开阔水域光伏发电结构强度及疲劳分析OA

This paper focuses on the multi-block photovoltaic power generation structure in non-marine open waters,and studies the modeling method for calculating the structural strength and conducting strength analysis.The floating photovoltaic structure on water bears wind,waves and current loads,and the structural strength is a key issue in the design of such structures.The photovoltaic structure developed in this paper is composed of floating cylinders and structural supports in blocks,and multiple blocks are assembled into a whole.Based on the developed structure,a model is established using the finite element method,considering wind,waves and current loads,mooring line influence and eliminating rigid body displacement to establish boundary conditions.Based on the inertial release method,the influence of rigid supports is excluded,and the structural strength in 0° and 90° wave directions is calculated.The stress distribution diagram and deformation diagram of the photovoltaic structure are obtained.The results show that the finite element photovoltaic structure model established in this paper is feasible,the boundary condition processing is reasonable,the results are reliable,and the floating cylinder and support structure meet the strength requirements of the survival conditions.
