The one-dimensional problem of the motion of the rigid plate under explosive attack has an analytic solution only when the polytropic index of detonation product equals to three. In general, a numerical analysis is required. In this paper, however, by utilizing the "weak" shock behavior of the reflection shock in the explosion product, and applying the small parameter purterbation method, an analytic, first-order approximate solution is obtained for the problem of flying plate driven by various high explosives...

The one-dimensional problem of the motion of the rigid plate under explosive attack has an analytic solution only when the polytropic index of detonation product equals to three. In general, a numerical analysis is required. In this paper, however, by utilizing the "weak" shock behavior of the reflection shock in the explosion product, and applying the small parameter purterbation method, an analytic, first-order approximate solution is obtained for the problem of flying plate driven by various high explosives with polytropic indices other than but nearly equal to three. Final velocities of flying plate obtained agree very well with numerical results by computer. Thus an analytic formula with two parameters of high explosive (i. e. detonation velocity and polytropic index) for estimation of the velocity of flying plate is established.

刚性飞片在炸药爆炸作用下的一维抛掷问题,仅当爆炸气体多方指数等于三时可以求得解析解;一般情况下须利用计算机求出数值解本文利用了爆炸气体中反射冲击波的“弱”击波特性,使飞片运动和飞片后方流场之间相互耦合的复杂问题解耦而归结为求解常微分方程问题;然后用小参数摄动法求出多方指数接近于三的各种炸药驱动飞片问题的近似解析解,所得飞片终速和数值解符合很好;从而给出了用爆速和多方指数等两个炸药示性参量表出的估算飞片运动的良好近似公式.

The measuered velocities of flyers driven by explosives with differer thicknesses are compared with the results calculated by our CHD 82 one-dimentional reactive hydrodynamic code. The results show that the so-called "effective CJ pressure",as proposed by Craig et al,does not influence the explosive peformance for driving flyer and that the characteristic parameteters in equation-of-state which are applicable to a thick explosive can be used in calculculating the thin explosive as well.

The geometry configuration of the switch is a stripe. The explosive forming technique was employed to design the switch in which an aluminum impacter(cathode) driven by a special explosive assembly, areal velocity synchronistically hits and cuts the insulator. then is embedded into the slot of another electrode to form a secure con- tact.

A type of high explosive-driven closing switch has been developed for crowbar in electromagnetic railguns or other intense current operating devices. The geometry configuration of the switch is a stripe. The explosive forming technique was employed to design the switch in which an aluminum impacter(cathode) driven by a special explosive assembly, areal velocity synchronistically hits and cuts the insulator. then is embedded into the slot of another electrode to form a secure con- tact. The measurements show that its puncture voltage>30kV. inductance (including transmission line)<50nH, peak current 400kA, contact resistance much less than 0.lm Ohm, and the acting time about 14μs. The ID and 2D numerical calculations were carried out to simulate the detonation impact and deformation process in the switch. An empirical model to describe the switch resistance time-dependance has been proposed, using which the numerical simulation of the railgun system performance is completed and accordant with the experimental data well.

由于电磁轨道炮和其它强电流装置中短路运行的需要,研制了一种条形炸药驱动的大电流闭合开关。利用爆炸成型技术使金属飞板负电极在炸药部件作用下,大面积地同时切断绝缘薄膜,嵌入另一电极模槽中构成牢固的接触。开关的绝缘强度大于30kV,电感(包括传输线)小于50nH,最大峰值电流达到400kA,闭合接触电阻小于0.1mΩ,动作时间约为14us。对于开关的爆轰,撞击及变形过程进行了一维和二维数值模拟计算,并提出了一个描述爆炸开关行为的经验模型。利用这个模型进行电磁轨道炮整个系统的数值模拟,同实验结果符合较好。
