弹丸膛内运动模型的研究

A Study of the Model of Projectile Motion in Bore

本文给出了弹丸膛内运动方程,提出了弹丸前定心部与炮膛内壁的两种接触方式,分析了弹丸在前定心部紧贴膛壁时的运动情况。

This paper has given the equations of motion of projectile in-bore, advanced two contacting patterns between the bourrelet of projectile and the inwall of the bore, and analysen the movement of the projectile when its bourrelet touching the inwall of the bore.
