With the gradual scarcity of terrestrial resources, mankind's demand for green energy is becoming increasingly strong. As one of the most promising renewable green energy sources in the world, wind energy has huge reserves and is widely distributed. At present, the most widely used wind energy equipment in the world is the wind turbine generator set (WTGS), which converts wind energy into mechanical energy and then into electrical energy for production and living. The WTGS is a complex mechanical equipment system, and its design, manufacture, operation, and maintenance have an important effect on the utilization rate of wind energy and power generation. With the continuous increase in installed
