单柱固定光伏系统受荷特性及影响机制
Load characterization and influence mechanisms of single-column fixed photovoltaic systems
摘要
Abstract
A 3D numerical model of single-column fixed photovoltaic module-support-foundation integration is constructed to investigate the force and deformation characteristics of the fixed photovoltaic system.under self-weight,wind,snow,and"wind-snow"loads.The influence mechanisms of the elastic modulus of bracket,the concrete strength,the length of purlins,and the depth of pile founda-tion have been revealed to propose the corresponding optimization design suggestions.The results show that under the self-weight and wind load,the deformation of the near-ground end of the component is smaller than that of the far-ground end.Under snow load and"wind-snow"load,the deformation of the near-ground end is larger than that of the far-ground end,and the stress concentration areas are mainly located between different adjacent panels.The maximal stress in the bracket is concentrated in the joints of purlin and diagonal girder,which is larger than the yield strength and affect the system stability.The maximal displacement and stress of the components,braces and pile foundations decrease with the increase of the elastic modulus of braces,the concrete strength and the burial depth of pile foundations,but increase with the increase of the length of purlins.In consideration of the econo-my and safety,the system stability can be improved by the increase in the elastic modulus of braces,the concrete strength and the burial depth of pile foundations,and the decrease in the length of purlins.关键词
