摘要小口径火炮是一种攻击目标非常宽泛的武器，具有机动灵活、反应敏捷的特点。30mm口径火炮引信设计时需要考虑冗余保险、延期解除保险、高灵敏度、自毁功能、大着角发火等问题。为了保证引信结构正确、加工工艺性好并且使设计出的引信零件满足互换性要求，在设计中一般采用极值解法引信所涉及到的尺寸链进行计算。为了保证引信系统安全可靠，需要对引信零件强度及引信发火和保险性能进行分析和计算。通过对尺寸链进行分析可知，该引信具有工程设计价值。通过对引信性能分析和计算，该引信安全性和可靠性有保证，符合GJB 373A—1997《引信安全设计准则》的相关要求。68550

Title     Systems Analysis and Design Calculations of    30mm Artillery Fuse                                             

Abstract Small-caliber artillery is a weapon attacks broad targets with flexible and responsive features. The problems such as redundant insurance、delaying arming 、self-destruction function、functioning at high impact angle should be taken into consideration when designing 30mm artillery fuze. In order to ensure the right structure with technology performance and make the designed element of the fuze meet the interchangeability requirements, the dimension chain concerned with the fuze should be calculated according to the extreme value method when designing. To ensure system of fuze safe and reliable, the strength-checking of the element and the security and firing performance should be analyzed and calculated. Analysis of dimension chain   shows the fuze is available for engineering design. Through  performance analysis and calculation, safety and reliability of the fuze are guaranteed， which conforms to the relevant requirements of GJB 373A—1997 《The Safety Criteria For Fuze Design 》.
