Abstract: This study takes the elongated flexible spacecraft as the research object, and takes the realization of solar system edge exploration as the mission traction to carry out the research on the dynamics and stability characteristics of this kind of spacecraft in the process of prolonged space flight. Firstly, the elongated flexible spacecraft dynamics model is established to analyze the structural vibration characteristics and mechanism motion characteristics; secondly, the elongated spacecraft spin dynamics model is obtained based on the complete dynamics model, and the spin stability characteristics are analyzed when the truss flexibility is considered; then, the spin motion evolution characteristics of the elongated flexible spacecraft are analyzed from the perspective of the energy and angular momentum evolution; finally, we analyze the flight environment characteristics of the elongated flexible spacecraft in the solar system marginal exploration mission, and numerically simulate and analyze the spin stability characteristics of the elongated flexible spacecraft under the conditions of no external perturbation, constant perturbation moment under the local system, and planetary borrowing flight, and give the spin stability conclusions and quantitative impact analysis of the destabilizing factors for the above cases.
