Optimizing Design of Axial Prefabricated Fragments
摘要
Abstract
In order to study the influence of shell thickness, detonation velocity, and initiation point position on the average flight angle of axial prefabricated fragments, numerical simulation of the accelerated process of the axial prefabricated fragments was carried out with the Lagrange method using LS-DYNA. Regarding average flight angle of fragments as index , orthogonal optimization method was applied to analyze the primary and secondary relations of the three factors influencing the average flight angle. The result indicates that shell thickness is the dominant factor, explosive detonation velocity comes second, and initiation point distance impact is minimal. An optimum combination of every level of three factors affecting the average flight angle is gained, through which the corresponding fragments average flight angle is 4. 520°.关键词
