摘要:

采用六硝基芪域( HNS域) 微爆索切割航空有机玻璃( PMMA) 板。在改进的实验装置上,针对3 种不同长度的PMMA 板材,在3 种不同温度下,完成了45 次微爆索爆炸切割PMMA 板实验,研究温度、尺寸和边界约束对切割效果的影响。实验结果表明,在所研究的范围内,温度、尺寸和边界约束条件对爆炸切割PMMA 板的效果影响甚微,可以忽略不计。因此,元件的实验参数和结果,可以直接用来指导真实件实验,为弹射救生系统的设计和改进提供科学依据。

Abstract:

Miniature detonation cord (MDC) with HNSII is used to cut aerial PMMA plate. 45 experiments of MDC cutting PMMA plates with three different lengths are performed at three different temperatures on a modified test apparatus. The effect of temperature, size and boundary condition on cutting results is investigated. Experimental results indicate that these factors, such as temperature, size and boundary condition of PMMA plate studied in the paper, have a slight effect on the cutting results, which can almost be neglected. Consequently, the cutting canopy experiment is directly guided by component experimental parameters and results, which provides science foundation for the design and improvement of ejection-lifesaving-system.

Key words: explosion mechanics, ejection-lifesaving-system, MDC, explosion cutting, PMMA
