Based on UG and ADAMS software, the virtual prototype of a large wind turbine is established in this paper. Through the dynamic simulation of wind turbine tower, the time domain and frequency domain of vibration acceleration of X and Y direction on tower is obtained and compared to the actual measured data. The analysis results provide a theoretical basis for optimal structure design and further improvement of wind turbine.

Large Wind

In recent years, wind turbine tower buckling and blade broken often happened. Large wind turbine load and insufficient fatigue strength should be the main reasons. To prevent this case, load measurement of the wind turbine is necessary. The wind turbine load measurement is one of the type tests of wind turbine. The load of the wind turbine structure components will strongly affect the safety and life span of the wind turbine. The wind turbine load measurement can help the wind turbine manufacturer and wind farm operator to know the structural response of the wind turbine components with different load cases. According to the IEC 61400-13 standard, a method of the wind turbine load measurement is introduced in this article. Meanwhile, the measurement results are given in this article. The results indicate that the accuracy of this measurement method can fulfill the requirements of the related standards.

The buckling of 2.5MW horizontal axis wind turbine tower tube (5.8m*3.2m*95.2m) is studied by theoretical analysis and numerical simulation. The buckling critical value of tower under axial force is found by theoretical method. The buckling modal of tower under axial force, wind pressure, bending moment and lateral force is simulated by ANSYS software. The buckling of tower with opening and frame at the bottom is also simulated by ANSYS software. The results show that both load and opening have influence on buckling performance, different load and opening have different impact to buckling of tower tube.
