풍하중에 의한 경사진 송배전선의 진동 해석

초록

This study focused on the vibrations of inclined transmission line subjected to wind load. The dynamic model of the inclined transmission line was derived using the assumed modes method (AMM). To this end, the kinetic and potential energies, as well as the virtual work by the wind load, were derived. Then, the equations of motion were derived using the Lagrange equation. Theoretical results indicate that wind load causes in-plane vibrations of higher frequency and out-of-plane deflection due to static load.
