Model And Seismic Analysis Of Large-scale Wind Turbine Tower Structure

摘要

The working condition of wind turbine tower structure with a massive engine room and revolving wind wheels is very complex. Tbe paper simplify the wind turbine tower model with finite element analysis software—ANSYS, completed modal analysis firstly, tbe calculations showed that a long time resonance will not happen. Then completed the time-history analysis of tbe structure under vertical and horizontal seismic force, the results showed the top displacement of the tower is 0.32m, meet the control value of deflection. The maximum stress appears nearby the door opening, tbe value is 98.5Mpa, meet the control value of stress.
