摘要: 采用分子动力学方法对旋转圆筒内黑索今和铝二元颗粒体系进行模拟.模拟结果表明,混合均匀度与填料方式无关.当圆筒壁无挡板时,圆筒的旋转可以使黑索今和铝颗粒发生相分离现象,当有挡板时,可以增加混合效应.另外,对上述混合与分离现象给予了一定的理论解释.

关键词: 炸药, 混合, 分子动力学模拟

Abstract: Molecular dynamics is used to simulate binary granular of RDX and Al in a revolving drum.It shows that mixing quality is irrelative with filling method.In a drum without baffle plate on the wall,segregation of RDX and Al granule happens due to revolution of drum.With an added baffle plate on the drum wall,mixing effect is increased.Theoretical explanation is given for mixing and segregation.

Key words: explosive, mixing, molecular dynamics simulation
