The authors discuss a new numerical simulation method of the downburst wind loads on the basis of the previous research. Firstly, the wind speed is expressed as the sum of an instantaneous mean wind speed and an amplitude-modulating non-stationary fluctuating wind speed. Secondly, a new method based on the modified Osegguera and Bowles/Vicroy model to simulate the mean wind is presented and the fluctuating wind is simulated by a modified spectral representation method.

在将下击暴流风速表达为时变的平均风速和调制的非平稳脉动风速之和的前提下，本文采用基于改进的OBV模型Oseguera and Bowles/Vi-croy(OBV的方法来模拟平均风速，其平均风速直接由改进的OBV模型表达，而不同于已往研究中将平均风速表达为竖向风剖面与时间函数的乘积，并采用结合快速傅里叶变化的谐波叠加法来模拟调制的非平稳脉动风速。

After undergoing a chaotic region, the period number will add one, in the same time, magnitude of the subharmonic response increases in sequence as the rotational speed ratio increases. When the rotational speed is below the critical speed, the chaotic bands resulted directly from a perioddoubling bifurcation occur among the successive orders of superharmonic responses, then they can return directly to periodic motion by a reversed period-doubling bifurcation.
