impacting pin
解釋
撞擊銷-
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
對底- 9底火、底部被擊針撞擊后的第- 9底火和底- 5底火在膛壓作用下分別進行了有限元數值分析，計算表明： （ 1 ）底- 5底火底部擊針撞擊部位為火帽座，其材料為鋼帶，底- 9底部承受撞擊部位為底火體，其材料為冷拉退火圓鋼，由於材料強度不同，承受壓力能力和變形能力不同：雖然在膛壓作用過程中底- 5底火的最大應力值比底- 9底火的大，但底- 5底火的最大位移量卻比底- 9底火的小得多。
