摘　　要：采用Maxon Cinema 4D R21建立三维模型,利用3D打印技术打印出桁架球填充交织网管复合结构。对3D打印的不锈钢桁架球、铝合金薄壁管以及桁架球填充交织网管复合结构进行单向轴向压缩试验,得出试验曲线,计算它们的吸能指标,研究桁架球填充交织网管复合结构和其他两者的吸能特性有何不同。结果表明,复合结构可直接影响结构冲击变形程度和吸能能力,三种结构中,复合结构所能承受的载荷最高,桁架球所能承受的载荷最弱。经过试验研究,薄壁管的缓冲吸能特性介于铝合金薄壁管和桁架球之间。Absrtact Maxon Cinema 4 D R21 was used to build 3 D model,and the composite structure of truss ball filled interwoven network tube was made by 3 D printing.The uniaxial compression tests of 3 D printed truss ball,aluminum alloy thin-walled tube and composite structure filled with truss ball and interwoven network tube were carried out,and studied the difference between the composite structure of truss-sphere filled interlaced network tube and the other two structures in the energy absorption characteristics.The results show that the deformation degree and energy absorption capacity of the composite structure are directly affected by the impact.The composite structure can bear the highest load and the ball truss can bear the weakest load.The experimental results show that the energy absorption characteristics of the thin-walled tube are between the aluminum alloy thin-walled tube and the truss ball.
