来风

Regarding structure under wind load function crosswind upward power response, because comes the wind to receive running free to the wall surface impediment, has the vortex tattered and wind direction change, with the running free wind cutting hit, the wind power become further complex.

对于结构在风荷载作用下横风向上的动力响应，由于来风受到顺风向壁面的阻挡，发生漩涡破碎和风向改变，与顺风发生剪切撞击使得风力结构进一步复杂。

The wind power plant's actual active power depends on the influence of wind, changing from zero to the maximum, The junction's variation of voltage rate between the wind power plant and main electrical power network is very big.

风电场实际发电量受来风的影响从零至最大发电量之间变化，使风电场与主网连接点的电压变动率很大。

In the past wind tunnel investigations were the main way to study the aeroelastic problem. When evaluating the aeroelastic stability of a long-span bridge under wind, it is mostly assumed that wind normal to the bridge span is most unfavorable.

以前主要以风洞试验为主要研究手段。在研究风荷载作用下的大跨度桥梁的气动稳定性时，经常假设来风的方向与桥跨正交时是最不利的。
