of stay cables have been investigated in this paper. By surface fitting, we get the drag coefficient as a function of inclination angle and Reynolds number, and figures of functions can display the variation of drag coefficients clearly. Generally, drag coefficient of dimpled surface cable are similar to that of the helical surface cable, but dimpled surface cable＇s drag coefficient is a little lower than helical surface cable＇ s.
