Research on the Control of Fatigue Loading System of Wind Turbine Blade Biaxial Hydraulic Actuator

Aiming at the problems of insufficient excitation force and long test period in the fatigue test experiment of the current wind turbine blades using the uniaxial loading scheme, this article have designed a biaxial fatigue loading device driven by a hydraulic actuator, and established the mathematical model of this system. Due to the problem of unsynchronization of the actuators in the same direct...
