Abstract:The engineering algorithm and finite element analysis method of critical buckling load of the wind turbine tower under combined loads were introduced. A 5 MW wind turbine tower was taken as the research object, the critical buckling loads obtained by different methods were compared. The calculation results show that the critical buckling load achieved from the linear buckling analysis is larger because of ignoring the influence of nonlinear factors, while the nonlinear buckling analysis is similar to calculation results obtained from engineering algorithm. According to the calculated results, the proposed engineering algorithm according to the relevant standards has certain limitations, and the finite element method is needed to carry out auxiliary analysis in the actual calculation, meanwhile, a nonlinear buckling analysis method considering the initial defects is put forward. © 2017, Editorial Board of Acta Energiae Solaris Sinica.
