基于外弹道模型的导电纤维丝束落点散布研究

Study on Point Dispersing of Conductive Fiber Based on Exterior Ballistic Model

为研究短路毁伤元-导电纤维丝束的落点散布规律,根据子母弹抛撒外弹道理论和丝束展开及飘落运动特性,并重点考虑到丝束运动过程中抛撒速度的散布对其落点的影响,建立了丝束从抛撒到落地的外弹道模型.通过蒙特卡洛法选取丝束抛撒过程中的抛撒速度并代入模型进行了求解.计算结果表明,丝束散布范围、散布半径等参量与飞行试验结果基本吻合,证明了本模型具有应用参考价值.

Abstract. An exterior ballistic model of the conductive fiber cluster, which includes stages from dispersing to falling to the ground, was presented to study on the point-dispersing law of the cluster. The model was based on dispersing exterior ballistic theory of submunitions and moving character of the fiber cluster. In particular, the influence of dispersion of dispersing velocities was considered. Besides, Monte Carlo method was applied to select the dispersing velocities to solve the model. Simulation results of spreading range and radius of the fiber clusters are consistent with the flight test, which proves the application reference value of the model.
