摘　　要：本文基于有限元仿真,分析了车轮移动载荷作用下光伏高速公路组件的力学响应。通过对不同厚度的混凝土基座侧壁进行仿真,考察了厚度变化对透明层应力、变形与结构稳定性的影响。结果表明,随着侧壁厚度的增加,光伏组件的最大应力和变形逐渐减小,但当厚度达到90 mm时,物理量的变化趋于平缓,进一步增厚效果有限。同时,考虑到过厚的基座会减少光伏电池面积,影响发电效率,90 mm的侧壁厚度为最佳选择。本文为光伏高速公路的结构设计和优化提供了理论支持。Based on finite element simulation,this study analyzes the mechanical response of photovoltaic high-way components under moving wheel loads.By simulating different thicknesses of the concrete base sidewalls,the effects of thickness variations on the stress,deformation,and structural stability of the transparent layer were examined.The results indicate that as the sidewall thickness increases,the maximum stress and deforma-tion of the photovoltaic components gradually decrease.However,when the thickness reaches 90 mm,the changes in physical quantities become more gradual,and further thickening yields limited benefits.Addition-ally,considering that an overly thick base reduces the area of photovoltaic cells and impacts power generation efficiency,a sidewall thickness of 90 mm is identified as the optimal choice.This study provides theoretical sup-port for the structural design and optimization of photovoltaic highways.
