Abstract

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.
