摘要针对某子母弹子弹引信在可靠性以及安全处理问题上仍存在着一些缺点，对改进后子弹引信进行了系统分析、强度校核和性能计算，使改进后子弹引信符合要求。通过对引信外壳和引信体的强度计算，以及子弹系统内的弹簧等薄弱单元进行校核，使子弹引信结构强度符合要求。通过对子弹引信的后坐保险性能、离心保险性能、滑块部件启动条件、反恢复销作用正确性进行性能计算，以确保子弹引信的保险和作用可靠。此外对自毁发火装置进行了性能计算，对子弹引信的平时安全性进行评估，同时对运动击针刺发组合延期管进行能量计算。结果表明，改进后的子弹引信强度满足要求，能够保证后坐保险、离心保险和滑块等作用可靠，平时安全性、自毁性能良好。结果表明，该引信能可靠解除保险，发火可靠，具有触发和自毁功能；满足弹丸总体要求。21390

Title Systems Analysis and Design Calculations for a kind of Submunition Fuze of Multifunction Cargo Projectile
Abstract
For a submunition fuze reliability and security in handling problems, there are still some shortcomings, conducted after improved the submunition fuze system analysis, performance calculation and strength check. Through the strength of the shell and fuze fuze body calculations, as well as the submunition within the system, such as a weak spring unit checked to make submunition fuze structural strength to meet the requirements. By sitting on the submunition Insurance fuze performance, safety performance centrifugal slider parts start condition, the role of anti-restore-off performance calculations correctness to ensure reliable insurance and the role of submunition fuze. In addition to self-destruct ignition device for calculating the performance of the submunition fuze usually assess safety, while the strike movement combination of acupuncture hair extension tubes for energy calculations. The results show that the improved strength of the submunition fuses meet the requirements, to ensure recoil insurance, such as the role of the centrifugal insurance and sliders reliable peacetime security, self-destruct good performance. The results show that the fuze arming reliable, angry reliable, trigger and self-destruction; meet the overall requirements of the cargo projectile.
