Research on Missile Vibration Characteristics Considering Engine Vibration Based on Mstmm

Missile has the advantages of fast speed and strong penetration ability. It has become the main way of high precision strike in modern battleground. The vibration of the missile engine will affect its safety and stability during the active flight. In this paper, Reduced multibody transfer matrix method is used to introduce engine vibration in the missile model considering thrust, establish a missile dynamics model of the active segment flight, derive the total transfer matrix and total transfer equation, and quickly and accurately calculate the transient response of the active segment flight of a certain type of missile, which provides an effective method for studying the influence of engine vibration on the flight performance of the active segment of the missile.
