风电塔架风速时程曲线与风荷载时程曲线模拟。本代码依据IEC 61400-1标准，用于模拟具有一定功率谱密度和自相关性的风速时程曲线，并计算叶片及塔架上的风荷载。方法为基于三角级数叠加的谐波合成法（Hansen，2008）和叶素动量法。功率密度谱采用Kaimal谱函数。(Curves of wind speed and wind load-time curve Cheng wind tower. The code according to IEC 61400-1 standards, and procedures used to simulate the spectral density curve has a certain power the time correlation of wind speed and calculate the wind load on the blades and tower. The method is based on trigonometric series superposition of harmonic synthesis (Hansen, 2008) and the blade element momentum method. Kaimal power density spectrum using spectral function.)
