摘　　要：通过声共振混合试验样机对固体质量分数为86%的PBX炸药(高聚物黏结炸药)进行声共振混合的均匀性及工艺安全性试验研究,试验量级为150 g。试验结果表明,PBX炸药在声共振混合作用下进行内部的撕裂缠结,依次形成球状混合块和整场沸腾状混合浆,整个混合时间约为1 000 s。成分分析表明,声共振能实现固体质量分数为86%的PBX炸药均匀混合;静电和温度测量表明,整个混合过程中,静电电压几乎维持在0 k V左右,物料内部摩擦生热速度远远低于物料对外的热散失速度,混合过程中静电安全和热安全在可控范围内。An experimental study on the mixing uniformity and process safety of resonance acoustic mixing （RAM） of PBX explosive with 86% solid mass fraction was carried out by RAM experimental prototype, and the sample scale was 150 g. Experimental results show that the PBX explosive is involved in tanglement and tear in the mixture, followed by the for- mation of a spherical mixed block and blended pastes in turn, and the total mixing time is about 1 000 s. Component analy- sis of mixture shows that the RAM could realize uniformly mixing of PBX explosive. Electrostatic and temperature measure- ments show that the electrostatic voltage is almost 0 through the mixing process, and friction heating rate is slower than heat dissipation rate. Electrostatic and thermal risk is within a controllable range.
