Document Type and Number:
WIPO Patent Application WO/2023/236172
Kind Code:
A1
Abstract:
An isogeometric sampling-based wind field interpolation simulation method, relating to the technical field of structural wind engineering. In the present invention, main steps for generating wind velocity time history comprise: firstly, inputting basic parameters of wind field simulation and the number of initial sampling points, and selecting sampling points by using an isogeometric sampling method; calculating a relative error maximum value of all frequency bands by using a defined relative error, and comparing a fit error with a given allowable error; if the fit error is greater than the allowable error, increasing the number of sampling points, and re-selecting sampling points; if the fit error is less than or equal to the allowable error, completing the selection of sampling points, and calculating, by using an interpolation function, a lower triangular matrix required for simulation; then generating a fluctuating wind field by using a harmonic superposition method. According to the present invention, interpolation points selected by isogeometric sampling have good representativeness, the statistical characteristics of the wind velocity time history obtained by combining subsequent interpolation and harmonic superposition are well simulated, and the simulation efficiency is greatly improved; moreover, the method is simple to operate and has a reasonable theoretical background.
