%X 负泊松比结构具有特殊规变形行为和吸能特性，是一种具有广阔应用前景的新型结构。然而目前的研究大多仍停留在微观理论层面，对宏观力学性能的研究较少，因此本文提出了一种聚氨酯椭圆负泊松比结构(PES)，采用实验模拟与数值模拟的方法，与内凹负泊松比结构(PCS)进行力学对比以及分析长宽比对结构的影响，突出PES在承载吸能方面的优势，同时采用参数分析研究结构形式和材料属性对PES泊松比及弹性模量的影响，结构在高端装备制造、抗震隔振等领域的应用提供科学依据和技术支撑。
Negative Poisson’s ratio structure has special deformation behavior and energy absorption characteristics, which is a new structure with broad application prospects. However, most of the current research is still at the micro theoretical level, and there is less research on the macro mechanical properties. Therefore, this paper proposes a polyurethane elliptical negative Poisson’s ratio structure (PES), which uses the methods of experimental simulation and numerical simulation to carry out mechanical comparison with the concave negative Poisson’s ratio structure (PCS) and analyze the influence of length width ratio on the structure, highlighting the advantages of PEs in energy absorption, and using parameter analysis to study the influence of structural form and material properties on the Poisson’s ratio and elastic modulus of PES, so as to provide scientific basis and technical support for the application of the structure in high-end equipment manufacturing, seismic isolation and other fields.
