摘　　要：笔者聚焦于光伏支架系统中的连续檩条,运用数值模拟Midas软件深入分析其在不同柱距布置条件下的力学性能,旨在优化柱距方案以提升结构经济性与安全性。以广西某农光互补项目为背景,选取2×14阵列的固定支架,通过改变柱距布置,分析檩条在风压组合与风吸组合下的内力分布。研究表明:在风压组合控制下,大边跨方案为最优方案,而在风吸组合控制下,小边跨方案更优;设置拉条系统时,大边跨方案为最优方案,而不设置拉条系统时,小边跨方案更佳。该研究成果对光伏支架结构设计具有重要指导意义,可为相关工程实践提供参考。This study focuses on the continuous purlins in photovoltaic(PV)support systems,employing numerical simulation Midas software to deeply analyze their mechanical performance under different column spacing arrangements.The aim is to optimize column spacing schemes to enhance structural economy and safety.Taking an agricultural-photovoltaic complementary project in Guangxi as a case study,a 2×14 array fixed support structure is selected.By varying column spacing arrangements,the internal force distribution of purlins under wind pressure combinations and wind suction combinations is analyzed.The results indicate that under wind pressure combination control,the large side-span scheme is optimal,whereas under wind suction combination control,the small side-span scheme performs better;When a bracing system is implemented,the large side-span scheme is optimal,while the small side-span scheme is preferable without a bracing system.These findings provide significant guidance for the structural design of PV support systems and serve as a reference for related engineering practices.
