    Numerical Simulation of Quasi-static Axial Compression of Carbon Fiber Composite Winding Aluminum Alloy Tube

    • 摘要: 以多层(10层)和少层(3层)碳纤维复合材料缠绕铝合金管(Al-CFRP混合管)为研究对象,采用ABAQUS/Explicit有限元软件建立单层壳模型、多层常规壳模型和多层连续壳模型3种模型,基于Hashin失效准则对混合管轴向压缩变形过程进行仿真,对比了各模型的仿真准确性;将初始峰值载荷、比吸能、平均压缩载荷仿真相对误差和仿真时间进行无量纲化和权重处理,对各模型进行综合评价。结果表明:多层壳模型可以更好地预测混合管在轴向压缩下的损伤变形和吸能特性;对于多层缠绕混合管,最佳模型为多层连续壳模型,对于少层缠绕混合管,多层常规壳模型具有最小的误差。

       

      Abstract: With multilayer (10-layer) and few-layer (3-layer) carbon fiber composite winding aluminum alloy tube (Al-CFRP mixed tube) as the research object, the single-layer shell model, multi-layer conventional shell model and multi-layer continuous shell model were established with ABAQUS/Explicit finite element software. The axial compression deformation process of the hybrid tube was simulated with Hashin failure criterion. The simulation accuracy of each model was compared. The simulation relative errors of the initial peak load, specific energy absorption and average compression load and the simulation time were made dimensionless and weighted to evaluate each model comprehensively. The results show that the multi-layer shell model could better predict the damage deformation and energy absorption characteristics of the hybrid tubes under axial compression. For the multilayer winding hybrid tube, the best model was the multi-layer continuous shell model, while for the few-layer winding hybrid tube, the multilayer conventional shell model had the smallest error.
