基于仿真与实验的蛛网结构力学特性分析OA

Finite element simulations were conducted to analyze the influence of radial and circumferential thread numbers on the load-bearing capacity of spiderweb structures,and PMMA was selected to fabricate physical models for experimental validation of the simulation results.The findings show that increasing the number of radial threads significantly enhances the central load capacity,for each additional radial thread,the simulated load increased by approximately 0.66 N,while the experimental load increased by about 0.26 N.The effect of increasing the number of circumferential threads was comparatively smaller but still exhibited a reinforcing tendency,with each additional layer increasing the load by approximately 0.50 N in simulations and 0.18 N in experiments.Overall,radial threads are the dominant factor determining the structural strength,whereas circumferential threads contribute to optimizing stress distribution to some extent.
