The finite element simulation and tests are employed to study the vibration response characteristics of 1.5 MW wind turbines with elastic supports in the horizontal,vertical,and axial directions under random excitation.A finite element model is established to perform modal analysis and random vibration analysis,by which the natural frequency and response amplitude-frequency characteristics in all three directions are obtained.A three-axis acceleration sensor is installed on the base of the wind turbine to obtain the vibration response data in the three directions,with the error between the simulation calculation results and the experimental data found to be within 3%.The findings demonstrate the effectiveness and reliability of the finite element model in capturing the vibration characteristics of the wind turbine with elastic support,which offers insights for optimizing the design of elastic supports and improving the reliability of wind turbine systems.
