摘要:
基于一级轻气炮加载装置,研究了高低温循环及对称冲击耦合加载下某黑索今(RDX)基含Al炸药的安全性,计算了缺陷处的内能等参数。结果表明:高低温循环后,炸药试样出现可见的孔隙。对称碰撞加载后,不经高低温循环的试样未发生点火,应力加载峰值为835 MPa,加载时间为35 μs;而经历高低温循环的试样出现点火,点火前应力为242 MPa,加载时间11 μs。高低温循环所产生的缺陷是导致炸药点火的重要原因。
Abstract:
Safety of RDX-based aluminized explosive under temperature cycle and coupling loading of symmetrical colliding was evaluated by one-stage light-gas gun experiment, and the parameters such as internal energy were calculated. Results show that it has appeared defects of explosive after temperature cycle experiment. Ignition of this explosive with defects occur under the conditions of symmetrical colliding, the loading stress is 242 MPa, and the loading time is 11 μs. While the ignition of explosive without defects will not occur under the same condition, the loading stress is 835 MPa, and the loading time is 35 μs. Defects caused by temperature cycle are the main reasons for ignition.
