摘要

为确立柱形战斗部破片侧向飞散参量的可靠计算模型,结合试验数据对现有破片初速和抛射角模型进行分析和评价;总结了战斗部长径比、壳体破裂半径、空心装药结构、破片种类和偏心起爆等因素对破片初速的影响;对比了三类常用的初速轴向分布模型,表明修正的冲量模型有最好的表征效果;总结并分析了破片抛射角的三种模型,基于周培基模型构建了一种新的精度较高的破片抛射角模型。

Abstract

In order to establish the reliable calculation model of cylindrical warhead lateral scattering parameters, combined with the test data, the existing fragments initial velocity and projection angle were analyzed and evaluated. Firstly, the influence of draw ratio, shell rupture radius, hollow charge structure, fragment type and eccentric initiation of warhead on fragment initial velocity was summarized. Secondly, three types of frequently-used axial initial velocity distribution model was compared and it was indicated that the modified model had the best characterization effects. Thirdly, three models of fragments projection angle were summarized and analyzed, and a new fragments projection angle model with higher precision was set up based on Zhou Peiji model.

Key words： high explosive warhead; fragment initial velocity; projection angle
