Parametric Analysis of Lattice Sandwich Cylinder Torsional Stability

  • 摘要: 针对扭转载荷作用的四面体点阵夹芯圆筒,以基于等质量圆壳结构的性能增强系数为评价指标,利用有限元数值方法,对点阵杆截面形状、圆筒蒙皮厚度、单胞相对密度、单胞数目及单胞构型对结构扭转稳定性的影响进行了参数化分析。结果表明:结构扭转稳定性能受单胞相对密度和蒙皮厚度变化显著影响,但不同截面形状的等截面积实心杆点阵结构的扭转屈曲性能基本相同,包含更多的点阵单胞有利于增强结构扭转稳定性,而较小相对密度时杆长短的点阵单胞夹芯圆筒扭转性能更具优势。计算结果对点阵夹芯圆筒的设计具有指导意义。
