為得到聚能射流引爆屏蔽PBX和B炸藥的臨界條件,采用某制式聚能裝藥對(duì)不同厚度屏蔽板屏蔽的PBX和B炸藥進(jìn)行了侵徹引爆實(shí)驗(yàn),得到屏蔽炸藥臨界引爆的屏蔽板厚度;通過(guò)閃光X射線照相實(shí)驗(yàn)測(cè)定了與臨界屏蔽板厚度相對(duì)應(yīng)的射流穿靶后的剩余射流頭部速度和直徑,得出引爆屏蔽PBX和B炸藥的射流引爆判據(jù)u2d分別為38。
Compressive behaviors of a polymer bonded explosive (PBX) and pressed Comp.
利用萬(wàn)能材料試驗(yàn)機(jī)對(duì)一種高聚物粘結(jié)炸藥(簡(jiǎn)稱PBX炸藥)和壓裝B炸藥進(jìn)行了準(zhǔn)靜態(tài)壓縮實(shí)驗(yàn),得到了兩種炸藥在不同應(yīng)變率下的應(yīng)力應(yīng)變曲線。
