摘　　要：针对聚能弹集装储运意外爆炸条件下的殉爆问题,应用脉冲X光成像技术,分别对某型聚能弹射流在空气中自由成型及运行过程,不同材料干扰装置作用于射流成型的过程进行X光拍摄试验,获得射流未被干扰状态的基本参数和在不同材料干扰装置作用下的干扰效果X光影像,并在影像分析基础上,研究干扰装置的作用机制,为提高干扰装置的射流防护性能,提供基础试验数据。结果表明：试验用聚能弹的射流准直性良好,在54~197.4 mm炸高范围内具有较强的侵彻能力,防护困难;3种材料的干扰装置对射流成型过程都发挥显著抑制作用,射流均未成型;干扰装置的作用机制主要是施加干扰后,药型罩的受力状态发生明显改变,干扰装置使药型罩变形受阻,变形速度显著降低,最终未形成射流;强度较高、密度较大、较耐高温的材料干扰效果较好。With regard to the induced detonation feature of shaped charge after accidental explosion in packaging and transportation process, pulsed X-ray imaging technology is applied to have X-ray photographing test on the free forming and moving process of the jet flow of one type of shaped charge in air and the process that jamming device of difference materials acts on the jet formation. Through the test, basic parameters under the condition that the jet flow is not interfered and the X-ray image of interfering effect of jamming devices of different materials are obtained. In addition, the acting mechanism of jamming device is studied on the basis of image analysis to provide data in basic test for the improvement of jet protection performance of jamming device. Results show that the shaped charge for test has good jet alignment and it has strong penetration ability within a burst height ranging 54 to197.4mm; jamming devices of three materials have obvious effects in restraining the jet formation and the jet formation always fails; the acting mechanism of jamming device is that after an interference is posed, the stress state of shaped charge liner will change obviously, the jamming device will deform and restrict the liner, the deformation speed will be decreased obviously and finally jet will not be formed; material with strong strength, large intensity and great high temperature resistance has good interfering effects.
