Abstract

The invention belongs to the field of wind resistance of engineering structures, and in particular relates to a method for establishing an aeroelastic model of a flexible photovoltaic support structure. The invention provides a method for establishing an aeroelastic model of a flexible photovoltaic structure, which can simultaneously meet the similarity in geometric shape, quality and stiffness between the aeroelastic model of the flexible photovoltaic support structure and the prototype, and realize the horizontal tension of the flexible photovoltaic support structure. Reasonable and accurate application of cable and stay cable pretension. The aeroelastic model established by this method can reasonably simulate the aerodynamic shape and aerodynamic characteristics of the prototype structure, and can provide experimental technical support for the wind resistance design of similar flexible photovoltaic support structure engineering.

Description

technical field [0001] The invention belongs to the field of wind resistant design of engineering structures, in particular to a method for establishing an aeroelastic model of a flexible photovoltaic support structure. Background technology [0002] As a renewable and clean energy with mature technology, photovoltaic power generation is widely favored by the market because of its good environmental protection and economy. With the rapid development of China's photovoltaic industry, high-quality project construction land is rapidly consumed. Therefore, the full development and utilization of non high-quality space resources (such as beaches, abandoned mountains, etc.) will have broad market prospects. In order to meet the needs of market development, a flexible photovoltaic support structure based on prestressed cable system came into being in recent years. The structure is usually composed of columns, beams, horizontal cables and stay cables. By applying prestress to the cables,...
