[0003] 1. The dynamic characteristics of wind turbine blades in actual use will be affected by various factors such as the working environment, material properties, and wind direction. However, the existing research device has a single experimental environment and cannot truly reflect the performance of wind turbine blades in the actual working environment. Dynamic characteristics

[0004] 2. In order to test the influence of different wind directions on the dynamic performance of wind turbine blades in the existing experimental device, the direction of the wind turbine nacelle will be changed to change the direction of the wind turbine blades. The change of the direction of the wind turbine nacelle depends on the disassembly and fixed connection between the nacelle and the tower , time-consuming and labor-intensive, poor flexibility
