摘要
为实现新型防暴枪的恒定动能打击,提出了在身管内增加刚性凸起增大弹丸挤进阻力的变初速原理。建立了刚性凸起的变初速计算模型,利用LS-DYNA软件探索了凸出量变化对弹丸初速的影响规律,并通过调节刚性凸起的凸出量,拟定了在12 J/cm2,16 J/cm2,22 J/cm2的三种恒定打击动能条件下初速调节设计方案。
In order to realize new riot guns constant energy lethality,this paper puts forward the addition to rigid outthrust in the tube to increase the engraving resistance for projectile,establishes variable muzzle velocity model for the rigid outthrust and uses simulation software LS-DYNA to explore the relationship between the bugle volume and the muzzle velocity.At the same time,through adjusting the bugle volume of outthrust protocol underl2J/cm2,16J/cm2,22J/cm2three energy lethalities,it works out the variable muzzle velocity shoot design scheme.
