155mm口径火炮区域封锁子弹及其引信设计

摘要在现代战场上，坦克防护能力的提高主要集中在正面、侧面和炮塔位置，而对坦克底甲和履带的防护却没有大的提高。据此设计 155mm 炮射子母弹的子弹，该子弹实现对坦克底装甲的最大毁伤。其战斗部采用自锻破片战斗部（EFP）；引信采用磁感应近炸引信，还包括传爆序列、滑块隔爆机构、冗余保险装置、反恢复保险装置等组成。为了得到弹道末端子弹抛撒时转速，对弹道进行计算；为了保证引信结构设计的正确性，对引信强度校核；为了保证引信保险可靠性和解除保险可靠性；进行弹簧及其零部件的校核；为了得到子弹最终落地姿态，对子弹进行落姿的模拟仿真。通过设计计算，结果表明，子弹及其引信设计能够满足设计的总体要求。 69544

Title Area denial bomblet and it's fuze design used in 155 mm caliber gun

Abstract

In the modern battlefield, tank protection ability enhanced mainly in the front, side and turret position, but on tanks bottom wasn't big improvement. Based on what the above mentioned to design 155mm gun fired bomblet, which let tank's belly armor to achieve maximum damage. Explosively-Formed Projectile (EFP); magnetic detection proximity fuze, also includes the booster sequence, redundant and other components. In order to get the rotating rate of the end of the ballistic trajectory, through calculation of the trajectory; in order to ensure the correctness of the fuze design, the intensity of fuze be checked; in order to ensure the reliability and safety fuze arming reliability, spring, parts and components to be checked; in order to obtain a final bomblet landing attitude, simulation the attitude of the bomblet falling. Through the design calculation, that the design of the bomblet and its fuze can meet the requirements of the design.
