摘要/Abstract

摘要： 制备一种玄武岩纤维/铝合金层合板复合结构,通过试验和仿真,探讨该复合结构的拉伸、压缩、剪切、弯曲和抗冲击特性。采用连续壳单元模拟纤维层,建立低速冲击仿真模型,从能量吸收、接触力和层合板损伤程度3个方面,研究铺层结构和冲击载荷角度对纤维金属层合板抗冲击性能的影响。最后,将纤维金属层合板应用于发动机罩外板,进行发动机罩静态刚度和行人头部碰撞仿真分析。结果表明,与原发动机罩相比,纤维金属层合板发动机罩的弯曲刚度和扭转刚度均有不同程度提高,行人头部保护性能得到改善。

Abstract: A composite structure composed of basalt fiber and aluminum alloy laminates are manufactured and its tensile, compression, shear, bending and anti-impact characteristics are explored by test and simulation. Then, a low-speed impact simulation model is set up with fiber layer simulated by continuous shell element, and the effects of ply laying structure and the angle of impact load on the anti-impact performance of fiber-metal laminates are studied in terms of energy absorption, contact force and laminate damage degree. Finally, fiber-metal laminates are applied to the external panel of engine hood and a simulation on the static stiffness and pedestrian head collision is also performed. The results show that compared with original engine hood, the bending and torsional stiffness of engine hood using fiber-metal laminates are enhanced to different degrees with pedestrian head protection performance improved

Key words: basalt fiber, fiber-metal laminate, low-speed impact performance, engine hood, pedestrian head collision simulation
