Numerical Simulation of Armour-piercing Warhead Penetration Process

文章论述了用基于LS-DYNA的动力学分析通用有限元程序对穿甲战斗部侵彻过程进行数值仿真。阐述了数值仿真模型的建立,以及利用数值模拟技术,实现了侵彻过程中弹体的变形与靶板的破坏状况可视化,同时对仿真结果进行了分析,并进行了靶场实验验证,仿真结果与实际情况基本相符。通过对穿甲战斗部侵彻过程数值仿真,为开展穿甲战斗部穿甲机理研究奠定良好的基础。

Researched armour-piercing warhead penetration process with the way of numerical simulation based on LS-DYNA, it was a program that analyse dynamics. Discussed how to establish the numeric simulation model of armour-piercing warhead destroying target and using the technique of numerical simulation, the status of warhead distortion and target demolished can be observed at the same time, analysed the emulational result and validated by contrasting emulational result and test result. The emulational result is basically fight. By researching armour-piercing warhead penetration process with the way of numerical simulation, establishing favorable base for researching armour-piercing warhead penetration mechanism.
