有限元分析在跟踪式光伏支架中的应用进展OA

Against the backdrop of China's goals of emission peak and carbon neutrality and energy transition,PV power generation has experienced rapid development.Tracking PV brackets have been widely used due to their ability to significantly improve the power generation efficiency of PV modules,their structural design directly affects the stability and economic benefits of PV power generation systems.Finite element analysis is a powerful analytical tool that plays a crucial role in the design of tracking PV bracket structures.This paper first introduces the advantages and classification of tracking PV brackets.Then,the establishment of the finite element model for the tracking PV bracket is analyzed from four key elements:unit selection,material properties,displacement boundary conditions,and load application.Finally,the research progress of finite element analysis in tracking PV brackets is summarized from three aspects:stress performance,wind resistance performance,and structural optimization design.The research results show that establishing a refined finite element model for tracking PV bracket connectors,connection nodes,etc.can more accurately reflect the true mechanical properties,failure modes,etc.of tracking PV brackets.The research results can provide a reference for explore safer,more economical,and more efficient forms of tracking PV bracket structures or new forms of PV bracket structures through finite element analysis and optimization design methods.
