摘要

在汽车碰撞产生的弯曲载荷下，复合材料安全构件应具有抵抗变形和耗散碰撞能量的能力。为确定三点弯曲工况中编织碳纤维复合材料薄壁梁的渐进损伤材料模型力学参数，开展了编织碳纤维复合材料力学特性试验和编织碳纤维复合材料方管三点弯曲试验，获得了该材料的基本力学参数、弯曲失效历程及力-变形特性。进而分析了渐进损伤材料模型中各非试验参数对仿真结果的影响，讨论了多层壳建模方法的有效性。通过与试验结果的对比，获得了复合材料渐进损伤模型的非试验参数和有效的仿真建模方法。获得的材料特性可用于该材料结构在相似工况中的碰撞仿真分析。

Abstract

Under the bending load generated by automobile collision, the composite safety components should have the ability to resist deformation and dissipate crashworthiness energy. In order to determine the mechanical parameters of the progressive damage material model of a woven carbon fiber composite thin-walled beam in the three-point bending condition, the mechanical properties test of the woven carbon fiber composite material and the three-point bending experiment of square tubes made by this material were carried out, thus got the basic mechanical parameters, bending failure history and force-deformation characteristics. Then the effects of the non-test parameter in the progressive damage material model on the simulation results were analyzed and the effectiveness of the multilayer shell modeling method were discussed. By comparing with the experimental results, the non-experimental parameters and effective simulation modeling methods for the progressive damage model of composite materials were gotten. The obtained material properties can be used for the crashworthiness simulation analysis of this material structure in similar working conditions.
