Abstract: A wind field interpolation simulation method based on isogeometric sampling, the main steps of generating a wind speed time series in the present invention are as follows: first, inputting basic parameters of wind field simulation and the number of initial sampling points, and selecting the sampling points by an isogeometric sampling method. Then calculating the maximum relative error of all frequency bands by a relative error defined, and judging a fitting error and an allowable error given. If the fitting error is greater than the allowable error, increasing the number of sampling points and reselecting the sampling points; if the fitting error is less than or equal to the allowable error, finishing point selection, and using an interpolation function to calculate a lower triangular matrix required by the simulation. Thus a fluctuating wind field can be generated by a harmonic superposition method.
