Modeling and Modal Analysis of Sliding Yaw Bearing in the Wind Turbine
Sliding yaw bearing works in the complex environment with large load range,so its dynamic analysis is very important.The modal analysis of sliding yaw bearing is not only an effective method for analyzing sliding yaw beatings dynamic characteristics,but also the basis of the dynamic respond analysis.This paper used the parameter design function of UG code to build the 3-D model of sliding yaw bearing and imported the model to ANSYS code to build finite element model.Then the finite element modal analysis was applied after meshing the model.Finally,the Iow-order natural frequency and the vibration mode were obtained.Therefore,the modal analysis of sliding yaw bearing can provide the basis of the dynamic characteristics analysis and optimization design of sliding yaw bearing.Meanwhile,the modal analysis can be considered as the reference to avoid yaw bearing resonance during wind turbine working.
