Abstract
A hub mating mechanism for single blade installation of offshore wind turbines. The mechanism includes a rigid circular snap ring having circumferential contact with the hub, spring damper, force actuator, buffer plates made from resilient composite material, controller and electric motor. The ring is connected to the buffer plates through the spring damper and the force actuator. The roots of the buffer plates are connected to the outer edge of the hub by hinges. The force actuator is driven by the controller and electric motor placed in the nacelle. Multiple flange holes are formed in the blades and the hub fixed together through bolts after the mating is completed. Assembly and testing of the hub mating mechanism can be performed during component assembly onshore. The hub mating mechanism includes the circular snap ring, buffer plates, force actuator, spring damper, controller and electric motor which are off-the-shelf commercial products.
