Abstract

Data of all working conditions can be obtained by uniform design method and regression equations based on the test data of a few working conditions. This method can simplify the wind tunnel test of heliostats and improve the test efficiency. On the same time, the wind load coefficient variation law of heliostat group is obtained. Firstly, 13 different working conditions have been selected according to the uniform design method, and 13 different wind load coefficient values are obtained by the wind tunnel test. The binary nonlinear regression equations have been determined by using the Fall back method and the wind load coefficient variation law. Wind load coefficient regression values are calculated by regression equations. Wind load coefficient variation law under typical working conditions are obtained, and then the overall wind load coefficient variation law of heliostat group under all working conditions are analyzed. Finally it is concluded that the wind load coefficient of isolated heliostat and the wind load coefficient of heliostat group are basically consistent.
