- HFFB Test and Wind-Induced Vibration Analysis on 1 000 kV Transformer Frame Wennian Shang Jun Gong Xudong Zhi Haoyang Wang Ingeniería High wind shape factor finite element analysis 1000 kV transformer frame In order to propose a complete, wind-resistant design method for ultra-high voltage (UHV) transformer frames, the wind-induced vibration characteristics of a 1 000 kV transformer frame (TF1000) were studied using a high-frequency force balance (HFFB) test. Five section models and one whole model of the TF1000 were designed and constructed using 3D printing, and these were evaluated in a wind tunnel by means of HFFB tests for multiple loading scenarios. The finite element method (FEM) was used on the test data to analyze the wind-induced vibration on the TF1000. The results demonstrate that the shape factor of the TF1000 is significantly affected by the flow field type and solidity ratio; the minimum value occurs when the wind direction is between 30 and 45°. Moreover, all the shape factor values obtained by the test are larger than those established by the Chinese code. The wind-induced vibration analysis indicates that the most unfavorable wind direction for the TF1000 is approximately 60°, with a wind-induced vibration coefficient between 1,7 and 3,9. 2023 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64379907005 https://www.redalyc.org/journal/643/64379907005/ https://www.redalyc.org/journal/643/64379907005/html/ https://www.redalyc.org/journal/643/64379907005/64379907005.epub https://www.redalyc.org/journal/643/64379907005/movil 10.15446/ing.investig.88403 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.1 Vol.43
