摘　　要：针对柱形杆条的爆炸驱动机理研究,应用数值模拟软件AUTODYN-2D对柱形杆条的不同结构及排布参数进行分析,研究了杆条爆炸驱动的流场压力及速度变化规律。研究表明,杆条排布结构的介质层类型及厚度、装药厚度及排布间隙均对杆条的驱动冲击载荷、速度及相邻速度差有较大影响。该研究可为相关爆炸驱动问题研究及结构设计提供参考。Focused on explosively driven prineiple of cylinder, the numerical simulation software AUTODYN -2D was utilized to analyze structures and parameters of the cylinder, the explosively driven flow field pressure and vibrating regularity were studied. The result shows that there is significant effect of medium type and thickness, charge thickness and clearance on driven impact load, velocity and adjacent velocity difference of the cylinder. The study can be applied to explosively driven structural design.
