摘要
为研究某种注塑成型PMMA材料的爆炸切割特性,通过聚能切割索爆炸切割PMMA靶板试验得到最佳炸高范围,并结合工程实际进行多介质情况下的靶板切割试验,同时利用有限元仿真进行模拟计算.研究结果表明,随着炸高的增加,聚能切割索对PMMA靶板的侵彻能力先增大后减小,最佳炸高范围为1.5～3.0 mm;PMMA靶板爆炸切割的断裂主要由射流侵彻作用及层裂作用引起,其中射流侵彻作用占比约为56.5％,层裂作用占比约为43.5％.
Abstract
In order to study the explosive cutting characteristics of a certain injection molded PMMA material,the op-timal range of explosion height was obtained through linear shaped charge explosive cutting PMMA target plate experi-ments.Combined with engineering practice,target plate cutting experiments were carried out under multi medium condi-tions,and simulation calculations were conducted using finite element simulation.The research results indicate that as the ex-plosion height increases,the penetration ability of linear shaped charge to PMMA target plate first increases and then de-creases,and the optimal explosion height range is 1.5～3.0 mm;The fracture of PMMA target plate during explosive cutting is mainly caused by jet penetration and spallation.The proportion of jet penetration is about 56.5％,and the proportion of spallation is about 43.5％.
