超空泡射弹运动过程模拟仿真及有限元分析

Simulation of Supercavitating Projectile Motion Process and Finite Element Analysis

利用Matlab模拟仿真弹丸在水中的运动情况,将仿真结果代入ABAQUS对弹丸进行有限元仿真,分析弹丸在水中运动时各个节点的应力变化情况,找出了弹丸在水中运动时最容易发生破坏的危险区域,该区域的强度和刚度都是在设计弹丸时应该重点考虑的部位。

Using Matlab simulation of the motion of the projectile in the water, we made the simulation re- sults into projectile ABAQUS finite element simulation analysis, analyzed the projectile motion in water stress condition of each node to indentify the projectile motion in the water most likely to occur when the damage. The area that the strength and stiffness are focus should be considered when designing the projec- tile parts.
