某型机弹性体和刚体离散突风动响应载荷比较分析

在运输类飞机设计过程中，突风动响应载荷计算是其中的重要一环。各类适航规范都要求在突风动响应载荷计算中考虑飞机弹性模态的影响,而弹性体和相应的刚体飞机的突风动响应载荷计算之间存在着紧密的联系。为了研究两种计算方法间的区别和联系，本文首先从计算理论方面进行了分析，然后结合某型机载荷计算数据在数值结果方面进行了进一步的比较分析，最后得到了关于两种计算方法间区别和联系的一些规律性的结论。希望本文对相关领域的研究人员能够有所启发。

Comparative analysis of flexible and rigid body dynamic discrete gust loads of an airplane

In the design procedure of transport category airplane, dynamic gust loads analysis is indispensable. All kinds of airworthiness regulations require that the elastic modes of the airplane must be taking into account in the dynamic gust loads calculation. Besides, there is an inextricable connection between the dynamic gust loads calculation of flexible airplane and its rigid counterpart. To study the differences and relationships of these two kinds of approaches, the basic theory of gust loads calculation is analyzed at first. Then, comparative analysis is carried out on the numeric results according to the data calculated for the dynamic gust loads of one airplane. At last, some conclusions are drawn about the differences and relationships of the two kinds of approaches. It is hoped that this paper could inspire people who work in relative fields.
