金属箔电爆炸驱动飞片模型的设计及应用 总被引:1,自引:0,他引:1
在研究电爆炸过程中桥箔非线性电阻变化的基础上,得到了一种描述桥箔电功率变化的理论计算模型。根据LLNL测量飞片速度的部分实验结果,估算出桥箔用于驱动飞片做功能量占桥箔吸收总能量的比率,即爆发前β1≈9.9×10^-3爆发后β2≈8.6×10^-3.把带有能量转换系数的电功率计算模型应用到流体动力学程序,并对电爆炸驱动小尺寸飞片的飞行历程进行了一维数值模拟,模拟结果与LLNL实验值的偏差在±8%以内,与国内用VISAR测量的飞片速度历程吻合得较好。 相似文献

In order to improve the power of initiating explosive warheads,besides exploring new type of high explosive,multipoint initiation technology becomes the research focus.With research on electronic safety and arming devices(ESADs),pulse power devices and slapper detonators,a hardware control circuit was designed for multipoint initiation control system based on complex programmable logic device(CPLD).In addition,a real-time monitoring interface based on virtual instruments technology was designed by the prevailing software of Laboratory Virtual Instrument Engineering Workbench(LabVIEW).It provides users a real-time status of the hardware circuit system.Moreover,a series of experiments were done on the software and hardware platform.The results show that the signals transmission,collection,analysis and display can be realized reliably through a serial port line.It is verified that using a serial bus controller for multiple initiators is reasonable.Successful design of the platform will play an important foundation for the theory and engineering of the future weapon system.Surely,it will become one of the development directions for intelligent initiation system. 相似文献
