摘要
为了研究不同结构的噪声控制装置对聚能装药爆炸的噪声控制效果,设计两种爆炸噪声控制装置,对两种装置进行试验研究。试验表明,封闭式噪声控制结构的噪声控制效果明显优于开孔式噪声控制结构,降噪量平均值分别为22.6%、17.9%,而且两种装置均穿透了40.0 mm厚均质45#钢靶板,对聚能装药的侵彻深度几乎没有影响。
Two kinds of noise control equipments were designed and carried out to investigate the noise control im- pact of two different configurations. It is proved that the noise control impact of the closed noise control equipment is better than that of the open noise control equipment. Their average quanta of noise elimination were 22.6% and 17.9% respec- tively, and beth the shaped charge jets penetrate through 40.0 nun thick 45# steel isotropic target.
