摘要现代战场上，为了将弹药对目标的毁伤作用最大化，许多国家越来越多地生产、使用 子母弹药。随着一系列限制使用集束弹药的公约签署，子弹引信的设计被要求必须引入自 毁、自失效、自失能功能。此子弹引信构造上由发火机构、隔爆机构、保险机构、自毁机 构等组成。为了保证结构可靠性，通过计算对引信零件以及工作状态进行校核；为了保证 发火机构和自毁机构的可靠性，对弹簧强度进行了校核；为了保证装配正确性，对零件以 及装配部件进行了尺寸链计算。理论计算结果表明，该子弹引信在发射和弹道环境中能正 常工作，在没有命中目标时能自毁，满足国际公约的要求。此引信采用纯机械结构，性能 稳定可靠。69547

Title The analysis and design of submunition fuze fired with  artillery that meet the international convention

Abstract

In the modern battlefield, in order to make the target damage effect maximization, many countries are increasingly producing and using the shrapnel. With a series of convention on the use of cluster munitions signed, submunition fuze design has been asked to introduce self-destruction, self-destroy, self- disability devices. This submunition fuze meet the international  convention. It consists of initiation mechanism, arming device, interrupter device, self- destruction device, etc. In order to guarantee the reliability of the structure, necessary calculation of the fuze was made; In order to guarantee the reliability of the initiation mechanism and self-destruction device, the strength of the spring was checked; In order to ensure the assembly accuracy, the dimension chain calculating parts and assembly parts was checked. The theoretical calculation results show that the submunition fuze in emission and ballistic environment can work normally, and realized reservation function, meet the requirements of international conventions. It uses pure mechanical structure, and is reliable in performance.
