摘　　要：为研究乙烯-醋酸乙烯酯共聚物(EVA)对RDX基含铝炸药性能的影响,在A-IX-II炸药中添加EVA制备了含铝PBX炸药。用分子动力学(MD)方法计算了黏结剂EVA与A-IX-II炸药各组分的结合能以及作用方式、AIX-II炸药及含铝PBX炸药的力学性能。计算结果表明,EVA与A-IX-II炸药各组分的结合能均大于0,相互作用力以范德华力为主;EVA能够显著提升A-IX-II炸药的力学性能,使其弹性模量从20.58GPa升至33.27GPa。对A-IX-II炸药和含铝PBX炸药进行了静态力学性能试验,计算结果与试验结果一致性较好。In order to study the effect of the copolymer of ethylene and vinyl acetate （EVA）on the performance of RDX based aluminized explosive.The A-IX-II explosive and aluminized PBX explosive were prepared.The binding energy and the interaction mode between EVA and components of A-IX-II explosive and the mechanical properties and sensitivity of A-IX-II explosive and aluminized PBX explosive were simulated by the molecular dynamics method.Simulation results show that binding energy between EVA and each component of A-IX-II explosive is greater than 0 and EVA interacts with each component of A-IX-II explosive mainly in van der Waals force.The mechanical properties of A-IX-II explosive significantly increase by adding EVA and the elastic modulus of A-IX-II explosive increases from 20.58 GPa to 33.27 GPa.The static mechanical performance tests for A-IX-II explosive and PBX were proceeded.The calculated results agree well with the experimental ones.
