摘要
依据某型发射装置及导弹的结构,利用Partran/Nastran软件建立发射装置及导弹系统的振动特性模型,并计算出该系统的固有频率,分析三个主要因素对系统振动特性的影响,在此基础上对发射装置进行改进设计,实现对发射装置的振动特性设计,避免"机翼-发射装置-导弹"之间共振的发生。
According to the structure of some launcher and missile,the vibration characteristic model of the launcher and missile system is built by Partran/Nastran,and then its nature frequencies are calculated.Through analyzing,the influence of three main factors on the system vibration characteristic is gotten,and the ameliorate design of launcher is made.This actualizes the vibration characteristic design of launcher,avoids the resonance among the airfoil,launcher and missile.
