| 摘 要： | 对V形反应装甲飞板飞散变形的物理过程进行分析,认为V形反应装甲与射流作用过程分流为两个阶段:在中间两飞板碰撞以前,两组件的运动是独立的,按两个单个反应装甲先后与射流作用;中间两板碰撞以后,按射流与单个反应装甲作用计算。借助ANSYS-DYNA对V形反应装甲与射流作用过程进行数值模拟,得到了V形反应装甲与射流作用的物理过程,模拟结果和理论分析与实验基本吻合。

| Abstract: | According to the physical process of flying panel in V-shaped double ERA, the interaction process between jet and double parallel ERA can be devided two phases. Before the collision of the middle panel,the jet can be considered to be interacted with both ERA. But after collision,the jet is considered to be interacted with single ERA. By applying dynamic software ANSYS-DYNA,the physical interaction process between V-shaped double ERA and jet is obtained. The simulation results agree well with the experimenta... |
