摘　　要：针对弹丸发射强度的分析方法的多样性,提出一种在变膛压作用下同时考虑阻力作用的弹丸强度分析方法。以某底凹弹的发射强度分析为例,应用Matlab和ANSYS Workbench实现了对该弹丸在变膛压作用下的发射强度仿真。通过提取仿真结果发现,在变膛压作用下,弹丸最大等效应力和等效弹性应变与膛压变化并不成正比,二者在发射过程中存在一定的波动;本文所提出的方法可为弹丸的发射强度分析提供新的途径。In view of the diversity of analysis methods of projectile launching strength,a new method of projectile strength analysis considering resistance effect under variable bore pressure is proposed.Taking the launching strength analysis of a concave projectile as an example,Matlab and ANSYS Workbench are applied.The simulation results show that the maximum equivalent stress and equivalent elastic strain of the projectile are not directly proportional to the change of chamber pressure,and there are some waves in the process of launching.The method proposed in this paper can provide a new way for the analysis of the launch intensity of the projectile.
