摘要
为获取变厚度复合材料C梁在受载情况下不同几何特征位置处的应力分布情况,运用Hypermesh对C梁变厚度区域进行局部精细化的网格划分,运用有限元仿真软件ABAQUS对C梁进行数值模拟计算,基于3维Hashin准则判断复合材料的失效行为,并且设计静态拉伸实验对仿真模型进行验证,结果表明本模型可以准确预测变厚度复合材料C梁各区域的应力分布以及承载能力,从而为实际装配生产中装配协调方案的制订提供理论依据,以提高复合材料结构的装配质量。
In this study, in order to obtain the stress distribution at different geometrical features of the C-beam of variable-thickness composite under load, the mesh refinement of the C-beam variable thickness region is performed by Hypermesh, and the finite element simulation software ABAQUS is used. The numerical simulation of the beam is carried out. The failure behavior of the composite is judged based on the three-dimensional Hashin criterion. The static tensile test is designed to verify the simulation model. The results show that the model can accurately predict the stress distribution and bearing capacity of the C-beams with variable thickness composites. Therefore, it provides a theoretical basis for the formulation of the assembly coordination scheme in the actual assembly production to improve the assembly quality of the composite structure.
