3) unsymmetrical spring
不对称的弹簧钢板
4) a perforated steel plate; perforated cancellation; perforated stamp.
穿孔钢板;打孔作废;打孔邮票。
5) punched steel plate
穿孔钢板
6) APP
穿甲子弹
1.
Simulation Study on Ceramic/Mild Steel Targets Penetrated by APP
穿甲子弹侵彻陶瓷/钢靶板的数值模拟研究
2.
Optimization of two-layer ceramic/metal composite targets against ballistic impact by Armor Piercing Projectile(APP) was investigated.
62 mm穿甲子弹,Florence模型精度较好,本文计算结果与试验结果吻合较好。
3.
Based on the mechanisms of ceramic composite target against APP(amour-piercing projectile), an approximation to the deformation and cracking of ceramic composite target\'s back plate was proposed, in which the impact action of APP onto the back plate through ceramic cone was equated with truncated-cone-shape localized impulsive load.
基于陶瓷复合靶板抗穿甲子弹机理,将弹丸通过陶瓷锥施加于背板的冲击作用等效为截锥形局部冲击荷载,提出一种计算背板变形和起裂的新方法。
补充资料：子弹
1.即枪弹。又弹壳﹑底火﹑发射药﹑弹头四部分组成。发射时由撞针撞击底火，使发射药燃烧，产生气体将弹头推出。
