Applicable to wind turbine yaw passive brake friction plates, including technical requirements regarding performance, testing, and inspection. The design of the friction material formula should fully account for the actual operating conditions and demands of wind turbines (such as the uncontrollability and randomness of wind, with instantaneous changes sometimes exceeding 10m/s). The brake operates under unstable load conditions, where the braked part may experience shaking and vibrations due to changes in wind speed. The impact of frequent turbine cut-ins and cut-outs on the friction plates should also be considered.
