Optimization Design of Photovoltaic Bracket Structure Dimensions Using Global Response Surface Methodology

Taking the photovoltaic bracket structure as the research object, this study explores the optimal solutions of various variables in the lightweight design of photovoltaic bracket structures. Based on the finite element analysis results of the structural model under static load conditions, the global response surface optimization algorithm is used to search for the global optimization of the photovoltaic bracket finite element model. The analysis results show that the thickness variable of the purlins is a key design factor for the photovoltaic support structure model. The optimized structure model using the global response surface optimization algorithm reduces weight by 30.79% compared to the original structure as a whole, and the optimized structure model meets the design constraints.
