摘要:
为了对复合战斗部预制破片发散角进行有效控制，应用ANSYS/LS-DYNA 3D非线性有限元仿真软件，研究预制破片类型、直径、材料、间距等对复合毁伤元破片场的影响，并对确定的结构进行试验验证。结果表明，采用球形破片能够得到内、外分布均匀的破片场。研究破片材料、直径、间距对复合战斗部预制破片发散角的影响，得到了复合战斗部基本结构：球形破片材料选择钨合金，破片直径为10 mm，内、外圈破片间距为1 mm。对设计的复合战斗部进行静爆试验，试验结果与仿真结果基本一致。
Abstract:
In order to effectively control the divergence angle created by the prefabricated fragments of a warhead composite, ANSYS/LS-DYNA 3D nonlinear finite simulation was used to study the broken fragment field of the combined damage elements in view of the type, diameter, material and spacing of the pre-fragments. The determined structure was tested and verified. The results show that spherical fragments can be used to obtain uniform distribution of fragments inside and outside. The influence of fragment material, diameter and spacing on the divergence angle of combined warhead pre-fragment was also studied, and the basic structure of combined warhead was obtained. Tungsten alloy was selected as the spherical fragment with a diameter of 10 mm and a spacing of 1 mm between its inner and outer ring. The static detonation test was carried out for the designed combined warhead, and the test results were basically consistent with the simulations.
