摘　　要：针对逻辑网络起爆器直径小、长径比大、多拐角结构特点和太安(PETN)基腻子炸药粘度大的性能特征,研究了多流道等比压装药技术,确定了较佳的装药工艺条件为比压80 MPa,保压时间30 min。对等比压装药(0.3 mm×0.3 mm～2.0 mm×2.0 mm)不同沟槽截面尺寸和不同装药拐角(108°～160°)对爆速的影响规律,以及装药最小传爆沟槽尺寸和最大传爆拐角进行了考察,并对等比压装药的理化均匀性、波形同步性进行了试验研究。结果表明,逻辑网络起爆器的最小沟槽传爆尺寸为0.3 mm×0.3 mm,最大传爆拐角为150°,其装药密度范围为1.504～1.507 g.cm-3,装药成分差为0.34%～0.56%,波形同步分散性在0.03～0.05μs之间。The isopressing charging technology with multi-runner device of logical network initiator was studied according to the structural features of small diameter,large aspect ratio,multi-corners of the high viscousity of PETN based putty explosives.The charging process conditions were determined accordingly i.e,pressure is 80 MPa and dwell time is 30 min.The influences of different groove dimensions（0.3 mm×0.3 mm～2.0 mm×2.0 mm） and different corner turning（108°～160°） on detonation velocity were investigated.The minimum groove size and the maximum cokner for propagation of explosion were investigated.The physical and chemical uniformity and wave synchronization for isopressing charging were also studied by experiments.The results show that the least groove dimension is 0.3 mm×0.3 mm,and the biggest degree of corner turning is 150°.The range of charge density is 1.504～1.507 g·cm-3,and the charge composition deviation is 0.34%～0.56%,and the dispersion of the wave synchronization is between the 0.03～0.05 μs.
