光伏跟踪支架梁结构轻量化设计及风致疲劳分析
Lightweight Design of Photovoltaic Tracking Bracket Beam Structure and Wind-Induced Fatigue Analysis
摘要
Abstract
The lightweight design of photovoltaic tracking brackets is explored in this paper.A finite element model of the photovoltaic bracket is established using Abaqus software and wind-induced fatigue analysis is conducted.Based on the stress situation of each supporting component,the variable density method is used to optimize the to-pology of the purlin with the maximum stress in order to achieve the engineering design of the purlin.Based on the interaction between the Isight platform and Abaqus backend code,a multi island genetic algorithm is integrated to optimize the parameters of the cross-section of the main beam and purlin,reducing the weight of the main beam and purlin while ensuring their maximum stress and their displacements do not increase.The harmonic superposi-tion method is used to generate the time curve of pulsating wind load,and the damage accumulation theory and rainflow counting method are used to calculate the service life of the beam structure,thereby improving the overall service life of the optimized beam structure.关键词
