地垫拼装板是常用的运动场地面材料，可直接铺装在平整的地面，其结构设计形式多样，具有垂直减震和结构承载等良好的力学性能。目前针对地垫拼装板结构力学性能的研究工作较为罕见，为更好地了解这种结构的承载性能，通过数值方法和试验研究对其承载性能进行分析。选取4种常见的拼装板，建立其单胞模型并进行稳定性分析，同时采用3D打印技术制作单胞模型，并进行压缩承载试验。对比其压溃变形模式、载荷-位移曲线等获得不同拼装板的承载性能，结果表明：单位质量下米字型单胞构型具有较好的承载性能，但该结构承载能力对于初始几何缺陷敏感程度较高。研究成果可为拼装板结构设计提供参考。

Floor mat panels are widely used as sports flooring materials that can be directly laid on flat surfaces. These structures exhibit diverse design configurations and demonstrate excellent mechanical properties including vertical damping and structural load-bearing capacity. Current research on the mechanical properties of such panel structures remains limited. To systematically investigate their load-bearing characteristics, numerical simulations and experimental methods were adopted. Four representative panel configurations were selected for analysis, with corresponding unit cell models established for stability evaluation. 3D printing technology was utilized to fabricate unit cell specimens for compressive loading experiments. By comparing crushing deformation patterns and load-displacement curves, the load-bearing performance of different panel configurations was comprehensively evaluated. The findings reveal that the mi-shaped unit cell configuration demonstrates superior load-bearing efficiency per unit mass, while exhibiting higher sensitivity to initial geometric imperfections. The research results provide valuable insights for optimizing the structural design of floor mat panels.
