摘　　要：为深入研究在膛内最大压力作用下,活塞式驱动机构驱动丝团抛撒的运动特性,以及丝团在膛内运动规律,推导建立了丝团膛内运动的弹道模型。以MATLAB数值计算软件为基础,基于四阶龙格库塔算法编写相应的计算程序对模型进行数值求解。进一步通过靶场试验对丝团出膛口速度进行测量,获得的试验结果与数值计算结果吻合程度较好。结果表明计算模型的合理性,可以为深入设计驱动结构及优化丝团散布特性提供参考。In order to further study of piston driving mechanism drivers the silk cluster scatters movement characteristics and silk cluster movement rule in the bore,a ballistic model of silk cluster in the bore movement was set up. Base on the numerical calculation software of MATLAB,forth-order Runge-Kutta algorithm was used to solve the model. By shooting range test on soft damage silk cluster out of the chamber outlet speed measure,and the numerical calculation results are consistent with the experiment results,which proves that the model is reasonable.Numerical calculation and experimental results provides reference for determining optimal performance and requirements of silk cluster reasonable distribute density,provides reference for operational performance indicators.
