Analysis of Compressive Stiffness Characteristics of Tubular Support Structures with Negative Poisson's Ratio
摘要
Abstract
Negative Poisson ratio structures were widely used in engineering because of their unique structural properties,high energy absorption and good deformation adaptability.The performance optimiza-tion of tubular supports was studied with negative Poisson ratio structure in engineering applications.Com-bining structural design and mechanics analyses,the compressive performance of tubular supports was sys-tematically investigated.Based on the unique inward shrinkage deformation characteristics of negative Pois-son's ratio structures,four new tubular stent structures were designed and prepared.By analyzing the stress distribution and load displacement curve through physical compression test and numerical simulation,a multi-dimensional evaluation system was constructed including peak load,energy absorption and compres-sion stiffness.The results show that the stabilitys of FB-H structure is the best under continuous radial pressure,and the compressive strength of FB-X structure and FB-S structure are increased by 42%and 123%,respectively.Different structures show differences under axial loads.The FB-X and FB-S brackets have high rigidity and are suitable for scenarios requiring support stability.The FB-N and FB-H brackets are flexible and suitable for large deformation scenes.关键词
