摘要

半穿甲弹爆炸产生的高速破片侵彻性能优劣直接决定了武器毁伤效率

而破片形成时的温度升高会对其侵彻性能产生直接影响

因此有必要研究破片温升对其侵彻性能的影响

为提高破片毁伤能力提供参考。从能量的角度推导了炸药爆轰使破片温度升高的理论计算公式

模拟圆柱形弹体爆炸形成破片过程

得到了破片的速度和温度载荷特性

采用有限元分析软件模拟不同温度破片侵彻不同厚度钢靶过程

通过对数值模拟结果进行分析

得到了破片温度对钢靶侵彻性能的影响规律。研究发现:大部分破片温度在525K左右

远端部破片温度较高

可达到800K以上;当靶板厚度为3~8mm时

侵彻同厚度靶板

破片温度越高

剩余速度整体趋势增大

表明高温破片会牺牲掉前半部分的质量使得剩余部分破片仍留有相对较高的速度;破片温度越高

贯穿靶板时所需要的速度越大

消耗的能量也越多

即破片侵彻性能降低。

Abstract

The penetration performance of the high-speed fragments produced by the explosion of semi-armor-piercing bullets directly determines the destructive efficiency of the weapon.The increase in temperature during the formation of fragments has a direct impact on its penetration performance.Therefore

it is necessary to study the influence of the temperature rise of fragments on its penetration performance to provide a reference for improving the destructive ability of fragments.In this paper

the theoretical calculation formula for the increase in fragment temperature caused by explosive detonation is derived from the perspective of energy.The process of a cylindrical projectile forming the fragments during explosion is simulated

and the velocity and temperature load characteristics of the fragments are obtained.The finite element analysis software is used to simulate the processes of fragments with different temperatures penetrating the steel targets with different thicknesses.The influence law of the fragmentation temperature on the performance of fragments penetrating the steel target is obtained through the analysis of the numerically simulated results.The research finds that the temperatures of most fragments are around 525K

while the temperatures of the distal fragments are relatively high

which can reach above 800K.When the fragments penetrate 3mm-8mm-thick target plate

the higher the temperature of the fragments

the overall trend of the remaining velocities of fragments increases with the increase in the temperatures of fragments

indicating that the high-temperature fragments will sacrifice the mass of the first half to result in the remaining fragments still having a relatively high velocity.The higher the temperature of fragment is

the greater the speed required to penetrate the target plate is

and the more energy is consumed

that is

the penetration performance of the fragment decreases.
