山地大跨度鱼腹式双层索柔性光伏支架受力分析OA

Large span flexible supports are widely used in flat and regularly shaped areas,and the application of large-span flexible supports faces many challenges due to the undulating terrain conditions in mountainous areas.Taking the actual photovoltaic power generation project in a mountainous area of Guizhou as an example,based on the terrain data measured on the site,an accurate mechanical analysis model was established using finite element software to study the effects of different effective cable diameters and cable pre stresses on the overall deflection of a large-span fish belly double-layer cable flexible support system.The results show that increasing the effective diameter of the load-bearing cable to reduce the overall deflection is more effective than increasing the effective diameter of the component cable,and increasing the prestress of the component cable to reduce the overall deflection of the flexible support system is more effective than increasing the prestress of the load-bearing cable.And suggestions were put forward for the selection of cable diameter and the size of prestress application.The analysis results can provide some reference for the rational design,optimization selection,and safety and reliability of similar mountain large-span fish belly double-layer cable flexible support systems in the future.
