摘要
描述了连续阵风载荷计算的方法及其应用。在紊流气动力、结构振动附加气动力、弹性力及惯性力的耦合作用下,通过在频域内联立求解结构振动方程,获得了响应量(位移、载荷)的频响函数。并依据民用飞机适航条例要求进行了垂向阵风载荷计算。
This paper focuses on the theory method and application of the continuous gust loads for the airplane. The main idea is that under the three coupling actions of unsteady air force, elastic force and inertial force, establishing the flexible movement equation, and then calculating the response function of frequency of output quantity (the displacement, load factor, load) in the frequency domain. It also calculated the vertical gust loads accord- ing to the airworthiness requirements of civil airplane.
