Simulation of Fluctuating Wind Pressure for Heliostat by Autoregressive Model Method

摘要

Through statistical analyzing existed wind tunnel tests' time interval data of fluctuating wind speed by heliostat's entrance and fluctuating wind pressure on its surface, various spatial nodes'fluctuating wind pressure's relevant characteristics are obtained. Basing on wind speed spectrum which alters accordingly with height, random sequence of different nodes' corresponding fluctuating wind pressure time interval is simulated by using AR method. The simulation result tallies well with the tentative data.
