摘要该设计适用与弹底惯性发火引信,目标是使目标引信具备较高的弹道安全和可靠的擦地炸功能。主要设计思路为通过区分弹丸所处的外弹道阶段,让引信的发火机构产生结构上的变化,从而兼顾弹道安全性和擦地炸的灵敏度。69442
为了做好相关的设计要求,分析了国外的典型的弹底引信,并做了相应的归纳总结。在此基础上对105mm坦克炮弹引信的主要战术指标及性能要求进行了系统分析,确定了机械、机电两种引信设计方案。机械引信的隔爆机构采用了水平转子隔爆,保险机构采用后坐保险加上离心保险。做出了机械引信的部分零件图。引信的安全性符合GJB373A-1997《引信安全性设计准则》和GJB 573A-1998《引信环境与性能试验方法》的相关要求。

Title Tank shells explode and wipe drug fuze ballistic safety compatibility design
Abstract The design is suitable inertia and elastic bottom Ignition fuze, fuze goal is to target a higher trajectory safe and secure wiping fried function. The main distinction between the projectile design ideas through which foreign ballistic phase, so that the fuze firing mechanism produces structural changes, which take into account the safety and ballistic wipe fried sensitivity.
In order to make the relevant design requirements, analysis of typical Base Fuze abroad, and made the corresponding summarized. On this basis, the main tactical indicators and performance requirements 105mm tank shells fuse on a systematic analysis to determine the mechanical, electrical fuse two designs. Mechanical fuze explosion proof mechanism using the horizontal rotor, after sitting Insurance Insurance agencies use plus centrifugal insurance. Made mechanical fuze some parts Fig. Fuze security compliance GJB373A-1997 "Fuze safety design guidelines" and GJB 573A-1998 "Fuze Environment and performance test method" requirements.
