摘要

摘要: 在推广的Gurney理论模型基础上，采用遗传算法优化技术，对平面二级强爆轰驱动非线性问题进行了初步的优化设计。飞片及炸药的材料分别为钢及JO-9159，在初级飞片和次级飞片厚度分别为2.5 mm和0.5 mm时，得到了不同初级飞片速度（5.0～6.5 km/s）下次级飞片的最大速度及对应的次级炸药最佳厚度。并对铝、铜、钼及钽等几种典型金属材料飞片进行了计算，得到了初级飞片速度为5 km/s时对应的次级炸药最佳厚度等优化参数。这些计算结果可以为二级强爆轰驱动装置的实验设计提供重要参考。

Abstract: Based on the improved Gurney model for explosive acceleration, a planar two-stage strong detonation driving device has been optimized with genetic algorithm. The flyer and the explosive are steel and JO-9159, and the thicknesses of the first and the secondary flyer are 2.5 mm and 0.5 mm, respectively. The maximal velocity of the secondary flyer and the optimized thickness of the explosive are obtained at different velocities of the first flyer from 5.0 km/s to 6.5 km/s. In a similar way, the optimized parameters are also obtained when the flyer's material is aluminium, copper, molybdenum and tantalum, respectively, with a initial velocity of the first flyer of 5.0 km/s. The calculation results can be used in experimental design of planar two-stage strong detonation driving device.
