| Abstract: | The compact linear-type towers CSZ1 and CSZ2 for the 500 kV EHV transmission lines are described.According to space beam-rod hybrid structure approach,the finite element model is established by ANSYS.Through by the modal analysis,the natural frequency,vibration modes of the models can be achieved.Based on the above analysis,the first-order approximation formula used in the engineering commonly is revised to estimate the natural frequencies of this type towers. |
