一种适用于子弹药引信的预储能 离心作用机构的设计与分析

针对联合国对子弹药未爆弹率及功能的要求,结合国内子弹药引信的发展现状,提出了对原有子弹药引信进行机械结构改进的方案。结合子弹药引信的结构特点及其工作环境特点,设计了一种预储能离心作用机构,并对其作用原理和作用过程进行了详细阐述。对该机构进行受力分析,按子弹药工作过程分阶段对其进行了可靠性计算和动力学仿真。计算和仿真结果表明,预储能离心作用机构能够可靠作用,达到了设计目的。     

Design and analysis of mechanical self-destruction and self-neutralization mechanism for submunition fuze

In order to decrease the unexploded submunition rate and reduce the harmfulness of unexploded submunition, a mechanical self-destruction and self-neutralization mechanism for submunition fuze is proposed in this paper. The definitions of the self-destruction and self-neutralization for submunition fuze are elaborated, and the action principle of the mechanical self-destruction and self-neutralization mechanism is also analyzed. A dynamic model is established with an analysis on centrifugal plate parts, and the feasibility of mechanism motion is also discussed. A virtual prototype of mechanism is formed, and the motion process simulation of the mechanism is performed through a dynamic analysis software ADAMS. The centrifugal experiment results validate that the mechanical self-destruction and self-neutralization mechanism can act reliably.
