| 摘 要： | 进行了超高分子量聚乙烯(UHMWPE)平面层合板、平面夹芯结构以及球面夹芯结构的弹道侵彻实验研究,发现凸球面结构的抗侵彻能力低于平面结构,根据实验现象对球面结构初始曲率的不利影响作了初步分析.应用DYTRAN软件对不同曲率的UHMWPE层合板弹道侵彻进行了数值仿真,分析了层合板曲率对弹道性能的影响规律,认为曲率对层合板变形的限制作用以及由此导致的应力集中是造成抗侵彻能力下降的主要原因.

| Abstract: | Ultra-high molecular weight polyethylene(UHMWPE) laminates,plane sandwich structures and spherical sandwich structures were studied with ballistic penetration tests,and lower anti-penetraion performance of convex spherical structures was found than that of plane structures.Disadvantage of initial curvature of spherical structures was elementarily analyzed based on experimental phenomena.Ballistic penetration of UHMWPE laminates with different curvatures was numerically simulated with DYTRAN FEM software,and... |
