摘要：

针对导弹六自由度数学仿真中的弹体弹性模型，开展弹性振动抑制的验证方法研究。介绍了用于导弹弹性振动抑制的陷波滤波器，分析了导弹飞行主动段和被动段中滤波器设计的验证思路，指出了目前在数学仿真验证中存在的问题。基于调频现象提出了一种频率补偿的陷波滤波器在线验证方法，通过对频率补偿函数进行理论推导可发现，该函数可适用于任何阶次的弹性频率验证。通过构建弹体弹性频率补偿函数实现了对所设计陷波滤波器的验证，不仅验证了弹性频率的陷波深度与理论设计值一致，还可以模拟不同弹性频率的基本特性。

Abstract:

For the elastic model of missile body in six degree of freedom mathematical simulation, the research on the verification method of elastic vibration suppression is carried out.. The notch filter used for elastic vibration suppression is introduced, the verification idea for filter design in boost-phase and passive-phase stages of missile flight is analyzed, and the problem currently existing in mathematical simulation verification is pointed out. Based on the frequency modulation phenomenon, an online verification method of frequency compensation for the notch filter is put forward, and it can be found that the function can be applied to any order of elastic frequency verification through the theoretical derivation of the frequency compensation function. The verification of the designed notch filter is achieved by constructing the frequency compensation function of the missile body elastic, which not only verifies that the notch depth of the elastic frequency is consistent with the theoretical design value, but also simulates the basic characteristics of different elastic frequencies.

Key words: elastic suppression, notch filter, verification method, frequency modulation phenomenon
