着眼于工程应用,从弹性飞行器一般运动方程的角度,提出了导弹颤振抑制的主要思路,总结了常规导弹颤振分析的一般流程.分别从质量特性和刚度特性两个方面,阐述了导弹颤振抑制的方法和需要注意的问题.算例分析表明,配重设计可有效提高颤振速度,但对不同的颤振类型配重效果有所不同.最后,以舵轴位置变化对舵面颤振性能的影响为例,说明结构布置与导弹颤振性能的关系.算例表明,如结构布置合理,可缓解颤振设计的压力.
Focusing on the engineering application, the main idea of missile flutter suppression is proposed from the perspective of the general equations of motion of the flexible aircraft, and the general flow of the flutter analysis of the conventional missile is summarized. From the two aspects of mass and stiffness characteristics, Vibration suppression method and problems needing attention.An example analysis shows that the counterweight design can effectively improve the flutter speed, but different flutter type weight effect is different.Finally, the rudder shaft position changes on the rudder flutter Vibration performance as an example to illustrate the relationship between the structural arrangement and the flutter performance of the missile.Examples show that if the structural arrangement is reasonable, the pressure of the flutter design can be relieved.
