基于Adams软件对掠飞末敏弹的膛内运动过程进行了动力学仿真分析。考虑掠飞末敏弹的结构非对称性,重点分析了质心位置、转动惯量等结构因素对掠飞末敏弹膛内运动正确性的影响。仿真结果分析表明:弹丸结构非对称时,弹丸与炮膛间接触次数和受力大小均明显增大;弹丸质心位置改变造成接触力增大,初始摆动角增大;转动惯量改变时,初始摆动角增大。

Dynamics simulation analysis on movement process of swept flight assault roof (SFAR) terminal-sensitive projectile (TSP) in bore was made by Adams software. Considering structural asymmetry of SFAR TSP, analyzed the influence of structural factors including centroid location, moment of inertia, etc on the motion process of SFAR TSP in bore. Simulation results show that: when the structure of projectile is asymmetric, the number and force size of contact between bullet and bore increase significantly. Changing the projectile centroid position causes increase of the contact force and the initial swing angle. When the moment of inertia changes, initial swing angle increases, too.
