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.
