| 中文摘要: |
| 传统爆炸膨胀环实验装置采用两端点起爆,爆轰波对碰后加载驱动器的方式,出现试样环加载后侧向翻转、实验重复性差等问题。本文改进传统爆炸膨胀环实验装置中的起爆方式,研制了一种新型爆炸膨胀环实验装置。新起爆方式采用轴心爆炸丝同步线起爆,在驱动器内形成理想的柱面冲击波,有效避免了试样环受冲击后发生侧向翻转,实现了金属试样环的稳定拉伸加载,实验效率得到大幅提高。 |
| 英文摘要: |
| Traditional experimental device for explosively loaded expanding ring utilizes detonator initiation at both ends and loads the driver by head-on collision of two detonation waves. This loading method has some chief shortcomings, such as lateral flip of sample ring after loading and poor experimental repeatability. To effectively avoid above-mentioned problems and improve the loading method of traditional experimental device, an axial wire synchronous initiation was adopted, which produces ideal cylindrical shockwave in the driver. Stable tensile loading for metal sample ring is achieved and experimental efficiency is enormously improved, based on this new loading method. |
