摘要
用有限元模型分析了激光辐照下金属／炸药双层材料的温度分布，得到了炸药表面中心温升与激光强度、光斑尺寸以及激光作用时间的关系，还得到了激光对金属／炸药装置点火的初步规律，分析了亚音速气流的对流换热对靶面温度场的影响。
A finite element model is used to analyze the temperature distribution of metal/explosive di layer materials irradiated by laser. The temperature rise of explosive surface center varying with laser intensity, spot size, and irradiation time is given. The preliminary results about laser ignition on explosive with a metal envelope are got. The subsonic airflow convective heat transfer influence on the target temperature field is also analyzed .
