WIND DYNAMICS TESTING ON DAHAN HELIOSTAT
The aperture area of DAHAN heliostat is 100m2, and the center of drive mechanism is 7m above the ground. The purpose of this study is to provide wind load reference for the structural design of heliostat by means of wind turnnel test. The test mainly consisted of the measurement of time-history wind pressure on heliostat model under various operating conditions of vertical and horizontal wind direction, and the measurement of forces and moments of heliostat with wind tunnel balance. On the basis of data processing and calculation, mean wind pressure coefficient, root-mean-square wind pressure coefficient and the maximum wind pressure of each test point and blockage were obtained in the wind speed of 14m/s, which are used to calculate the possible maximum displacement and strain of the heliostat structure.
