摘　　要：研究了战术导弹在穿越离散突风区域时,弹体的动力学响应及产生的动载荷.首先,给出了导弹在穿越突风区时的运动方程,其中不仅考虑了弹体的刚体运动,而且考虑了弹体各分站位置及空气舵位置的结构动力学响应引起的附加攻角,以及突风对空气舵的滞后影响效果等.其次,建立了导弹结构动力学模型和"1-cos"突风模型,并给出了弹体动载荷计算公式.最后,通过算例研究了导弹在穿越突风过程中,弹体的动力学响应以及载荷计算问题.When the tactics missile flies across the discrete gust, its dynamic responses and load were investiga- ted. Firstly, the kinematics equations of the missile were put forward, which took into account the influence of structure dynamic on the additional angle-of-attack of all key section and air helm and the lag effect of the discrete gust on air helm. Secondly, the structure dynamic model of the missile and ＇ 1-cos＇ gust model were established, and the formula of dynamic load was given. At last, the dynamic responses and the load of the missile were stud- ied by example.
