子弹撞击下CL-20基PBX装药响应研究
Response of CL-20 based PBX charge under bullet impact
摘要
Abstract
To improve the warhead impact safety and guide the design and application of a typical warhead filled with CL-20 based PBX,the research on the response characteristics of the typical warhead under impact is carried out based on bullet impact tests.The bullet impact test is conducted and the reaction level of the warhead impacted by a bullet is evaluated by analyzing the overpressure data,holes punched on the witness board,video of the test,and the recovered sample.The result shows that the warhead reacted to the detonation level under the impact of a bullet with 836 m/s.Moreover,the numerical simulation on the impact safety of the warhead under different conditions is carried out to research the reaction process of the warhead under different velocity impacts.The result shows that the warhead respectively react to the detonation and combustion level under the impact of a bullet with 850 m/s and 750 m/s.This work provides data support for the prediction of impact response and evaluation of reaction level of the typical warhead.关键词
