摘要
本计算方案包括聚能装药药柱及药型罩全部几何参数,以及炸药的密度、爆速、多方指数。计算压垮及射流参数时,采用了不可压缩流体模型。压垮速度按平板抛掷模型进行计算,并以圆筒内聚压垮实验结果作了修正。侵彻按准定常过程进行计算,同时考虑了靶板强度及射流断裂的影响。对各类型装药压垮参数、射流参数及侵彻过程的计算结果表明,计算值与实侧值是相当一致的。使用本计算程序(JPGS),不仅可对现有装药进行各参数计算,而且可用于新装药结构设计的性能预报,并可定量分析各装药参数改变时对穿深的影响规律。
The present calculation method involves all the geometric parameters for the cartridges of shaped charges and their liners as well as the density, detonation velocity and multiple power index of explosives. When collapse and jet parameters are calculated, uncompressible flow models are adopted, collapse velocity is calculated on flat plate projectile model and is modified by the results of cylindrical cohesive collapse tests. Penetration is calculated in accordance with quasi-steady process, and the effects of target strength and break-up of jets are also considered. The calculated results of collapse parameters of various charges, jet parameters and penetration proeess indicate that calculated values are in perfect compliance with real values.Applying this program (JPGS program), we can not only calculate variousparameters for the available charges, predict the performance of newly-designed charges, but also quantitatively analyse the rules of effccts of charge parameters varied on penetration.
