摘要
应用“自动动态增量非线性分析”程序，计算了某高初速杆式穿甲弹在发射初期，当弹带为尼龙、铜质等不同材料时，弹内动态应力和弹带压力变化情况；并就尼龙弹带前倾角的变化对应力分布的影响作了计算分析，确定了尼龙弹带在给定尺寸情况下的弹带压力分布、弹带变形情况等，最后就几种情况作了较详细的分析探讨。
The dynamic stresse in sabot and band and band pressure of a certain kind of projectile during launch period were found using an“Automatic Dynamic Increase Non-linear Analysis Code”,The effects of thesizes of nylon band on the stresses distributions in sabot were calculated andanalysed.Finaly,when the band were different nylon and some brass,thedynamic stresses in sabot,band pressure and deformations we re discussedrespectively.
