Abstract

This paper addresses the issue of buckling in slender tubes under axial compression by introducing the Miura-ori origami configuration to study its impact on the buckling characteristics of slender tubes. First, the unit cell structure of the Miura-ori origami tube and the design of the origami slender tube are described. Then, taking the typical Miura-ori tube as an example, an analysis of its mechanical performance under axial compression is conducted to investigate its improvement in buckling control. To explore optimal mechanical performance, a square tube is used as a comparison to study the effects of different geometric parameters on the mechanical properties of the Miura-ori tube. The results indicate that as the length of the parallelogram increases, the internal angle decreases, the thickness decreases, and the crease weakening coefficient decreases, overall buckling control of the slender tube becomes more effective. Finally, response surface methodology is employed to analyze the combined influence of slenderness ratio, crease weakening coefficient, and internal angle on buckling control performance. The interaction between parameters is visualized, providing insights for parameter optimization.

折纸细长管屈曲控制的数值分析

本文通过引入Miura-ori折纸构型，研究了轴向压缩下细长管的屈曲问题，并对其屈曲特性进行了研究。首先，介绍了三浦ori折纸管的单细胞结构和折纸细长管的设计。然后，以典型的Miura-ori管为例，对其轴向压缩力学性能进行了分析，探讨了其在屈曲控制方面的改进。为了探索最优的力学性能，以方形管为对照，研究了不同几何参数对Miura-ori管力学性能的影响。结果表明：随着平行四边形长度的增大、内角的减小、厚度的减小和折痕弱化系数的减小，细长管的整体屈曲控制更加有效；最后，采用响应面法分析了长细比、折痕弱化系数和内角对屈曲控制性能的综合影响。参数之间的相互作用是可视化的，为参数优化提供了见解。

期刊介绍： The International Journal of Non-Linear Mechanics provides a specific medium for dissemination of high-quality research results in the various areas of theoretical, applied, and experimental mechanics of solids, fluids, structures, and systems where the phenomena are inherently non-linear. The journal brings together original results in non-linear problems in elasticity, plasticity, dynamics, vibrations, wave-propagation, rheology, fluid-structure interaction systems, stability, biomechanics, micro- and nano-structures, materials, metamaterials, and in other diverse areas. Papers may be analytical, computational or experimental in nature. Treatments of non-linear differential equations wherein solutions and properties of solutions are emphasized but physical aspects are not adequately relevant, will not be considered for possible publication. Both deterministic and stochastic approaches are fostered. Contributions pertaining to both established and emerging fields are encouraged.
