[0036] One, at first introduce method step of the present invention, specifically as follows:
[0037] Step 1. For the transmission line to be analyzed, use GoodyGIS software to capture the elevation data of the surrounding terrain where the transmission tower is located or obtain data from relevant geographic websites, and use the Solidworks Scanto3D plug-in to inversely fit the elevation data point cloud to obtain the terrain surface. Use the ICEM software in the ANSYS package to establish the side and top surfaces of the computational domain, and then establish the entire computational domain.
[0038] Step 2: Use the calculation domain model in step 1 to continue grid division in ICEM software, set the boundary layer grid for the calculation domain, and control the size of the grid in the height direction of the bottom surface to 1m-2m to ensure that the calculation results of the wind field are fine The degree can meet the needs of the finite element calculation of the tr...
