The safety theory on the warhead under launching is a interesting subject in the weapon science. The stress state in the charge medium of a warhead under launching is a key question to be studied. It is very difficult to measure local stress in a warhead under launching. There have not been any better measurement technique and results until now. We investigated the dynamical response of the charge medium in a warhead under launching by numeral simulation and mechanical analysis. This work became a theoretic base for the use of thermo-baric warhead. The obtained results show that the stress states in charge medium in the low and middle parts are pressurized mostly in the launching history. The instantaneous void will appear between the top end of charge and the shell of warhead. This is because the stress wave velocity in the shell is larger than that in the thermo-baric charge medium. This instantaneous void may be a risk for explosion of charged thermo-baric explosive in a warhead under launching.

发射载荷下战斗部的安全性理论是武器研究领域中的重要课题。通过发射过载数值模拟、力学分析,对温压药剂在发射过载条件下的响应规律进行了探索,为温压药剂应用于过载发射武器平台奠定理论基础。研究结果表明,发射载荷在战斗部底部和中部装药内产生的应力以压缩为主,由于战斗部壳体与温压装药的物理力学特性参数相差很大,壳体内的波速远大于温压装药的波速,因此在装药与壳体顶部的分界面处可能出现瞬时间隙,成为发射过程中出现早炸的“危险源”。

发射载荷下战斗部的安全性理论是武器研究领域中的重要课题。通过发射过载数值模拟、力学分析,对温压药剂在发射过载条件下的响应规律进行了探索,为温压药剂应用于过载发射武器平台奠定理论基础。研究结果表明,发射载荷在战斗部底部和中部装药内产生的应力以压缩为主,由于战斗部壳体与温压装药的物理力学特性参数相差很大,壳体内的波速远大于温压装药的波速,因此在装药与壳体顶部的分界面处可能出现瞬时间隙,成为发射过程中出现早炸的“危险源”。

The safety theory on the warhead under launching is a interesting subject in the weapon science. The stress state in the charge medium of a warhead under launching is a key question to be studied. It is very difficult to measure local stress in a warhead under launching. There have not been any better measurement technique and results until now. We investigated the dynamical response of the charge medium in a warhead under launching by numeral simulation and mechanical analysis. This work became a theoretic base for the use of thermo-baric warhead. The obtained results show that the stress states in charge medium in the low and middle parts are pressurized mostly in the launching history. The instantaneous void will appear between the top end of charge and the shell of warhead. This is because the stress wave velocity in the shell is larger than that in the thermo-baric charge medium. This instantaneous void may be a risk for explosion of charged thermo-baric explosive in a warhead under launching.
