Abstract
This paper conducted structural analysis and vibration characteristic analysis to verify the stability of yaw gearboxes for large-capacity wind turbines. For the carriers and housing of the yaw gearbox designed for large-scale wind turbines, structural analysis was performed based on the Load Duration Distribution (LDD) data for extreme load conditions. The results confirmed that all parts met the safety factor of 1.3 or higher, as specified in IEC 61400-1. Additionally, eigenvalue analysis and critical speed analysis were conducted using MASTA11 for the planetary gear train vibration model. The findings demonstrated that within the operating speed range, there was no resonance for mass imbalance or gear mesh frequency.

Keywords
