The research of this paper includes : ? high - speed photography and flash x - ray radiography are both used to capture the process of al shell ' s great deformation under low pressure . front illuminations are used to get the development of the fracture on the al shell . the relative energy release is analyzed from overpressure curves measured with some sensors 本文的研究內(nèi)容主要包括: ?在受試炸藥經(jīng)歷低應(yīng)力大變形過程的susan試驗中,同時采用高速攝影、閃光x射線照相對彈體的撞靶過程進行了拍攝,得到了殼體膨脹變形過程圖像,并使用前照明技術(shù)觀察到了鋁殼表面產(chǎn)生的裂紋及其發(fā)展變化過程;從壓力傳感器測量的空氣沖擊波超壓曲線,獲得反應(yīng)釋放總能。
