摘要

在常规的TWIST编谱方法的基础上,通过改进的方法来更简单地实现TWIST编谱方法中突风载荷谱对数正态极值分布准则、突风载荷谱形状相似准则以及每次飞行机动循环数近似相同(地面机动同一数量级,飞行机动两数量级之内)准则,最终通过引用和国产大飞机同类别的国外飞机的载荷数据,参照B737-400机型的飞行谱,采用类比法,分析和推断出国产大飞机的飞行谱.这个算例也验证了这种方法的合理性和准确性.%On the base of the conventional TWIST spectra method,it is made some improvements to make the gust load spectra logarithmic normal distribution rule,the approximately same gust load spectra shape rule and the approximately same maneuver cycle number rule（The ground maneuver has the same order of magnitude,the flight mobile is within two orders of magnitude ）realize easier.At last,use the load data of the foreign aircraft that is similar to domestic big aircraft,refer to the flight spectrum of B737-400,use the analogy method,analysis and conclude the flight spectra of domestic aircraft,The numerical example shows that this method is reasonable and accuracy.
