摘　　要：通过实验和模拟相结合的手段,对LLM-105基混合炸药的组分进行了优化。数值模拟结果表明:3种聚合物粘结剂FJ-1、FJ-2、FJ-3对LLM-105(011)晶面的吸附能分别为-339.6、34.3及57.5kJ/mol,结合密度、成型性及粘结剂的耐高温性能,选择FJ-2作为黏结剂;结果表明:固定黏结剂为FJ-2,用Type3立方多面体晶型的LLM-105单质制备的造型粉的松装密度、成型密度显著大于Type1、Type2晶型制备的造型粉的松装密度、成型密度。多面立方状的LLM-105基混合炸药在成型密度为1.763g/cm的条件下,爆速为7743m/s,相比S992、Y971,爆速分别提升了12.56%及13.22%。By means of combine experiments and simulations,components of LLM-105 based composite explosive were optimized.Simulation results showed that the adsorption energy of those three polymer binder FJ-1,FJ-2,FJ-3to LLM-105were-339.6,34.3and 57.5kJ/mol.Considered combined with density,moldability and high temperature resistant properties,FJ-2was selected as the binder.Experimental results showed that：the bulk density and molding density of the molding powder prepared by used Type 3cubic polyhedron LLM-105 was significantly greater than used type 1and type 2.Fixed the molding density of multi-faceted cube LLM-105 based explosive as 1.763g/cm,detonation velocity was 7743m/s.Compared to S992 and Y971,the detonation velocity improved 12.56% and 13.22%,respectively.
