Abstract: Heliostat is an important component in solar tower power station. A certain type of heliostat was chosen as the research object. Employing the scale model of the heliostat multi-channel synchronous pressure measurement wind tunnel experiments,the wind pressure distriloution test results were obtained under various working conditions. Based on the analysis results,the variation law of structural wind resistance design parameters of this type of heliostats is obtained,and the recommended values of the design parameters of wind resistance suitable for China’s specification are given,the values of wind resistance design parameters also provide a reference for tower solar thermal power station design specifications.
