您要查找的是不是:
- flat box wind speed 扁平箱形截面
- The variation pattern between flutter critical wind speed of bridge with flat box deck and wind yaw angle is significantly affected by wind attack angle. 扁平箱形截面桥梁的颤振临界风速与风偏角的关系明显地受到风攻角的影响。
- However, in the case of non-zero attack angle, the flat box deck becomes bluff, the variation of its flutter critical wind speed is accordingly undulant as the wind yaw angle increases, and the lowest value will occur generally under skew wind. 而对于非0°风攻角的情况,扁平箱形断面的流线性变差,随着风偏角的增加其颤振临界风速呈起伏变化,最低值一般在斜风的情况下出现,此时,传统的平均风分解方法不再适用。
- Three stages wind speed control. 三段风速控制。
- The wind speed had to be just right. 风速必须得恰倒好处才行。
