Description

technical field [0001] The invention relates to a method for finite element parameterized modeling and mechanical calculation of a power transmission steel pipe pole. Background technique [0002] The transmission steel pipe pole is a single pole structure, which bears the force of the conductor under various working conditions in the urban power transmission line project. Due to the small design span, the arrangement is relatively dense and the consumption is relatively large. The cost of steel pipe poles is affected by factors such as load size, manufacturing process, construction method, transportation distance, operation and maintenance, etc. The above factors should be considered comprehensively in the design. [0003] Usually, the transmission steel pipe rod is a variable cross-section rod, and the cross-sectional shape is a regular 4, 6, 8, 12, 16 polygon or circle, and the cross-arm structure is a regular 6-gon cone or a 4-gon eccentric cone. The joints, cylinder jo...
