摘要
针对弹药生产线安全生产的需求,提出一种水滴帷幕的防殉爆装置。利用APDL进行编程,实现水滴在水幕区域的随机投放;用Autodyn仿真软件对水滴帷幕的防殉爆效果进行验证;通过对22种工况的分析,发现随单位区域内水滴数量的增加,水滴帷幕的防殉爆效果不断增强,但当水滴到达一定数量后,水滴帷幕对冲击波超压及破片速度的衰减率趋于稳定。结果表明:该水滴帷幕对冲击波超压的衰减率约为63.2%,对破片速度的衰减率约为87.5%,具有良好的衰减效果,在保证安全性的同时提高生产效率。
According to the requirement of safety production in ammunition production line, an anti-sympathetic detonation device of water drop curtain was proposed. APDL is used to program to realize the random throwing of water drops in the water curtain area, and Autodyn simulation software is used to verify the anti-sympathetic detonation effect of the water drop curtain;Through the analysis of 22 working conditions, it is found that with the increase of the number of water droplets in the unit area, the anti-sympathetic detonation effect of the water droplet curtain is enhanced, but wh en the number of water droplets reaches a certain amount, the attenuation rate of the water droplet curtain on the shock wave overpressure and the fragment velocity tends to be stable. The results show that the attenuation rate of the water drop curtain to the shock wave overpressure is about 63.2%, and the attenuation rate to the fragment velocity is about 87. 5%.The water drop curtain has a good attenuation effect, which ensures the safety and improves the production efficiency.
