摘要
采用了有限元方法对有机玻璃中长径比L／D=20的黑索金条形药包爆炸速度场进行了数值计算，分析了条形药包爆炸速度场衰减规律。结果发现数值计算值与试验结果相吻合。
The particle velocity field of the cylindric charge exploding in PMMA with the lenth to dimeter ratio of 20 is computated by adopting finile element emthod and its atteruation rule is analysed. The result is that values on the Numerical computation tally with that of testing.
