力学折纸超材料以折纸思想为基础，通过设计巧妙的特征结构来实现表观材料的特殊力学行为。为进一步融合折纸超材料和拉胀超材料的性能优势，受折纸范式启发设计一种多向的拉胀折纸超材料（AOMM）。基于静定结构承载变形机制，分析多向AOMM的负泊松比效应，建立相对密度、折叠效率、弹性等效本构以及载荷平台的理论模型，通过曲面响应揭示几何参数对多向AOMM折叠载荷的影响规律。采用热塑性聚氨酯（TPU）基材3D打印多向AOMM试件，通过准静态压缩实验进行变形、承载和吸能特性的分析。结果表明：TPU AOMM具有一定的形状恢复能力、负泊松比效应和稳定的吸能平台，平台门槛应变和相对密度的理论值与实验结果吻合较好。研究结果可为拉胀折纸超材料的设计和应用提供参考。

Based on the idea of origami, mechanical origami meta-materials can realize the special mechanical behaviour at the apparent material level by designing ingenious characteristic structures. To further integrate the performance advantages of origami and auxetic meta-materials, a novel multi-directional auxetic origami meta-material (AOMM) inspired by the origami paradigm was designed. Based on the load-bearing deformation mechanism of the stationary structure, the negative Poisson's ratio effect of the multi-directional AOMM was analyzed, the theoretical models of relative density, folding efficiency, equivalent elastic constitutivity and load plateau were established, and the influence law of geometric parameters on the folding load was revealed by the surface response. The multi-directional AOMM specimen was 3D printed using thermoplastic polyurethane (TPU) as the base material, and the deformation, load bearing and energy absorption characteristics were analyzed by quasi-static compression experiment. The results show that TPU AOMM has a certain shape recovery ability, a negative Poisson's ratio effect and a stable energy absorption plateau, and the theoretical values of the threshold strain entering load plateau and the relative density are in good agreement with the experimental results. The present research results can provide a reference for the design and application of auxetic origami meta-materials.
