Abstract

Abstract: Folding tail mechanism is widely used in subsonic and super/high sonic missiles, and its mission reliability is directly related to the success or failure of missile launch. Taking the torsion bar folding tail mechanism as the object, the failure modes and failure influencing factors in the mission process are analyzed systematically. The dynamic model of the folding tail mechanism is established. According to its characteristics, the multi-stage correction method of the dynamic model is proposed and realize the high-precision simulation. Finally, the mission reliability and sensitivity analysis is carried out, and the reliability sensitivity of folding tail mechanism is obtained, which lays the foundation for reliability optimization.
