Fragments Loading Properties of Warship Bulkhead from Moving Fragmentations Kill Warhead

doi:10.3969/j.issn.1000-1093.2019.09.006

Abstract

Abstract: On the basis of empirical formulas about mechanics of explosion and several reasonable assumptions, a space coordinates system of moving fragmentations kill warhead and target bulkhead was built, and a simple and practical mathematical model was deduced. The mathematical model is programmed with MATLAB program language in order to further understand the effect of initial warhead kinestates, including warhead position, attitude angle, planar motion, and rotational motion, on fragment loading acting on bulkhead, in which the target impact position, total mass of impacting fragments and expected value of impact velocity on each divided bulkhead surface are estimated. The calculated results show that the initial position, attitude angle and planar motion of warhead have major effects on the loading properties, while the rotational motion of warhead has an unremarkable effect on the fragment loading, and the root cause of aforementioned effect rules is the difference of fragments kinetic characteristics.
