一种大口径战斗部分步压装药有限元模拟与实验

Finite Element Simulation and Experimental Study of A Large Caliber Fighting Part of Procedure Press-Load Detonator

为提高大口径弹药分步压装药效率,对某大口径战斗部分步压装药进行有限元模拟与实验。根据分步压装特点制定针对某大口径战斗部的分步压装工艺流程,采用ANSYS有限元模拟方法分析装药过程中弹壁与导爆管与变形受力情况,开展工艺试验制定工艺参数,采用相应的工艺参数进行大口径战斗部分步压装高能炸药。结果表明,装填结果完全满足××大口径战斗部的装药质量要求。

To improve efficiency of procedure press-load detonator about large-caliber ammunition,the fighting part of a certain type large diameter pressure charging finite element simulation and experiment,according to characteristics of procedure press-load detonator establishment of large-diameter warheads for the step flow chart process,use the finite element simulation of ANSYS examine the charge process of wall of shell and detonating pipe by the force,conduct technology test setting down process parameters,using the appropriate parameters for the fighting part of the large-diameter high explosive procedure press-load.The results showed that： loading results meet the charge quality requirements of ×× large diameter warhead.
