模拟弹丸挤进过程的弹丸变形应力

Analysis on Material Deformation and Stress in the Simulated Process of Driving Band Engraving for Projectile

自动武器弹丸挤进以及在内弹道这一阶段很难通过枪支原型的实验来得到准确的数据,而弹丸的挤进却又对设计精度、材料磨损等情况有很大的关联。运用仿真软件ANSYS建立了一组简化的2D模型,对其进行了应力应变及变形分析,为后续的研究提供一定的科学依据。

The engraving process of automatic weapons and interior ballistics is difficult to get accurate data through the guns of the prototype experiment and the engraving related to design precision and material abrasion and so on.So this paper uses simulation software ANSYS to establish a set of simplified 2D model,and carries on the analysis of stress,strain and deformation,and also it can provide some scientific basis for successive research.
