Paradigm of Numerical Simulation of Spatial Wind Field for Disaster Prevention of Transmission Tower Lines.

Numerical simulation of the spatial wind field plays a very important role in the study of wind-induced response law of transmission tower structures. A reasonable construction of a numerical simulation method of the wind field is conducive to the study of wind-induced response law under the action of an actual wind field. Currently, many research studies rely on simulating spatial wind fields as Gaussian wind, often overlooking the basic non-Gaussian characteristics. This paper aims to provide a comprehensive overview of the historical development and current state of spatial wind field simulations, along with a detailed introduction to standard simulation methods. Furthermore, it delves into the composition and unique characteristics of spatial winds. The process of fluctuating wind simulation based on the linear filter AR method is improved by introducing spatial correlation and non-Gaussian distribution characteristics. The numerical simulation method of the wind field is verified by taking the actual transmission tower as a calculation case. The results show that the method summarized in this paper has a broader application range and can effectively simulate the actual spatial wind field under various conditions, which provides a valuable data basis for the subsequent research on the wind-induced response of transmission tower lines.
