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、A-IX-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20．58 GPa 升至33．27 GPa。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.
