击针 meaning in Chinese
firing pins
Examples
- The results proved that : ( 1 ) because of the material ' s difference of primer - 9 and primer - 5 , the maximum stress of primer - 5 is larger than primer - 9 but the maximum displacement is smaller than primer - 9 . ( 2 ) because of the unrenewable shape changing of primer - 9 after impacting by the pin , it will cracking under high pressure more easily . so , the paper give the suggestion that the designer should decrease the depth of impacting by pin in the case of the primer be fired successfully
对底- 9底火、底部被击针撞击后的第- 9底火和底- 5底火在膛压作用下分别进行了有限元数值分析，计算表明： ( 1 )底- 5底火底部击针撞击部位为火帽座，其材料为钢带，底- 9底部承受撞击部位为底火体，其材料为冷拉退火圆钢，由于材料强度不同，承受压力能力和变形能力不同：虽然在膛压作用过程中底- 5底火的最大应力值比底- 9底火的大，但底- 5底火的最大位移量却比底- 9底火的小得多。
